Need some help with my UPS

[Dorkenstein]

I have an APC 1500 XS Back-Ups and every night in the wee hours it beeps quite frequently. I have put up with it for a long time but now I want to fix it. I live in an old old house and I am sure the wiring is wonky. My questions are: Do I need a replacement battery for it or do I need a new UPS?

If I need a new battery can I use marine batteries or would I still need a new UPS for that? I am also looking at Dansdata's DIY Ups, need to calculate the cost/value. Thanks for any input.

You can use marine batteries.
Requires 2 of them usually in serial to get 24v.

If it beeps its usually either overloaded or the batteries are failing.

I don't see much info on my model. Is it obsolete or was it a bad product?

With your devices plugged into the UPS you can unplug it (the UPS) from the wall socket to see if it keeps everything powered up.
