I have bought this product 2.5 years ago 675VA model
performing well til now no problem faced.this work with manual led indication . it doesn’t have digital indication and we cant get know how much percentage the battery is charged .its automatical cut off after full charging.its has short circuit cut off.
it can handle 3 fans 3 tube lights.and obviously its had over load cutoff, well worked fine when connected over load
we can use as ups and get 8 hours backup continuously for desktop computer by 150mah battery. its very ease to use, just power on leave it. and we have to maintain battery distilled water by its indications on day by day usage consumed .
