Uninterruptible Power Supply question
I know this isn't exactly OT for this group, but I couldn't find anything in
the comp.* tree that looked right. I have 2 MGE UPS systems Pulsar 14+, that have been sitting around unused for a year. (Long story about life getting in the way...) When last used, they lit up and took a charge fine. I pulled them out today, now that I finally cleaned out and rearranged my computer work area, and wanted to put them back in service. Nada- no lights, no noise, no nothing. I expected the batteries to be flat, but the light for the incoming wall power doesn't even come on. Anybody out there (Jeff W.?) have any idea what is going on? These are from a garage sale, so no docs. I looked on vendor web page, but didn't find anything about dying in storage. Did the batteries (gel packs, like a fire escape light?) crap out completely? They were never dropped, never frozen, etc. Any point in trying to repair or replace the battery packs? Or are new ones so cheap it isn't worth the bother? And just how do I get rid of these, if they are junk? aem sends.... |

I don't remember if the power lights worked or not with bad batteries, but I know the computer did not get any power. |

And to add to the above, if the batteries were sitting around for a year w/o charge, (and were old to begin with), they are probably completely dead. If they are 12 volts, you could take your car battery out and temporarily hook it up to the UPS to see if it would work. Or string together a bunch of flashlight batteries, preferably rechargeable. |

Please do NOT try this unless you really know what you're doing. And if you really knew what you were doing, you'd know enough not to do this. -- |~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~| | Malcolm Hoar "The more I practice, the luckier I get". | | Gary Player. | | http://www.malch.com/ Shpx gur PQN. | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~ |

I am currently using a really old APC UPS to back up my cable modem (I use a laptop) that I scavenged out of a junk pile; the only thing really wrong with it was a dead battery which I matched up exactly to a fire alarm battery which is in it to this day. nate |

IF one decides to use a car battery at least install a fuse, small amperage to protect things if you screw up. |
