Additional information
For both the automatically and manually started battery tests, the following applies:
The battery test only runs for a short duration to measure the change in voltage over that time
period. Without a minimal amount of load, there will not be a measurement of the change of
voltage over that time period. Without sufficient load, the battery test cannot determine a bad
or weak battery.
As a result of an underload, that is less than 10 % load capacity, the UPS will issue the,
Battery test cancelled UPS Underload.
If the UPS in HE mode, the UPS transfers automatically to Online mode and then the test is
launched. Once the test is complete, the UPS is enabled to transfer back from Online mode to
HE mode.
Battery / UPS storage
All internal batteries for all UPS units are charged to approximately 80 percent of their
capacity prior to shipping. The UPS is shipped with the internal battery connector
disconnected, in order to avoid premature discharge of the battery. The battery is expected to
last at least six (6) to eight (8) months from manufacture, before requiring a recharge of the
battery. Should the UPS be kept in storage after that first recharge, subsequent recharge(s)
should be repeated every six months to eight months. Batteries must be connected before and
disconnected after each recharge. However, it is recommended, the batteries should not be
recharged more than twice. This may limit the overall battery storage period to not more than
24 months.
The recharge period for a battery is 48 hours without any load attached to the UPS.
