2.3 BATTERY INSTALLATION

Battery Safety Precautions

Servicing of batteries should be performed or
supervised by personnel knowledgeable of
batteries and the required precautions. Keep
unauthorized personnel away from batteries.
Refer to SECTION 4 - MAINTENANCE for
additional safety precautions regarding
batteries.
When replacing batteries, use the same number
and type of batteries.
CAUTION
Lead-acid batteries contain hazardous
materials. Batteries must be handled,
transported, and recycled or discarded
in accordance with federal, state, and
local regulations. Because lead is a toxic
substance, lead-acid batteries should be
recycled rather than discarded.
Do not dispose of battery or batteries in
a fire. The battery may explode.
Do not open or mutilate the battery or
batteries. Released electrolyte is harmful
to the skin and eyes. It may be toxic.
A battery can present a risk of electrical
shock and high short circuit current.

Battery Storage. The batteries used in the
Battery Cabinet have an excellent charge
retaining characteristic. The batteries can
be stored for up to six months without any
appreciable deterioration. Self-discharge
rate of the batteries is approximately 3% per
month when the batteries are stored in
temperatures of 15OC to 25'C (59°F to 77"F).
If the Battery Cabinet is planned to be
stored for longer than six months, contact
action.
