I have a 10 year old APC Smart-UPS XL with battery pack, and need new batteries. Looks like I'll be spending $500-700 in batteries.
While shopping around, I noticed a few places selling refurbished UPSes with brand new batteries for pretty good prices. In fact, I could get a more current model with more features for about the same price as replacing the batteries in my existing UPS.
I'm a little bit nervous about buying a refurbished UPS, because I'm not really sure what any particular company means by "refurbished". Who refurbished it? Can I trust that it'll provide factory-spec power protection? Etc. I understand that I won't get a factory warranty or "insurance".
Does anyone have any experience or advice in this matter?
