We Don’t Like

This one is one of the most compact, portable car battery charger that you will ever see. You can easily carry it in your pocket, glove box, backpack or just as you feel convenient about it. But, that doesn’t take anything away from this device as it is powerful enough like any other quality charger that you will ever see in the market. You will get it with the charging adapters for all the main types of electronic devices. The jump starter is capable of starting your vehicle 20 times while given a full charge.

There are ultra-bright on-board LED lights, SOS signal light and the strobe light which lasts for more than 120 hours. The manufacturer has introduced the equipment with excellent safety features such as the over current protection, overload protection, overcharge protection, short circuit safety, and overvoltage safety as well.

Jump-N-Carry JNCAIR

The Jump-N-Carry JNCAIR is a very popular product among all the products due to its capacity and excellent high end features. This is the product which will offer you with 1700 peak amps which is excellent for all the different range of batteries that you are looking to charge. Apart from this, the cold cranking amps are also very important factor to consider and for this charger type, you will have the capacity of 42cold cranking amps.

Then, if you look at the convenience side of this battery charger then the 6inch long cables makes all charging jobs quite easy to handle. You do not need to bring a thing closer to the battery which could be a dangerous thing in case of a possible electric spark. The equipment has a very useful integrated air compressor as well, which comes with an extra-long 1foot coiled hose along with a screw-on chuck.

Plug In Battery Chargers

The plug in car battery chargers might not be that convenient in their usage, but they are good for their versatility.

In the similar manner, they are also good for giving multiple amperage modes such as 10Amp or 7Amp, etc.

Weego claims that the Jump Starter 22s can start up to a 5-liter gas engine or a 2.5-liter diesel; we had no trouble starting the 3.6-liter six-cylinder engine in our test truck. Weego’s scissor-style Smarty Clamps require less effort to open, expand wider, and clamp more securely to battery posts than the clamps on other models, and Weego’s cables are longer and less prone to twisting, making this model easy to use in any engine compartment. And if you hook it up wrong by connecting the clamps to the wrong battery terminals (as we purposely did in our tests), a loud alarm and flashing lights inform you of your mistake so you can reposition the pieces and try again without hurting yourself or your car.

Who this is for

Anyone with a car can benefit from a portable jump starter, because, well, stuff happens. An interior light left on all night, a radio running when you sneak out to your car for a lunch-break nap, or freezing temperatures in the middle of winter can all drain a battery’s charge in many vehicles. You can run down even newer batteries and newer cars. And because the ignition systems in today’s cars are so efficient, you won’t necessarily get a warning—such as the engine cranking more slowly—before it happens. At best, a drained battery is an inconvenience; in the wrong place or at the wrong time, it can be also a safety concern.

Pull Quote

Because the ignition systems in today’s cars are so efficient, you may not get a warning before finding out your car’s battery is run down.

Because a jump starter has its own battery, you simply connect the jump starter’s two cable clamps to the appropriate battery terminals on your car, flip a switch, and crank the engine. You can be on your way again in minutes. Many models have enough power to let you do this several times before you need to recharge the jump starter itself. And the better ones instantly sense if you’ve hooked up the cables wrong, and give you a clear warning.

Although jump starters have long been large and heavy, containing their own lead-acid battery, in the past few years a new wave of small, lightweight, lithium-ion jump packs have appeared that easily fit in a car’s glove box, making them much easier to keep with you for an emergency. Those are the models we researched and tested for this guide.

What makes a good jump starter

When you’re shopping for a portable jump starter, you’ll encounter lots of specs and features. Here are the things that are most important, as well as a couple of features that we don’t consider critical.

Starting power: The power that a portable jump starter can deliver to your engine is the most important factor. And like a car battery, a jump starter is generally rated by cold cranking amps (CCA) or sometimes peak amps (PA). But that doesn’t mean you can easily figure out what types of vehicles a given model is actually capable of starting. Some manufacturers make only a general claim about what engine size their model can start, such as a Vor a 4.0 L. Generally, the bigger the engine, the more battery power it needs to start, and you’ll find a huge range of power outputs for car batteries and jump starters alike.

Flaws but not dealbreakers

We like that the Jump Starter 22s charges via Micro-USB, instead of a proprietary DC jack. This means that you can recharge it from any USB charger you use for your phone or tablet, instead of having to keep track of a special wall or car charger. But Micro-USB ports can take less power than most DC jacks, so the battery inside can’t recharge as fast. In the big scheme of things, this is a minor flaw, especially because the 22s has a relatively small capacity that doesn’t take long to fill anyway. Still, we hope that future versions of the 22s switch to a USB-C port so that we can continue to benefit from the convenience of universal charging and enjoy the faster charging speeds that USB-C offers.

