is it necessarry to charge the battery of ups always??
Answer Posted / sak
it is not necessary to charge the battery always, instead it
should be charged fully once and after discharging you can
charge it again, as nobody knew till what level it is
discharged. so its better to keep the UPS on charge
continously. Anyhow battery last for maximum a year only.
