I've got an old UPS - just some Chinese 750va which contains a single 12V 7 a/h battery.
I live in a rural town in Cambodia, so obtaining a replacement battery is impossible.
I bought a small motorcycle battery which is 12V 5 a/h and sealed. (Valve-Regulated Lead Acid (VRLA)
Are these safe to use in the current UPS?
Power only goes off a few seconds at a time (a few times a week) - and the ups will only power low voltage devices (eg. router) - so actual current draw will be low.
As its a smaller battery (5 a/h vs original 7/ah) - I'm assuming i won't have any issues of the invertor overheating? As if it does run until its flat, it will run flat quicker than the original battery?
Only thing i'm not sure off is the charging - will the current UPS know when the motorcycle battery is fully charged?
I have the battery in there now, and the ups works - and the unit charge light is on - after about 10 minutes i thought i'd stop charging it check online first to make sure its not going to be a problem. And after a bit of research i could only find posts regarding using larger batteries for extended times.
Hope someone here can help!
