The battery on me Belkin UPS has packed in and a new one is around 24 pounds inc postage. So I'm wondering, can I hook the ups up to a car battery and will the ups charge it and will the shutdown software still work. Car batteries are only a fiver at me local scrapyard.

:D

Technically you might be able to, but unless you have the specs of both batteries I really wouldn't in case you break the UPS. It probably is a 12V sealed lead acid battery still, but unless you know what you're doing I wouldn't chance it (IMO ;) ).

What's the model number of your UPS, as it might be available somewhere cheaper :thumb:

Its a Belkin 625VA PRO Gold UPS. I did a long search and £24 was the cheapest I found. Here is the Belkin info.

If it would work I can hook up a solar trickle charger aswell. Benifits would be much longer standby time which would be useful.

Thanks.

Thanks Ian thats a pound cheaper than the link I have. Its a bit of a sod as a new UPS can be had for £19.99 or £24.99 with shutdown software.
You can get the same software for free legally on the net. I recon those ups's are made by a firm that deals in really big server ups's as I would swear it is the same picture on both sites.

I'll have a look when I have time. I recon it will be ok on a car battery though and am going to try it out later in the week.
