Best Car Battery Chargers 2019 – Review & Buyer’s Guide

In Reviews by Josh SLeave a Comment

ctek chargerThe most important part of your electric system is the car battery.

A car battery will get a shorter life if you let it stand half-charged a lot.

To make your battery live as long as possible, the best way is to always have your battery charged. Many people drive only short distances and MAX all consumers like fans, seat heats etc and in that case the battery will never get time to get charged by the alternator. The solution to this is to charge your car battery when you are not using it.

Today’s smart car battery chargers give the battery the required charge and you can let it be connected when you want, you do not have to be afraid that you will damage it if you charge it for too long. The chargers have an inbuilt monitoring that will shut off the charging when the car battery is fully charged.

In this article, I will write a review about the best car battery chargers on the market and give you the information you need to buy the right one for your need. I work as a diagnostic technician and I use some of these chargers daily in my work and I have chosen the ones that I’ve tried myself.

Things you should keep in mind before buying a car battery charger.

There are a lot of different things you can look for before you purchase a car battery chargers. Here is a list of the most common things you should look for before your purchase.

Price

The price is always an important part when you should purchase something. Ask yourself what you are going to use it for? How much are you going to use the battery charger? If you are charging your car battery once a year, you will probably not need to purchase the most expensive car battery charger on the market. But if you are going to use it for professional usage at a workshop, for example, you may want to look for a more long-term car battery charger which will last a long time.

Voltage

You should always make sure that you choose the right voltage of the battery charger after your needs. The most cars use 12-volt battery system and you want to make sure that the charger can charge 12 volts. A lot of chargers do have both 6-volt, 12-volt and 24-volt charging, but you should always double check so you choose the right charger for your needs. For example, if you are going to charge both your motorcycle with 6-volt and your car with a 12-volt battery system, you have to find a charger who can do both. Bigger trucks can have 24 volt systems in some cases.

Maintain Charging or fast charging

You do also have to ask yourself if you are going to maintain-charge or use it for fast charging the most of the times. If you are going to maintenance charge it the most, you can choose a car battery charger which charges with lower amperes and have an active charging monitoring. If you are going to charge car batteries fast a lot of times, you should choose one which gives a lot of amperes, and maybe with a jump-start function in sometimes.

Charging Power(Ampere)

This is the same as the subject before almost. Make sure you choose the right Ampere of your needs for your car battery charger. The most chargers can charge with a lot of different ampere rates. But you want to make sure you choose the right for your needs. For example, if you are only going to maintain charge your car battery, you can choose a charger under 5 amperes, while if you want to charge faster, I recommend at least 10 amperes of the charger.

Wall Socket Connector

You do always want to make sure that the car battery charger comes with the right wall socket connector for your country. Different countries use different wall socket connectors and the car battery charger manufacturer location may not be the same as yours. So always make sure that you check this before purchase.

Charging Monitoring

Choosing a car battery charger with an active car battery charging monitoring is important, especially if you are going to maintain charge your car battery a lot and you want to choose a charger with a great monitoring to not damage your car battery in the long run. Normally the CTEK chargers do have a really good monitoring. Because of this, you can almost have the car battery charger connected 24/7, it will do the job for you.

Safety Functions

You do also want to make sure that you choose a car battery charger with safety functions included. One of them is reverse-polarity connection safety, which may save your whole car’s electric system if you accidentally connect the positive terminal to the negative and vice versa. This can actually destroy the whole electric system if the safety function is not included. Another safety function you want is to choose a spark-proof car battery charger when you are connecting the connectors to the car battery. Some car batteries leak battery acid, and if you create a spark when you are connecting the charger, the battery can actually explode.

The last thing you want is to get exploded battery acid in your eyes, because it may result in permanent blindness if you are not washing it way directly. If this happens, wash your eyes and visit a hospital as fast as possible. ALWAYS USE EYE PROTECTION AND OTHER SAFETY PROTECTION WHEN WORKING ON A CAR BATTERY.

You should also check for a charger with overvoltage protection because overvoltage can cause serious damages to your electric system and you really don’t want that if you are charging the car battery with it attached to the vehicle. Overvoltage can damage the system seriously and you may have to replace a lot of different control units, as they are very sensitive to it. This may result in a cost over 10k$ or more.