In our first round of testing, the PowerAll Deluxe started our dead 10-year-old Jeep Wrangler with a 4.0 L six-cylinder engine without a problem. It provided 200 amps to boost our battery, in line with the best of the jump starters we tested.

The PowerAll Deluxe also performed well in our early-201tests with the larger 5.7 L Vengine in one of our Ram 1500 pickups. When we connected the PowerAll Deluxe and hit the ignition, it delivered a little over 200 amps, and the truck growled to life. Of the five jump starters we tested on that truck, only three managed to revive it. (We weren’t able to test the Weego 22s on that vehicle.) Even though the other two successful models provided about percent more power than the PowerAll Deluxe in our tests, they both cost twice as much.

Charging AGM Deep Cycle Batteries

One of the leading advantages of AGM deep cycle batteries is these batteries can be charged times faster than flooded deep cycle batteries of the same amp-hour rating. AGM batteries are the most common battery type used in marine applications.

However, unlike flooded batteries, AGM batteries are sensitive to overcharging and they also do not like heat. Therefore, if your deep cycle battery is AGM, choosing the best charger would be a bit more complicated.

A charge to 2.40V/cell (and higher) is fine. However, the float charge should be reduced to between 2.2and 2.30V/cell (summer temperatures may require lower voltages). A battery charger that is dedicated to charging 12V flooded lead acid often have a fixed float voltage setting of 14.40V (2.40V/cell), using it could overcharge the AGM battery.

To protect and maximize the life of your AGM battery, you should select a multi-stage charger that has a setting for AGM. And because AGM batteries can be fully charged very quickly, we would highly recommend that you buy a charger that has max charge current less than 25Ah.

This Optima’s battery charger features many built-in technologies and microprocessors which enhance the performance of 12V AGM batteries, recovers deeply discharged batteries and helps extend battery life. And if you already have an Optima’s marine battery, this charger is probably the best choice.

Charging Gel Deep Cycle Batteries

Gel batteries actually predated the AGM type but are losing market share to the AGM’s. But Gel batteries are still quite common in solar storage systems.

Gel batteries tend to have VERY NARROW charging profiles and can be damaged easily by charging them inappropriately. If you have a Gel battery, do not charge it with a conventional car battery charger. There are several methods for charging gel batteries, however, constant voltage charging is the best way. For this type of charging, a fixed, regulated voltage source is used to charge the battery.

BatteryMINDer 12V 2/4/Amp Wet/Gel/AGM Battery Charger will satisfy you.

This charger is regulated and will not overcharge, no matter what amp selection you make. It is just a matter of how fast you need to charge the battery. Plus, when used as a maintainer, it is guaranteed to maximize the battery life and improve storage capacity. The temperature compensated long-term maintenance stage will add years of service.

Charging Lithium-ion Deep Cycle Batteries

Lithium-ion batteries cannot absorb overcharge. When fully charged, the charge current must be cut off. A continuous trickle charge would cause plating of metallic lithium and compromise safety. They should also operate safely within the designated operating voltages as the battery becomes unstable if inadvertently charged to a higher than specified voltage.

For better battery life and performance, choose a charger that has a setting for lithium. And because all lithium-based batteries are safer at a lower charge, you should consider a model that has a low amp-hour rating (20Ah or less). This is a very good choice.

Charging Your Deep Cycle Battery with a Generator

Using a generator is the fastest way to charge your deep cycle battery during the power outage or when you need to charge deep cycle batteries in your RV as fast as possible. Most inverter generators have a 12V DC output built into them, however, trying to charge a battery using this is almost a waste of time. The 12V DC output is usually limited to around amps, the voltage can fluctuate and is not suited to effectively charge your deep cycle battery.

The best way to charge your deep cycle battery with a generator is to connect a Smart Charger to the 120V AC outlet of the generator. A smart charger uses or more stages to charge the battery bank exactly the way it wants to be charged depending on its state.

Xantrex TRUECharge12V (20A, 40A, 60A) Battery Chargers. These are some of the best deep cycle battery chargers on the market. They are best suited for charging with a generator as they feature low electrical interference and can protect your deep cycle battery against voltage fluctuations and unexpected shutdown.

Charging Your Deep Cycle Battery with Solar Panels

We have discussed the best chargers for solar batteries in our previous guide to choosing the best deep cycle battery for solar power systems. But here are some basic terms that you should know about charging your deep cycle battery with solar panels.

In solar power systems, the batteries cannot be charged without a Solar Charge Controller. A solar charge controller manages the power going into the battery bank from solar panels. It ensures that the deep cycle batteries are not overcharged during the day, and that the power doesn’t run backwards to the solar panels overnight and drain the batteries.

CTEK D250S Dual is a 5-step charger. This is a smart deep cycle battery charger which is designed to obtain energy from DC sources such as alternators, solar panels or wind power and optimises this power to meet the charging requirements of different battery banks.

