Good advice. I havent opened mine for awhile so I'm not sure. It is 2 batteries. I figured that having 2 batteries was better in case one went bad.(no clue) I ordered mine from a local Mom and Pop cumputer store, yah I paid more but it is a local business.
I checked out Batteries.com but I didnt see a single battery for the ACP Back(BK) 200 model, only a double type.
I used to live in an area that got severe lightning storms and the power goes out here often, and I was in an urban area(Denver,CO) so I'm a big fan of UPS, but not these cheap power strip protectors. They protect nothing as far I'm concerned.
I'm more concerned against surges/spikes/AC line conditioning over have my computer or stereo staying on for the few minutes then I need to turn it off correctly. I dont have a business that depends on a computer running all the time.
I use a UPS on all my computer and stereo systems, because they are better then a cheap power strip for protection against spikes/surges and etc. IMHO. I have found a few UPSs for cheap at the thrift store. I would hate to blow up a 1000's of dollars and more of computer, video and stereo stuff just because to skimp on a cheap power strip or UPS.
