My old UPS died last weekend.

It has voltage protection on 8 outlets and battery backup on 4 of them.

I discovered its cheaper to buy a modern unit than to replace the batteries
in the old one.

Besides better effeciency and more features.

I was thinking of disconnecting the bad batteries, and using the UPS for the
station as a line filter.

This may not work, but I'd appreciate anybody's input.

This thing is so old that it doesn't have any USB ports on it for software.