Maximum Power Point Tracker ) that helps the solar cells produce power as efficiently as possible by taking the most efficient source of energy from the solar panels automatically, and then using the power to charge the battery.

Charging Deep Cycle Battery While On the Water

You’ve been looking around for a way to help pump some juice from the outboard alternator and deliver it to your trolling batteries to extend run times, decrease on-shore charge times and increase battery life. If so these are things you should know.

MinnKota MK-2-DC Dual Bank DC Alternator Charger

Most deep cycle battery systems that we have is 12V. 1volts is simplest and most standard, used in cars, RVs, trolling motors and boats. If you want a small simple power system, 1volts will probably be easiest. But in some applications such as marine or home solar energy systems, where we often build large battery banks that store hundreds or even thousands amp-hours, the 24V or 36V or 48V system has some technical advantages over the 12V system.

You can use a 12V battery charger to charge one 12V battery at a time, but charging your batteries in such way is almost a waste of time. The best way to charge deep cycle batteries in the 24V/36V/48V systems is using a smart charger that provides an adequate output voltage.

Choosing the right battery for your car

First off, you need to find the right battery for your car; a quick look at the owner’s manual will help here, while the internet is a valuable resource. Many suppliers’ websites will allow you to enter your registration number and then tell you which battery is correct. Plus, if you shop around online, you’ll have a good chance of finding a great deal and you won’t need to lug a heavy battery home from the accessory shop or garage.

Before you disconnect your failing old battery, remember that it powers various features in the car, which are likely to be reset. Do you have a code for the stereo, for example? You may need this to use it again when you connect the new battery.

Disconnecting your old battery

Slide the new battery into the cage and reverse the process, connecting the positive terminal first, then the negative. You’ll now need to reset any electricals inside the car – from clocks to stereo to sat-nav. If your car has stop/start, the battery will need to be tuned with the on-board computer, which is why fitting an ECM or AGM battery is probably a job for a professional.

Care for your car battery

Now that you’ve splashed out on a new battery, you want to protect your investment, and the latest chargers have sophisticated programmes to maintain the level of charge. They’re especially useful if you only use your car sparingly – classic car owners swear by these products.

These smart chargers vary the current they pump into the battery to prolong its life. They can even be left attached to a car for long periods of time, and just top the battery up gently. Plus, if your battery is showing signs of being on its last legs, one of these products might be worth a try first; a smart charger can bring a dying battery back to life.

Emergency jump starting

The reason that those old-style chargers boil the electrolytes in a typical flooded battery is because they don’t shut off when the battery has reached capacity. This can be controlled through several methods. Solid state controls use resistors and capacitors to measure the voltage on the battery. These work, but they can fail, leaving your battery melted inside your car.

A microprocessor is essentially a computer for you battery charger. Where a solid-state charger puts amperage to the battery until it shuts off, the smart charger operates in a much different manner. Rather than simply blasting the voltage charge to the battery, the smart charger utilizes a multi-phase charging cycle similar to what the alternator does in the car. Pro-Logix smart chargers from SOLAR use a 7-phase cycle to achieve maximum charging efficiency.

Battery Testing

The last thing you want to do is waste time charging a battery with a bad cell inside. The Pro-Logix chargers from SOLAR have internal testing mechanisms that check the batter for bad cells, sulfation (this is what happens when a battery is used when not fully charged), or deeply discharged batteries.

Deeply discharged batteries must be charged slower than a mildly-discharged battery in order to achieve full charge. “Deeply discharged” is considered having less than volts or lower than 50% of its capacity. If a battery is so discharged that it has below volts, some battery chargers won’t even recognize that a battery is connected and a second battery must be connected to get the charger to cycle.

Battery Maintenance

Unlike a solid-state charger, the smart charger is also the perfect solution for long-term storage. Over time, batteries will lose their charge naturally. With a maintenance charger connected, the battery will remain fresh during storage so that when it is time to ride, the battery is good to go.

How to choose a charger

You know you need a high-quality battery charger, but you don’t know which one to choose. We have broken them down into several categories that will help you decide exactly what you need. All of the Pro-Logix chargers are capable of charging all types of batteries and each one has the 7-phase maintenance cycle to ensure that the battery it is connected to lasts as long as possible.

For the casual user, the entry-level charger will be sufficient. These are available in and 20-amp versions.

Casual Battery Charger User

The casual user is defined as owning 1-vehicles, living in a moderate climate, where both vehicles are driven daily. Driving your car every day helps maintain the battery, which reduces the need for regular use of a battery charger. The Pro-Logix PL23or PL2320 are perfect for the casual user to provide a maintenance charge for vehicles, personal watercraft, ATVs, and battery-powered lawn equipment when needed. The PL23has 2, 6, and 10-amp charge modes, where the PL2320 steps up the amperage to 20 amps for a faster charge, perfect for larger batteries and heavy-duty batteries such as lawn equipment and PWC/ATVs where you need a full battery in relatively short charge time.

