I have a APC BX800 UPS Unit. The battery is kaput. There are 2 batteries inside wired together in series. I think in series. I want to buy new batteries on ebay. I see several brand x and several OEM APC batteries. The OEM are of course more expensive. My question is about the amp hour ratings. The brand X are from 7 to 9 amp hour ratings. Most of the OEM batteries do not list their amp hour ratings but by asking I have been told that they are 164 amp hour rated. This seems like a hell of a big difference for a battery the same size and about the same weight. What's the difference and is it worth spending over 2 times the amount to replace with OEM batteries except to extend the warentee on the unit.
Thanks
