I love the way they swell up spectacularly inside certain brands of UPS making them almost impossible to remove. Cruel environment for any SLA.
I'm of two minds on that.
One, you can argue that you want the battery to be returned to a full
SoC as quickly as possible as a second "outage" could follow a
previous one and the UPS would then fail to provide much carryover time.
Two, the UPS vendors want to sell more batteries!
OTOH, UPSs seem to be treated as consumables; folks seem to just
discard the whole unit when the battery needs replacing (because they
likely contact the vendor for the replacement battery and cringe
at the price!).
"Hell, we haven't really NEEDED it much for the past few years...
why don't we just try living without it?"
I wonder what the replacement interval is for the flooded cells they
use (used?) in emergency lighting?  (modern versions seem to have
taken a different -- replaceable? -- route)
