It's a question of planned vs unplanned interruption. Besides, if you have a generator you should only need a minute until it kicks in.

Our IBM i has been in a data center for several years. Since we no longer
needed the Nfinity UPS for such a small load (Sonicwalls, DNS servers,
switches, etc) we installed a rackmounted Tripp Lite SU1500RTXL2Ua with an
internal battery and an external battery. This gives us just under 2 hours
in a power outage.
Imagine my surprise, now that it's time to replace the batteries, the
internal battery *is* hot swappable, but the external battery is *not* hot
swappable. So we have to shut down the rack to replace the batteries. If
anything, I would have expected the opposite.
It is ironic that replacing the batteries in an "uninterruptible" system
causes an interruption.
