How to choose the right battery charger for your car

Normally when your car starts, the reserved power from the car battery will allow the engine to start. But when that reserved power is enough or just ran out then it’s time for the charger to do its job. Depends on your car, here is a few factors that you should consider when you’re choosing your car battery charger.

Battery Charger or Jump Starter

First let me explain, battery charger work just like any other charger. It provides power for the battery but this process takes time and you’ll have to wait until your battery has enough power to start the engine. The jump starter works a little different, it allows your car to start even when the battery runs out. That’s why it’s called the jump starter.

So depends on your situations, if you want to start the car as quickly as possible then you’d probably need a jump starter. But I only recommend using it in a critical situation. If you have time, you should recharge your battery properly to ensure the battery’s life. Your battery needs to be fully charged before you use it. Some may say that the battery can be recharged when your car is running, this is true but the car won’t be fully charged since you also use the power when driving. Plus, the power current when you’re driving isn’t stable and it could cause your battery to wear out.

Battery Size and Voltage

Then you need to choose charger bases on your battery status. How much capacity, power current, and voltage is the key factors when choosing a car battery charger. Your charger must provide enough power in a certain amount of time so the charging can have the most effect.

Plus, the current must match your battery so there shouldn’t be any problems while charging.

Battery chemistry

It basically means what are the components of your battery. Most batteries are lead-acid batteries which have plates that are dipped in an acid bath. Inside the bath, a chemistry reaction between the plates will happen when the power cable is a plugin. The negative ions from one plate will move to the other. Thus, create power to recharge your battery. There are a few common battery chemistry types, AGM, Gel Cell, or Deep Cycle. Not all charges are designed to deal with all types of battery chemistry so you should carefully examine your battery before buying a charger. Make sure there are no problems between your charger and the battery.

Additional features


Here are some features that your charger need to have to ensure the safety when charging.

Auto discharge

This is one of the features that I recommend driver equip on their car battery charger. Basically, it turns the charger off or to maintenance charge mode to avoid overcharge your battery which could avoid serious battery problems.

Warning features

Your charger should have the ability to gives you a warning when the wrong power cable is hooked in or the power source isn’t stable. This is a life-saving feature that I always recommend my client to equip on their charger.

Battery diagnostic

Over time, your battery could have a surface of sulfate that was build up due to the chemistry reaction between the plates. Too much of these means that your battery has gone bad and it’s time to fill in new acid. Some charger can detect your battery status without opening it up.

Solar charge

It may seem unnecessary in normal condition but the solar charge can be essential sometimes. So you should buy a charger that has an additional solar charge feature on it just in case.
