Start-stop batteries are always working.
When stopped at a red light with the brake applied, a start-stop vehicle will shut the engine off. This reduces the amount of time the engine spends idling, in an effort to lower fuel consumption and emissions.
While the engine is shut off, the vehicle is still supplying power to run the entire vehicle electrical system, including heating, air conditioning, heated windows, seats, lights, and all other entertainment systems. When it’s time to go, the brake pedal is released, the engine restarts and the alternator starts recharging the battery.
Start-stop vehicle batteries are considered a hybrid battery designed to handle starting and cycling duties.
In colder climates, these batteries see half the life of a conventional starting battery with even less in warmer climates.
There are two types of start-stop batteries:
Enhanced Flooded Battery (EFB): A basic lead-acid hybrid battery to handle starting and stopping.
Absorbed Glass Mat (AGM): While also designed to handle multi tasking, the enclosed nature and design of AGM batteries eliminate acid stratification battery failure. This is when heavier acid settles to the bottom of the battery and degrades the battery faster. These typically come with a higher cost, but also with a lower failure rate and a longer life.
