How to use a car’s battery charger?

Before moving on to the features and aspects to look into buying an in-car charger, let’s look at how to use a car’s battery charger to get the right benefits.

Electrical devices and gadgets have to be handled with utmost safety and precautions. Here even the tiniest mistake can lead to big problems.

The first thing I like to advise you about is, don’t let the current flow through the charger and then connect it to the charger.

First, connect your charger to the battery, and then turn it on, or you may end up with sparks in the cables. I experienced that myself, and I would not like you to have a similar experience.

But the question here arises is what to connect what. I mean people confuse the clamps.

It is very simple, you need to have a careful look. Connect the positive with the positive and the negative with the negative.

When the connectivity has been successfully achieved, now you can turn the charger on and start charging.

In some chargers and batteries, especially with manual input settings, you might have to follow the individual instruction provided.

Well, these days only intuitive chargers are on the market, and even if it comes with manual input settings, it would not be hard to follow the instruction.

Consumer Reports Car Battery Charger Buying Guide

A car battery charger can’t charge every battery. What if your car’s battery is dead?

But in most cases, when your car’s battery is dead, it is because you forget turning off your headlights all night, or in some other such cases.

But, in most cases, the car’s battery can be charged. And in our list, we have added some mind-blowing car battery charger options that in time juice up your car’s battery.

But the question here is, what features or specs you should look for in a car’s battery charger?

This tiny section is going to help you regarding this.

Size

Car’s battery charger comes in various sizes. Some are good compact tiny, but would not jump start your car, or might take longer to charge up your dead battery.

On the other hand, some are giant, and in no time charge up your dead battery or jump start the car, but at the same time, can take up half of your car’s trunk if you commit to taking them along.

Reverse connectivity Protection

If you are like me, don’t read instructions before connecting the charger or doing other things, and rely on guesswork, chances are that you may end up connecting the wrong cables. If that happens, chances are, you end up with a burnt battery.

But if your charger supports reverse connectivity protection, it will prevent accidental damages from connecting to the wrong end of the battery.

Amperes

Amperes are one of the most important things to look for in a car’s battery charger. It determines the capability. It is important to learn what you will be using the car’s charger for?

If you don’t use your car very often, but don’t want it to be dead in the middle of the destination even when it is left idle for a long time, go with lower ampere chargers.

Lower ampere chargers but can’t jump-start your car especially cold. With the higher ampere chargers, you would not be stranded on the roads.

Many high ampere chargers can easily help you start your car, and make you reach your destination.

If you have a big vehicle and want a higher ampere charger, usually you will get to see is 40-60 amps.

Car jump start

Again, it is not a guarantee that a high ampere car charger will be able to jump-start your car.

But if you buy even a 20 amps car charger with the feature to start the car, you get reassurance that you would not be standard on the roads with a dead battery, roaming here and there to get the help.

Active monitoring of the battery

Yes, most chargers help you learn the total charging percentage. I don’t recommend buying a charger that does not support this feature.

So, the charger activates the battery to allow active monitoring and tell you about yours.

In Some chargers, you will also get overcharging protection, so that you don’t get any issues with your battery.

In some recent models or comprehensive chargers, you get more information about active monitoring. You get the complete information about your car’s battery health.

They also tell you for how long you can rely on the battery, or when to replace or dump the battery.

Repair Mode

I like the idea of adding a repair mode feature to the chargers. The idea behind adding this feature is to help consumers get an extended lifespan, and recharge from home without expensive mechanic trips.

With this feature on car chargers, you get a reduced build-up to prolong battery life.

The voltage of the battery

Before you buy any of the chargers from the list, it is recommended that you check the voltage of the charger.

Different chargers are optimized for different voltages, and maybe the charger you buy doesn’t optimize with your car’s battery.

Usually, the car’s batteries are of 12-Volts, and in our list too, we added 12-volt chargers. And there is very less possibility that your battery runs at a different voltage.

Wrap Up

Car battery chargers prevent you from getting stranded on the roads. With these battery chargers, you not only get your batteries maintained but in some cases, they also come with a jump-start feature.

In this guide, we provided you with some of the best battery chargers. These chargers have been picked after thorough in-depth research.

Most of the models are checked and tested by our team. We also took help from consumer reports, to help you easily pick the most suitable options.

FAQs

What’s the difference between a car battery charger and a jump starter?

Jump starters are usually used to provide your car’s battery with an instant power to let you get out of the pinch.

These are used for emergency purposes, rather than maintenance. They provide a stronger electrical current than chargers and work as a quick fix.

On the other hand, the chargers are like maintenance. They don’t provide instant current to take you out of the pinch but charge the battery with time, and fully charge it to use it organically.

How Many Amps are good for a car’s battery charger?

A general rule of thumb of a good car’s battery charger is, that the fewer amps it got, the better it charges the battery.

But, with a low amp charger, it takes longer to charge the battery, and the one can’t be used for a jump start your car when you are with a dead battery.

So, usually for a Sedan car, a 20-40 amps charger is considered good.

How Long Does It Take To Charge a Battery?

It depends on your car’s battery health, and size. But generally, it can take from 4 to 24 hours.

The average car battery comes with 40 amps, and it takes around 1-1.5 hours to charge the full battery.

For a charger of 2 amp, it takes around 24 hours to recharge a dead battery of 12-Volts.
