Rigsby Posted October 7, 2022 Share Posted October 7, 2022 I have a problem with a Zircon Smooth-i UPS. I believe the battery needs replacing, but basically I've charged it for many hours and when I plug in any item (from a simple phone charger to a PC monitor) it immediately shuts down. Does anyone know of anywhere I can get it looked at in Pattaya as I understand the main service centre is in Bangkok ?? Thanks. Link to comment Share on other sites More sharing options...
Strange Phenomenon Posted February 8, 2023 Share Posted February 8, 2023 A little bit late reply, but the battery is very easy to change in these small UPSes. You just turn i upside down, take a philips screwdriver and open the bottom case. There you find a battery of a standard type and size. Search Lazada or Ebay for a lead-acid battery of the same size, or go to a local electronics warehouse and you will find an exact replacement. I modified mine to get 4x bigger battery so it can last through a little bit longer time. it only powers a router and PoE IP cameras so the power draw is only a few 10's of watts. If you have bigger draw than that you can add a fan to the case. These UPSes are pretty crappy, I found out, because they provide the batteries with 13.98 V float voltage, where it should be maximum 13.8 V, even a bit lower to maximize battery life. So really if I were you I would buy a better UPS with better specs. 1 Link to comment Share on other sites More sharing options...
Rigsby Posted February 8, 2023 Author Share Posted February 8, 2023 Thanks S.P. but having had someone take a look it appears it's a circuit board issue. Link to comment Share on other sites More sharing options...
