Testing, Replacing and Disposing of Batteries
The UPS does not require maintenance by the user. When the batteries expire, they must be replaced
by the appropriate customer service representative. For servicing, replace batteries with the same
type and number of batteries or battery packs that were installed at the factory. For the battery type,
see Table 10.
Disposal of the UPS and batteries should be carried out by a certified disposal company - observe all
local regulations and laws. Exhausted accumulator batteries are classified as harmful toxic waste and
as such the law demands that they be disposed of by an authorized recycling centre.
The Liebert power protection customer service centre is fully equipped to deal with such batteries, in
accordance with the law and with the greatest respect for the environment.
The typical battery life cycle is three to five years, at an ambient temperature of 77°F (25°C), but is
also dependent on the frequency and duration of mains failures.
The battery test (see 4.10.2 - Battery Test) should be run periodically (every 6 to 12 months) to
ascertain the general condition of the batteries and to ensure maximum run time.
