Yep.....batteries are pretty small in those little UPS and don't have the capacity of the more expensive model UPSes.
My APC even has a popup warning built into it's software to flag a 12 month period.
I have seen the software proclaim full 100% charge with an 18 minute backup time and the battery only last ~30 seconds. That was at 2 years of use. I didn't believe the recommendations either.....until I actually tested the unit.
Every 12 months for me or until I shell out for a bigger UPS.
