I had not got this auspicious opportunity to change the UPS battery in these 5 yrs (till it was working), yup, its a good reliability..
But, still do check for APC, i knw u wnt regret it,
UPSes are expected to work for a good 5-6 years.. on a single battery.. porvided u follow sum instructions to make its life worth living.. say,
1.) PRevent it from dust, i.e cover it with a cloth once u hv finished ur work on PC.
2.) ppl say its a good idea for a UPS to be ON for eternity, but tats a bad bad habit, PLEASE for god's sake and urs too
plz SWITCH OFF the UPS once u hv done with ur work.
Cheers n e-peace....
