Heat halves UPS battery life
Sealed lead acid UPS batteries are rated at 77°F. Roughly every 15°F above that halves their life, so a warm comms cupboard quietly shortens runtime.

Hurricane season runs from 1 June to 30 November. The firms that recover fastest decide in May what shuts down, what keeps running and how staff will work if the office is closed.
UPS capacity and battery health checked, generator integration tested and runtime confirmed against real load.
Automated shutdown configured so systems power down safely when batteries run low.
Server room temperature and humidity monitored, with alerts to someone who can act.
Backups offsite and staff able to work securely from elsewhere if the office is closed.
Tasks and owners for the run up to a storm and the return afterwards.
A recovery test before the season starts, with results on record.
Power, cooling and backups assessed in spring.
Batteries, configuration and gaps addressed.
Shutdown and recovery tested.
Staff and management briefed on the plan.

In April or May, so fixes are in place before 1 June.
Usually, yes, in a planned order once data is replicated offsite. The plan should say when and who decides.
It depends on the load and battery age. We measure it rather than trusting the label.
