A:When stored, the ups will self-discharge at a rate that is greatly affected by the ambient temperature. It should therefore be fully charged before being put into storage and if it is to be stored for a long period, it should be recharged periodically to prevent it from losing its original capacity.
As a guide, the ups should not be stored for longer than the periods shown below without being recharged:
6 months at 20°C
3 months at 30°C
2 months at 35°C
If the ups was not used for long time, it is suggested to charge it once every 3~5months
