What to Keep in Mind When Buying a Car Battery Charger?

Selecting the right battery charger depends on your needs. First, you have to ask yourself if you need to fully recharge a dead battery or just keep the battery fully charged? To be clear about the charge of the battery means that you need to fully recharge a discharged battery while maintaining the batteryrequires a simple slow charge.

battery charger for cars
Car battery charger

Most battery chargers perform both functions, but understanding their limits and the amount of time to recharge depends on the size of the battery and the vehicle. So you must take into account the following parameters so that you choose the right charger for you:

  • Voltage: You just need to know the voltage with which your battery works. Almost all cars operate with a 12V system. Unless you’re looking for a multifunctional charger that not only charges your car’s battery but also your utility vehicles, the charger you choose should have 6V of power.
  • Amperage: The higher the amperage, the faster the battery will charge. But charging the battery quickly is not always good. In this case, I recommend a battery charger with automatic detection of voltage and amperage ( smart charger ). This way it is not necessary that you get involved with the configuration. Simply connect it and you’re done.
  • Battery Type: Although today most chargers are capable of charging almost any type of battery, it is important that you make sure you know the type of battery in your car so that you can acquire the right charger for your car. you.
  • Size and weight: This will depend on the space you have to have your charger. Usually, they weigh less than 1 kg, although you can find less portable models that can weigh more than 7 kg. I recommend a small and light model that is easy to have in your trunk.
  • Safety: The portable car battery charger of your choice must-have safety features that can help prevent damage to the battery, short-circuit protection, reverse polarity, overload and overheating.

How to connect car battery charger?

The first thing to identify to connect a charger is the polarities of the cables that are going to be connected to the battery. They are usually identified with the red colour in the positive (+)and black colour in the negative (-)once detected they are connected in the poles of the same symbol located in the battery.

Important Do not connect anything without making sure you know which terminal is which!

How to Use Car Battery Charger?

Although today the different applications and features of many battery chargers can make it harder to use, the general process for setting up a car battery charger is always the same:

  • First, make sure to remove the negative battery cable from the negative terminal and then remove the positive battery cable from the positive terminal.
  • Make sure your charger is not plugged into an outlet and that the ignition switch (if applicable) is in the off position.
  • Connect the positive cable of the charger to the positive terminal.
  • Connect the negative charge cable to the negative terminal.
  • Turn on your charger and mark the appropriate configuration (if applicable).
  • Check the charger frequently during the entire charging process to make sure there are no problems.
  • Do not touch or move any of the charger cables while the charger is in operation.
  • Turn off the charger and unplug it before removing the cables from the battery charger.
  • Disconnect the negative charge cable first.
  • Disconnect the positive charging cable.
  • Reconnect the positive battery cable.
  • Reconnect the negative battery cable.

How long does it take to charge a car battery?

This will depend on many factors such as the capacity and the percentage of dischargethat the battery has. Another important fact is the load speed measured in amperes (A)delivered by the charger at the output.

Where to Buy Car Battery Charger?

There are certainly many places where you can buy a battery charger for your car, I personally recommend that you do it through the internet, specifically by Amazon. And I’ll explain why:

Find lots of models to choose from.

You can find better deals than if you go to a car shop.

Save having to leave home and do searches in different stores besides long queues to pay.

They take the product in a short time to the door of your home.

Virtually all teams have hundreds of buyer reviews.

They have a really good return and a complaints system.


As you can see there are several car battery chargers to choose from, all have advantages and disadvantages. However, I can recommend with confidence the NOCO Genius G3500, the Black and Decker, the CTEK MXS 5.0 and the Suaoki.

While I personally consider that any model of the NOCO Geniusbrand is the best on the market, any of these other units will work well for virtually any user. In summary:

  • Most sold and with more reviews: Black + Decker BDV090
  • Most versatile battery charger: CTEK MXS 5.0
  • Best loader for diagnostics, maintenance and repair: NOCO Genius G3500
  • Best Value for Money: Suaoki

I hope this guide has helped you find the perfect battery charger to meet your needs and that is within your budget.
