Q:how can I maintain the device lifetime?
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 20C
3 months at 30C
2 months at 35C
If the UPS was not used for long time, it is suggested to charge it once every 3~5months
