This post isn’t only for you, but also for me. I have roughly sixteen 120V 1300-1500VA UPSes in my basement of various ages. They each take two SLA 12V ~8Ah batteries.
As such, I need to replace those batteries periodically. Being a cheap bastard, I don’t buy the branded APC or CyberPower packs, but go for inexpensive generics from eBay or Amazon. In theory there’s no difference, but in practice some cheap batteries are, well, cheap. I’m attempting to figure out which off-brand brands work best.
Hence I’m going to start logging battery replacements to get an idea of which brand(s) represent the best value and longevity. This will always be a work in progress, because a decent battery should last 3 years. A good one should last 5 or more. Unfortunately I only started labeling them a couple of years ago.
So, uh, stay tuned.
