First rule of any UPS is to check periodically that the battery is holding
its charge, and to keep the battery charged. My wife bought a UPS when she
bought a PC about 10 years ago, and we never got round to connecting or
testing the UPS for about 18 months, by which time it was out of warranty.

And flatter than a pancake I suspect?

I think the best analogy would be a bucket with a huge hole in the bottom so
it won't hold any water.

Sulphated. Lead acids left flat for 18 months have no chance really.
