Things Consider When Buying a Car Battery Charger

When looking for a car battery charger, you will find a wide range of models. However, you should know that not all of them will serve your battery, so you must know how to choose the most appropriate one.


Battery Type:

Today, most car battery chargers are capable of charging different types of batteries. However, this is not the case all the time, so you must make sure you choose a compatible model.

Note that there are wet cell, maintenance-free, AGM, gel, or valve regulated (VRLA) batteries. Almost all chargers work with all except gel ones. Batteries of this type generally need a different charger, although chargers for gel batteries can be used for other types of car batteries.


Voltages:

Another critical aspect to consider when looking at models is the charger voltage, as this will tell you what type of battery you can charge depending on the type of vehicle. The most common are 12V car battery chargers, as this is the voltage that most everyday cars operate with. But are not the only ones. You can also find 6 V and 24 V models. The 6V chargers can also be used for motorcycles and other utility vehicles, but you should know that this model will take much longer to charge your car. 24V chargers, meanwhile, are intended for heavy vehicles such as trucks and tractors since they use much more powerful engines.


Battery range:

When choosing a car battery charger, you should also pay attention to the range of batteries they can charge. These devices come with different powers, and depending on your needs, you will have to choose a more or less powerful model.

But how do you know what power you need? For that, you must verify what the specifications of the car battery are. The batteries come with numbers accompanied by the letters AH, which means the capacity in Ampere Hours (Ah) that the battery has. Therefore, if the one you have is 56 Ah, you should buy a charger with a power equal to or greater than this amount. It is recommended that it be slightly higher.


Amps Power:

On the other hand, if you choose a battery charger that is also a starter, you should look at the ampere power it offers. The amperage will tell you what the tool’s starting capacity is, and this way, you will know if it works or not for the type of vehicle you have.


Size and weight:

Another important factor to consider in this type of tool is the size and weight since they are devices that you should always carry in the car. If it has a compact size, you can store it in any space, without representing a problem.


Safety:

The portable car battery charger you choose should have safety features that can help prevent:

  • Battery damage
  • Short circuit protection
  • Reverse polarity
  • Overcharging
  • Overheating.

The vast majority of chargers already include security measures to avoid any accident. But it never hurts to look closely and make sure everything is correct. For example, it is important to see whether a model has a system that prevents short circuits, for example. And do not forget to check if the battery is well protected against external factors and has insulators to prevent it from giving you an electric shock when using it.

Look at the ease of use of the charger:

As you may have already seen, on the market, there are many models to choose from, but not all give the same results. Buy a model that is not very complicated to use, especially if you are not an expert in this type of thing. If you don’t want to complicate your life, it is best to buy a plug and play model.


How does a battery charger work?

The car battery chargers work really simple. These devices consist of an internal battery similar to the one found in cars, but fully charged. It is equipped with two cables, which have a clamp at each end.

These clamps are placed on the battery’s positive and negative terminals to initiate the transfer of energy. In this way, the car will be able to have enough energy for its engine to start.


How to charge a battery with a charger?

It is essential to know how to charge the car battery with these types of chargers. The way to do this may vary depending on the type of charger. However, there is a general process that will work in either case.


These are the basic steps that you should follow:


  • Remove the negative battery cable from the negative terminal and repeat the procedure with the positive cable. Never do it, on the contrary.
  • Verify that the charger is not plugged into an outlet or that the switch is not turned on.
  • Once this is done, you must connect the charger’s positive cable to the positive terminal of the battery.
  • Now connect the negative charging cable of the charger to the negative terminal.
  • The charger is already installed to start charging, so you have to turn it on and select the appropriate configuration (if the model allows adjustments).
  • During the charging process, check the charger frequently to make sure there are no problems. While the charging process continues, do not touch or move the cables.
  • Once the corresponding charging time has passed, you must turn off the charger and unplug it before removing the cables.
  • Disconnect the cables in reverse order as you laid them: negatively charged first, then positive.
  • Reconnect the positive battery cable and then the negative cable.