If you have ever needed to get your vehicle started with a discharged battery, then an upgraded charger with Boost Mode is the one for you.

Professional Battery Charger User

If you run a shop or just own a lot of vehicles that use batteries, then you might want to consider a wheeled charger, such as the Pro-Logix PL3730. This charger features 5, 15, 40, and 60 amps in standard charge mode, with a 275-amp boost mode for starting vehicles with completely discharged batteries.

The Pro-Logix PL2520 experience

First, the battery was tested with a voltmeter. 11.7volts at rest, but there was no enough energy stored to crank the engine.

The PL2520 was connected and it recognized the battery and showed the current charge on the display.

The PL2520 has multiple settings for boost mode, voltage and amperage, as well as battery type.

You can choose several variables for the charging rate, voltage and battery type. We put the charger into 10-amp, 12-volt, Standard battery configuration as we had time for an overnight charge. If we needed the battery quickly, 20-amp would be faster, and boost mode would start the car, but this battery needed a full charging cycle as the alternator needs replaced in the car.

The completed battery shows 13.0volts.

The battery was disconnected from the charger and left to rest for an hour to check the residual charge. The voltmeter showed a full 13.0volts resting voltage, and the car has not had any issues starting for week without any additional charging for our tests. After the one-week, the battery has been connected to the charger nightly.

The alternator in the car needs to be replaced, as it is only charging part of the time. This is where a smart charger is very handy. The battery can be connected each night to ensure that the battery stays charged until the alternator can be replaced. Many modern cars use alternator locations that make it extremely difficult to change them, and the car is often down for a long time. This particular vehicle, a 2000 Mercury Cougar, is one of those vehicles. Until the alternator can be replaced, the Pro-Logix Charger will keep the battery from being deeply discharged and ruined, and allow the owner to continue driving it to work. If you have a long commute, this is not a good solution, but if you only have to drive 30 miles a day, it is good stop-gap alternative.

Step Setting the Charger

Set the ampere and voltage that are required for the battery. If you have sufficient time, use the trickle charging method. In that case, you have to set the charger at lower amperage, and the charging will be more effective. If you are in a hurry, you can set the charge at higher amperage.

Hazards of a Frozen Car Battery

Just as your car battery dies due to different reasons, it may also get frozen, if it is exposed to run on a chilling cold environment consistently. The gas from charging expands and may explode with violent force and may spray acid shrapnel to a considerable distance. The gas gets trapped by the ice and cannot vent out. As a result, the battery case may get weakened. Therefore, it is essential for you to know how to deal with frozen battery balance.

Reason for Freezing

If your battery has a lower pH, it will have a lower freezing point. AGM batteries use low pH. If the temperature lowers enough, the content inside may freeze. Usually, batteries are protected from freezing up to -50 degree F. when the nit is charged to 12.to 12.volts. Another reason attributable to freezing is that if the sulfuric acid and distilled water, inside are not properly mixed, the distilled water can be frozen.

Battery Charger for Fuel-Powered Cars

Battery chargers with one or two amperes ratings can maintain battery basic charge levels on parked vehicles to prevent their batteries from becoming totally depleted of energy. These low-powered rechargers are also often used on small garden mowers and tractors. Many car owners carry battery chargers in their vehicles of up to 1or 1amperes for temporarily recharging a depleted car battery.

Auto mechanic shops, commercial vehicle garages or service stations usually have a large enough recharger to charge an auto battery to compete capacity within one or two hours. Just by supplying necessary charging to partially replenish the large count of amperes (hundreds) needed to turn the starter of an internal combustion motor, these chargers can enable drivers to reach the next vehicle service center when batteries become energy-depleted during travel on major roadways or in urban traffic.

Battery Chargers for Electric Vehicles

Battery chargers designed to use for recharging electric vehicle batteries are available from different brands with varying features and qualities. Typical brands with quality ratings are Zivan, Elcon and Quick Charge. The maximum recharging rate of these batteries ranges from kW to 7.kW. Some of these batteries utilize constant voltage to produce continuous current while others make use of algorithm charging curves. Some are designed to be programmed by the individual consumer-user via a CAN port, and others have dial settings for regulating voltage and amperage. Others are actually preset to specific amp-hour, voltage and chemistry of EV battery packs.

Isolated

These chargers do not require any actual connection from the AC electric mains to the batteries getting a recharge. Instead, they operate by a form of inductive charging. Other chargers that are isolated models can be employed in parallel, resulting in less charge time and higher current charging. The EV batteries being recharged have limitations on current intake and must not be overcharged.

Power Factor Correction

PFC battery chargers can lessen battery recharging time because their greatest current delivery is very close to that of an electrical plug.
