Will A Battery Maintainer Charge A Dead Battery. I had a dead flat almost new battery from leaving the parking lights on for a week. The maintainer will charge the battery but at a very slow rate.
Most chargers will do this automatically. Boosting your car battery slowly is the best way to extend its life. The way to keep your battery at 100 charge is with a battery maintainer.
They use a system that applies the appropriate amount of current based on the charge level of the battery.
Boosting your car battery slowly is the best way to extend its life. The great thing about battery maintainers is that theyre completely automatic so you can leave them connected for long periods of time. So as the battery reaches full charge the maintainer stops charging the battery. The maintainer will charge the battery but at a very slow rate.
