What Is a Car Battery?
A regular electric car battery is a rechargeable device that supplies your vehicle (and all electronics inside) with the power necessary to start the engine.
Aside from SLI systems (starting lighting and ignition), modern gasoline and diesel engines require a stronger source of electricity. Although SLI models supply the extra power needed for stabilizing and starting the engine of your car, the thing is that the vehicle will always crave for more.
Nowadays, these SLI batteries are generally of lead-acid type with 6 or more cells inside that can provide up to 50-60 Ah when fully charged. Depending on the size of the cells and their number, the amperage may vary. So, you should pay attention to the cold cranking amperes or the amount of current that a battery can deliver. The higher that number is, the more likely you will be able to start the car’s engine at 0°F or even lower temperatures. Additionally, the more electronics your vehicle has, the bigger the battery you look for should be.
To narrow your search, we have picked the most impressive models for our car battery reviews.
To keep any new battery well-maintained and to prevent its self-discharge when the vehicle is not in use, we also recommend one of these trickle charger models. Additionally, it is important to have secondary means of starting your car and any good jump starter will be a great pick for this purpose.
