Chris,
That makes a lot of sense now that I think back. In SoCal, I only recall
1 external event which caused battery intervention (other than the
internal test every 2 weeks of use).
However, here in NW Georgia, all my UPS's have seen numerous external
events since 2004 that required battery intervention. Several of these
were very early morning (nap-time) that did almost fully deplete the
batteries. So far, no lost equipment! So, I'll be happy with a 3yr
replacement cycle for now; but, I will switch to Yuasa batteries!
Best,
Duncan

It depends on usage. If you never have a power failure the batteries

What you should try to do is to make sure they never never NEVER go
under about a 60% charge.
Get a battery under 60% and they never really recover.
