A battery can present a risk of electrical shock and high short-circuit cur-
rent. Contact with any part of a grounded battery can result in electrical
shock. The following precautions should be observed when working on
batteries:
1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
3. Wear rubber gloves and boots.
4. Do not lay tools or metal parts on top of the batteries.
5. Disconnect charging source and loads prior to installing or maintaining
the batteries.
6. Remove battery grounds during installation and maintenance to reduce
likelihood of shock. Remove the connection from ground if any part of
the battery is determined to be grounded. Please note that the battery
grounds mean any battery pole (+/ -) connecting to the ground.
