5. Battery Replacement
Please read all of the WARNINGS and CAUTIONS before attempting to service the batteries.
Typical battery life is 3 to 5 years. Environmental factors do affect battery life. High
temperatures, poor utility power, and frequent, short duration discharges have a negative
impact on battery life.
⚫

⚫
Caution -
A battery can present a risk of electrical shock and high short-circuit current.
Contact with any part of a grounded battery can result in electrical shock. The following
precautions should be observed when working on batteries:
a)
Remove watches, rings, or other metal objects.
b)
Use tools with insulated handles.
c)
Wear rubber gloves and boots.
d)
Do not lay tools or metal parts on top of batteries.

Caution -
risk of electric shock. The battery circuit is not isolated from the input voltage.
Hazardous voltages may occur between the battery terminals and the ground. Before
touching, please verify that no voltage is present.
⚫
Please replace the fuse or circuit breaker only with the same type and amperage in order to
avoid fire hazards.
⚫
Only persons are adequately familiar with batteries and with the required precautionary
measures may replace batteries and supervise operations. Unauthorized persons must be
kept well away from the batteries.
⚫
Caution -
Replace batteries with the same number and type as originally installed in the
UPS. These batteries have pressure operated vents. These UPSs contain sealed
non-spillable maintenance-free lead acid batteries.
NOTE:
If there is a power interruption while replacing the batteries, the load will not be backed
up even though the UPS is still on. To replace the batteries with UPS on, please start with step
