Hello,
This may be a really stupid question, but can a gel type marine battery be used in a UPS?
Thanks
I don't think so. Gelcells are different than the sealed lead acid batteries found in UPS's. They have different charging requirements, and will discharge differently than SLAs. Probably best to purchase replacement batteries from the manufacturer...
HTH
Thanks for the info!!
Depending on the vendor of the UPS, you may be able to cheaply replace the original batteries. APC has a program called "ChargeUPS" or somesuch that sends you replacement batteries and allows you to send your old batteries back to them "freight pre-paid" so you don't have to deal with disposing of them properly (which can be a pain in the behind in some areas).
The reason I asked the question was I was looking at buying a used APC 1400 with no battery. It seems shipping for the battery is about as much as the battery itself.
Do you know a particular model of APC that is compatible with CentOS?
Thanks!!

I'm not sure I understand your question. If by "compatible" you mean it will come with software that will work with CentOS so that you can do automated shutdowns and whatnot, I'm really not sure of the status of those tools for Linux in general, and CentOS in particular. That's the only "compatibility" issue I can think of.
Also, I wouldn't buy a used UPS without a battery. You have absolutely no way of knowing whether it works. CompUSA and Staples have recently been selling brand new SmartUPS 1500 units for $199. Even if the used one is FREE, I'd still pay the $199 to get a known good UPS with a warranty.
Cheers,

You can use apcupsd to talk to APC UPSs. Very easy to configure.

...but i think not compatible with all APC models. Check before you buy.

Thanks for all the responses!!
APC sure has a lot of models to choose from. Looks like a unit with USB support may be the way to go. I just want a simple shutdown and restart when power resumes for my server. It would be nice to have a model on the network to shutdown all my PCs (4) on my local network but that may be a little too pricey for me. It's a little fuzzy as to whether each would need a APC card or just need to be running the APC software. How does that work?
Thanks
apcupsd can run in master slave config: one node has a connection to the UPS, the rest is configured as slave. Works well
