9-3 Battery life
■
Battery has a limited life span.
Periodic checks of the lead battery used in the battery unit are required due to the battery
limited lifespan. For the battery checking method, refer to "4-1 Checking the battery".
Battery replacement is recommended before the battery is expired.

Battery life
(The following is expressed based on the battery's trickle life, the service life of a battery
under the condition where low-frequent (once or twice a month) rechargings and
dischargings are performed.)

Basically, the ambient temperature have a high influence on the battery life.

The periodic recharges are required even if the battery is stored.
The battery self-discharges even if the UPS is not used (i.e., leaving the battery not
charged), and it deteriorates the battery. In the worst case, the battery may become
unusable.

<Description>
When the battery is stored at the storage temperature of 25°C, the battery self-discharges
(and the battery level lowers) to approximately 80% over half a year, and to approximately
50% over a year.
Higher the storage temperature is, faster the battery will self-discharge.
