As the title says, I need suggestions on buying a pair of Sealed Lead Rechargeable batteries, the UPS I have is a Spark Power 1200-U, with the following writen on the back: Power 1200VA/720W; I opened it up and found a pair of batteries that has the following specs on them: 6FM7.5 (12V7.5AH/20HR) and I have the following questions:
1) What brand of batteries should I be looking forward to, maybe with a bit of higher spec while maintaining the original dimensions? My target is to safely turn off my PC and prevent data loss during a power out, and not long period of usage, so a max of 5 minutes during gaming or a 15~20 minutes backup while browsing wouldn't hurt, which will be used occasionally I suppose.
2) Recommendation for a shop to buy the batteries from? An exact location of a shop you have personally dealt with before or a personal preference would be useful.
Tagging three well regarded in-house experts: @minitt , @redwan hasan , @Swapnil . Of course, anyone who has any insights on the above queries can contribute for which I'll be looking forward to.
Thank you for taking the time to read this.
