My 0.0000041 BTC:
1) For small facilities, without separate temperature-controlled UPS zones,
the optimum temperature for lead-acid batteries may be the lower bound.
77°F is optimal, with significant reduction in battery life even 15°F above
that. Given that batteries' internal temperature will be higher than
ambient, 80° set point is not stupid. I run cooler, FWIW.
2) Headroom. I try to have documented for each facility the climb in
degrees per hour (determined empirically) as a backup so I know required
response times when AC failure occurs.
