Is it worth buying a replacement battery for a UPS or better to buy a completely new UPS? I have heard a UPS is never the same after the original battery dies and is replaced.
Is it OK to use a third party after-market replacement battery or should you always go with the original manufacture's replacement battery?
My question is specifically about the APC XS 800 (a small business/home UPS) but I'm interested in your thoughts about UPSs in general.

I've never heard about replacing a battery causing the UPS to never be the same. The only UPS units that I've ever seen are just sealed lead acid batteries that wouldn't cause issues with the UPS electronics unless they weren't specced right (proper voltage and amperage rating). I've used APC and third party batteries and had luck with both. The third party batteries are generally cheaper so that is the way I would go. You don't need to replace the UPS unless there is something inherently wrong with the UPS electronics.
