A:Different capacity will have different backup time,with following information,we can choose the most suitable ups to you :
1.What"s the device you plan to use?
2.What"s the working voltage and current?
3.What"s your expected backup time?
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 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
