battery packs.
z Do not dispose of batteries in a fire. The batteries may explode.
z
Do not open or damage batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
z A battery can present a risk of electrical shock and high short-circuit current. The
following precautions should be observed 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.
−
Disconnect charging source prior to connecting or disconnecting battery
terminals.

Determine if battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded battery can
result in electrical shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not having a grounded supply circuit).
