What type of batteries are used in cars?

Batteries are either conventional lead-acid or the more advanced AGM design mentioned earlier. Most cars on the road today use conventional batteries, but some models use AGM batteries that are highly spill resistant and better able to handle repeated discharging and recharging, as occurs in cars that have engine stop-start systems to improve fuel economy. Because charging systems are often optimized for the battery type, AAA recommends always replacing a battery with the same type that came in the car from the factory.

What is 650 CCA?

The cold cranking amps rating, for example 650 CCA, is an industry standard measure of how much electrical power a battery can provide at zero degrees Fahrenheit. Never confuse this rating with “cranking amps” (CA), a rating based on an easier test that produces inflated numbers. Some import automakers state battery power requirements using an amp-hour rating, for example 78 Ah. This rating is based on the number of minutes a battery can provide a specified level of electrical current, typically 20 amperes.

How long do car batteries last?

There is no simple answer to the question of how long a car battery will last, but it is possible to offer some generalizations based on decades of industry experience.

What is the last factor that affects battery life?

Vibration. The last key factor in battery life is vibration, which causes physical breakdown of internal battery parts. To minimize the effects of vibration, special hold down hardware secures batteries in place and prevents them from moving about. Missing or loose hold downs can significantly shorten battery life.

Why select a battery with the same group number as the original equipment battery?
