Exchanging Batteries/Fan
WARNING
Only qualified service-trained HP personnel should replace or
service the batteries or fan.
The unit comes equipped with sealed, maintenance free, lead-acid batteries. Battery
lifetime is impossible to predict accurately because of the many variables of load, cycling,
and ambient temperature involved. Experience has shown that batteries can be expected
to last three and one-half to five years under normal computer room conditions.
Exchange the batteries in the PowerTrust unit every 3-1/2 to 5 years, in order
to maintain the full 15 minutes of reserve time. All 10 batteries should be
exchanged at the same time.
If the unit is exposed to environmental extremes or frequent discharges, the battery packs
should be replaced more frequently.
Storing battery packs without recharging them periodically may cause damage to the
battery packs, resulting in reduced run time. See “Shipping and Storage Requirements” in
Chapter 2.
