How to Choose the Best Car Battery Chargers for Your Needs    

There are many chargers that you can choose from. Let’s review some of the key attributes and determine the features you should look for that best fit your needs.

 Car Battery Charger Type / Battery Compatibility

Going out and buying the first charger you come across isn’t the best method to find the best battery charger! Finding an appropriate charger for the battery type(s) is essential.
It’s true, “batteries” plural – perhaps you own a boat, ATV, motorcycle, lawn tractor or another vehicle or device that uses the starter battery?
A few of the various kinds of car batteries to search for are:

  • Lead-acid
  • Sealed maintenance-free and maintenance-free
  • Deep cycle
  • Gel Cel
  • AGE
  • Wet cell/flooded
  • Valve-regulated Lead-acid
  • Lithium-ion

If you’re likely to have a lead-acid battery in your vehicle already, don’t presume. Examine the underside of your car and think about the amount you’ll have to pay before purchasing.

Automated or Manual?

If you’re a “set it and forget it” type, you’ll require an auto-charger for your car battery. This charger will stop charging when it detects that the battery has reached its maximum capacity.

Manual chargers will continue running until you switch them off. Overcharging the plates could cause damage and stop the battery from charging again.

In the worst-case scenario, the battery could explode. As you can imagine, it is extremely dangerous for you and your vehicle.

Ensure you have an auto-charger (manuals are rarer than they used to be) to ensure the safety of your car’s battery and you!

Voltage Range

Vehicle batteries are available in two voltages, 6V or 12V. Most likely, your daily car has a 12V. Make sure you check before purchasing. Certain older vehicles come with 6V batteries. 6V is also used in tractors and other smaller vehicles.

Certain chargers can handle one voltage or another, and some will charge both. If you’re looking for 12V, you can save dollars by using an individual charger. For the most flexibility, consider an adapter that can handle both voltages.

Amperage (Peak and Voltage for Jump Start)

I’m not even going to attempt to explain amperage in this article. We’re just interested in knowing what’s the best option for us.

You’ll see the peak amps in the list of specs that you’ll find on jump starters and chargers. The more powerful the number, the more draw it can take from your vehicle.

This is essential if you need to start your car instead of charging (some can do both, and we’ll come back to that). This is an excellent indication of the quality of the components within the charger.

If you’re looking to get a huge vehicle to run in colder climates, the charger/jump starter should have the maximum amperage needed that handle a significant draw.

The charging amps vary between .75 amps (often indicated as 750mA) up to 60 amps; for a large jump, you might need more than 275 amps.

Average Charge Time

In essence, In a nutshell, the higher the amps are used, the more rapid the charge will be. But remember that a speedy charge may not be ideal for your vehicle. A smaller vehicle, such as the lawnmower, requires a low-amp charger to complete the task.

An average car battery is around 45 amps/hour. A charger with 10 amps should be recharged from completely exhausted in around 5 to 6 hours. Make sure you know the amp hours before buying a charger and think about how long enough to wait to charge fully.

Of course, the duration required to recharge batteries will differ based on whether you’re charging completely, topping up, or using trickle charging to maintain.

Battery Tester The Feature

If your car isn’t starting, try first to find the most basic reason. Most likely, it’s the battery.

A charger with a tester feature can tell whether the battery carries enough charge. If it appears to have enough power to complete the task, and if not, then the issue must be in another place.

Suppose your charger isn’t equipped with an option to test it. In that case, There are a variety of independent, affordable battery testers for cars available, and we’ve put together a step-by-step guide that will show you how to test your car’s battery.

Security Features

A reliable battery charger should have various security features to protect you and your vehicle. The essential features are the use of insulated clamps and spark-resistant clamps.

Both of these options can help to prevent a potentially dangerous situation.
Other things to think about are:

  • Reverse polarity caution (it’s very easy to attach to the incorrect terminal!)
  • Protection from overload
  • Short circuit protection
  • Over-current protection
  • Protection against over-voltage
  • Protection from overcharges

Jumper Cable Length

A great charger could cause a headache fast if cables can’t reach the terminals.
It would help if you thought about where to place your charger and select the correct length cables.

Certain chargers have extension cables that can be adjusted to meet different requirements.

If you have an existing charger and your cables are short, or if you have an appropriate charger but prefer more cables, you could buy jumper cables on your own.

Jump Start The Feature

The process of slowly charging a battery over time is fine, but only if you’re not rushing to get there!

Some chargers permit the user to use enough electricity to start the engine and get moving. It’s not something you’ll often need however it’s a useful option to have when you have to get into your vehicle.

Trickle The Charge

This is a great feature to include on a charger connected to a frequently used battery.

When the battery has reached the level that it is charged (generally between 85-95 per cent), the charger that comes with that feature can automatically shift to a slow charge, which will bring the battery to 100% and keep it at that level.

With a steady flow of charge through the battery, you can be sure you’ll be able to power up whenever you require it.

This is ideal for golf carts and boats, personal watercraft, yard tractors and many other things.

Battery Diagnostics

Wouldn’t it be wonderful to have your own mechanic available 24/7? The alternative to having, at the very least, with regards to batteries is to have the charger perform a diagnostic test on the battery.

Certain chargers will notify you that your battery isn’t capable of absorbing fully charged.

This is an important thing to keep in mind when you have a draining battery because you left the lights on for too long and can be repaired, but the defective battery is best replaced.

Maintenance Mode

This feature is similar to trickle charging; however, it does not require charging the battery for its initial charge. Instead, Maintenance Mode helps keep your battery fully well-maintained and charged throughout long-term storage.

If you decide to put away your summer toys to be used up or plan to go to a destination for a trip, you can connect your battery to ensure that it’s charged to the max when you require it.


It’s hard to quantify this class or define it precisely. For me, an entertainment system for my home is simple to operate, whereas my relatives are utterly confused. How simply you want to have something is contingent on your prior experience and abilities.

Convenience features, a lot of which I’ve listed as safety options, can help make a car battery charger more user-friendly. Always opt for an automatic charger that switches to trickle mode or is completely off.

If you can go through the instruction manual to determine whether the language is understandable, it’s an excellent start in determining the ease of time you’ll experience operating the machine.

Check online to see whether the manufacturer’s site can be helpful, too.
