Does my UPS work?

Batteries are not cheap of course. A couple webpages gave me the impression that some people just buy a new UPS instead of replacing the battery. That's not a sound plan financially, is it???? Surely a UPS should outlive several batteries, unless there's a lightning strike. The second question is, I've read the instructions but still not sure if the second one works. The instructions are short and don't address my issue APC XS 900 . Does there have to be a load for the Online light to go on? It's off. A 60 watt lightbulb is as good a load as any, right? OTOH, the Building Wiring Fault light is on, probably because somewhere I lost the ground connection, but It's only plugged in for testing. Do I have to plug it in somewhere with a ground to get the Online light to go on? Apparently, the batteries are ok in the one unit. Try putting the 'good' batteries into the other unit so see if it works, before ordering new ones. As others have said, you can get good batteries for cheap on the internet. I've replace mine at least 3 or 4 times over the last 15 or so years and it's still going. When I was 1st gifted with this old AT&T UPS, it wouldn't even pass line current to the output. I borrowed a bunch of 6 volt batteries and connected 4 in series ... this UPS actually uses 24 volts instead of the usual 12 volts. Once the new batteries were connected, it started passing line voltage through. Apparently, on this unit, when the batteries are dead, it tells you by not working at all. What a system! The other answers were valuable and I'm going to reply to them later, but this is the answer I was looking for. Somehow I was suspicious that this could happen, so I'll see if it's happening to me. Yes. First, even the one that was marked Working was like yours. It did nothing when plugged in, but I brought it to the store and he let me try the new battery in it. I had no load and the Online light was off even after I plugged it in, but after I pushed the button, that light flashed green, in a few seconds the yellow self-test light went on, and when that went off, the first light was steady green. Then I took the two batteries I bought and tested the one at home that Paul pointed out had terrible Amazon rattngs. It was dead too, even when plugged in with the old batteries ---- What a crummy design --- but with new ones -- they didnt fit in the case but the wires were long enough -- it acted just like in the previous paragraph. I couldn't hear it hum but my fingers could feel it, including for a minute or two after I turned it off, even though it had only been on for couple minutes. So it takes that long to cool off when it's barely gotten hot I forgot to test it with the lamp, darn, but it probably works. Well there's that transfer issue. It uses a very common size battery, two NP7-12's, which will fit my home burglar alarm too. Air can get in through any of the 8 3-prong holes for electric plugs that are not being used. Or they can go out that way, but that puts all the air near the back of the box. I suppose I should drill a couple holes in the case, maybe 1/2? inch on each side. One inch? |

Also, look on the outside of your unit for a small (maybe 1"x3/8") white bar code label it will have something like BX1300 or XB1300 on it. That number means more than the model number emblazoned on the case of the UPS. There are enough wires around it (it supplies two desktop computers, two monitors, cable modem, sound amplifier, router, tv, and a light) that it will be difficult to access without unplugging everything. As the battery seems to be ok (just over 2 years old), I'll leave it where it is. It has good air flow, and anytime I hear thunder, I turn everything off, including the ups, an unplug it, just to be on the safe side. I trust it to handle short outages, voltage spikes or drops, but not a nearby lightning strike. I've lost a lot of electronic devices due to lightning strikes in the past. I'll keep that in mind for when the battery eventually does go. Regards, Dave Hodgins -- Change nomail.afraid.org to ody.ca to reply by email.

The manual, absolutely, but for replacement batteries, this won't work and the manual won't either. They give the batteries silly names like RBC2, RBC32, Replacement Battery Cartridge #32 Yes, they certainly do give them silly names like RBC2 and RCB32. However, any battery supply house worthy of the name will have cross references to the batteries used in perhaps the widest selling brand of UPS devices. APC and others with "proprietary" numbers count on some people being idiots and unable or unwilling to look past the end of their fingertip as the mouth the words in the owner's manuals. |

So now the expert on Newsgroup posting has taken to replying to his own posts? Wonderful. Take bit of your own "expert" advice and start trimming your posts. We really don't need to read the entire thread over and over. Nor, for that matter, do we need to know the saga of your missing wallet and who, exactly found it and where. Somehow I don't think your idea of drilling 1/2" or 1" holes in the case of your UPS for added ventilation is the brightest idea. To ensure you don't accidentally damage something and not have a working UPS when you need it, I'd suggest drilling those holes while the unit is plugged in. That way you'll know immediately if you damaged something. |

Based on the images etc., it does look like the correct manual. Quite a few of those APC manuals actually cover a multitude of their "models." The best indicator/reference is usually that little bar code label reading "BX1300" or "BS1300" etc. |

I'd guess two 12-volt ones. It's either a single battery, or two in one case, so it looks like one. No, you'll find that it's two batteries, in series, which is APC's style. The two batteries will be joined by a piece of double-sided sticky tape and connected in series using a little jumper (sometimes with an inline fuse in the larger units. As others have mentioned, just buy the appropriate replacement cells. I just "re-batteried" two such units and used some clear 1┬╜" packaging tape to bind them together. Piece of cake! |
