I have 2 UPS’ that have expired batteries. The manufacturers want crazy amounts of money to replace them, and a friend recommended I look online to see if I can get them elsewhere. However, the sites all seem so sketchy. Have any of you had good luck with third party battery sites? Obviously a bit nervous about safety.
I’ve used local supplier for years who has spesifically selection for UPS batteries. Even APC ones tend to be pretty standard, just rip the APC stickers off and get the actual battery model number and ask from your local shop for replacement. I got a pair for new-for-me UPS a few weeks ago. Official APC kit would’ve been several hundred euros, the ones I got were ~50 with postage. They might not last quite as long as ‘brand name’ ones and power output is a slightly lower even on spec sheet, but that unit is running at around 15% load anyways, so in my case it doesn’t really matter.
