If the storage time is longer than the recharge date, the battery of the UPS unit may drain
completely. In this case, the batteries cannot be recharged any more. The battery is considered
to be damaged and must be replaced.
When to replace a battery
The life time of a UPS battery is heavily affected by a number of factor such as:
Environment temperature
•
Environment humidity
•
Depth of discharge
•
Frequency of discharge, that is how often the UPS switches to battery and back to utility
•
power and how fast
If a UPS battery fails prior to the four year period, then the UPS will issue an according alarm.
The routine self-battery test is meant to alarm if the battery has degraded such that it is
unable to protect the load any longer No percentage of battery load degradation is provided.
Note: Replace a battery only when the UPS informs you to do so.
If the UPS unit issues a battery error / fault then the battery / batteries should be replacedas
soon as possible.
This means is that the battery has failed an UPS battery test, and in case of power failure it
may not provide the estimated backup time.
The battery tests are designed such in order to try to detect a bad battery as soon as it's
possible to distinguish a difference in the battery, but it is impossible to know exactly how bad
the batteries are since battery test is usually run only monthly, or less if the user selects less.
Once the battery is deemed faulty, the run time could change significantly. If the battery is just
starting to get weak in its capacity, the difference in runtime could be small at this time, but if
there some dead cells or dead whole batteries, the run time could be much shorter.
