WARNING
Batteries have acid that can burn you and gas that can explode.

You can be badly hurt if you are not careful. See Jump Starting on page 10‑92 for tips on working around a battery without getting hurt.

Infrequent Usage: Remove the black, negative (−) cable from the battery to keep the battery from running down.

Extended Storage: Remove the black, negative (−) cable from the battery or use a battery trickle charger.
