Battery. Never disconnect the DC connectors under load.
A battery can also present risk of high short-circuit current. Observe the following precautions when
working on batteries:
Remove watches, rings, or other metal objects.
Use tools with insulated handles.
Wear rubber gloves and boots.
Do not lay tools or metal parts on top of batteries.
Risk of electric shock. Risk of fire. Do not work alone. Someone should be in the range of your voice
