My UPS is now 7 years old and I suppose it is time to replace the
lead-acid battery.

My manual, which is now lost, mentioned NOT attempting this.

Any tips from folks who have done this?

Thanks.
Many UPS use a 12 volt 7 amp battery. I have replaced 2 for one friend. $25
to $30.. Google UPS battery when you see what size is needed. WW