Jump-Starting functions

If you are going to jump-start your car with a car battery charger, you have to choose one with this function. But the jump starting function in these chargers are not often that strong and if do really need this function, I recommend you to get a Jumpstarter instead for this task. You can find one in our other related articles(Best Jump Starter).

 

FAQ about car battery chargers:

How do I connect and charge my battery?

First, you have to locate your car battery. It is often located under the hood, but in some cars, it can be located in the trunk and under any seat. Some cars do also have two car batteries and if you charge the wrong battery, it won’t make any difference. I recommend checking your repair manual or ask us to find your car battery.

When you have found your battery, you have to check for the positive “+” battery terminal (Often red) and the negative “-” battery terminal (Often Black). There is often a mark on the battery itself which is the positive and negative. If you wire these wrong with an old battery charger, you can damage a lot of parts in your car. New car battery chargers do often have a polarity protection that will save your electronics, but still be very careful.

Connect the red clamp to the positive terminal and the black to the negative and read the manual of the charger how you should start it. Often there are several settings like “Charging” – “Maintenance” and “Recond”. Choose the setting you want to do with your battery.

Some vehicles do have charging/jump starting clamps in the engine bay if the battery is located somewhere else. You can often charge via these clamps, but it’s always better to charge directly on the battery if possible.

Some vehicle manufacturers use a battery monitoring, and you may have to go in with a diagnostic tool to see if the battery is taking charge.

How long time can I charge my battery every time?

With an old charger, you should not charge the battery for too long, depending a lot on the power of the charger. New chargers have active battery monitoring and they will shut off the charging when the battery is fully loaded.

How fast will my battery gets fully charged with these car battery chargers?

It is depending on the power the charger gives out and the size of your battery. Read the manual of the car battery charger. A charger with higher Ampere (A) will charge your battery faster.

Is it best to charge my car battery slow or fast?

Slow is the best to keep a long life for your battery. Usually, I say maximum 4 Ampere if you are maintenance charging your car battery often. You can charge faster if you only do it once because your car battery was low at a specific time and it won’t do much damage to your battery. So if you charge your car battery often ( Several times a week ) you want to keep the Ampere as low as possible for the best charging of your car battery.

AGM batteries should be even slower charger than regular batteries. You can often see on the label of your battery if it’s AGM or not. If you want to learn more about this subject, you can check out our guide How to charge your car battery the best way.

Do I have to fill battery water before charging my car battery?

If your battery allowing you to fill battery water and if the water level is low. You should always fill it with distilled water. Newer batteries are often sealed and you can’t fill them, often because they are AGM batteries. If you want to find the best car batteries you can find it in our batteries review: Car battery review

Can I charge my car battery while it’s connected to the vehicle?

Yes if you have a newer charger with active monitoring and voltage spike protection. Old chargers could give voltage spikes and damage electrics in your car. Newer chargers will not give these voltage spikes and it is harmless to charge your car battery while it’s connected. If you are not sure, always check the manual of your car battery charger and follow their recommendations.

Can I jump start my car with these car chargers?

Small car battery chargers do often not have this function. Bigger chargers can have a “Direct Mode” that allows you to start the car very fast, but these are not always enough. I can recommend you to get a jump starter instead. They are very powerful for their size and the price is not that high. If you are interested in a portable jump starter, you can check out our article: Portable jump starters reviews

How do I know what size (Ampere) of the charger I should buy?

Ask yourself what you are going to use it for. If you are only going to maintenance charge your car battery you will need a maximum 4 Ampere. If you think you are going to use it for both maintenance and fast charging, it is better to buy a large/more powerful car battery charger. A big charger will often have different options and not put out that much ampere if you set the setting for maintenance charging if it has this function.

I think my alternator is not charging properly?

This is a common problem. Charging the battery may help for a short while, but if the alternator is charging low amount of power, the battery will go down again soon. You should always measure with a multimeter on the battery when the engine is at idle. The voltage should be somewhere around 13 – 14.5 volts depending on how many power supplies that are on. If it is charging under 13 volts at idle, check all connectors and ground cables. Check the trouble codes with an OBD2 scanner. You can find different OBD2 scanners on our review page: Diagnostic scanners.
