Use boat batteries in UPSes for extended runtime.

and holelly less throwing away batters, APC…. link to ongoing problems.

use spare boat battery (larger one, not starter); get specs for it.
need an inline fuse holder., 5A fuse
20:25pm install as battery in belkin 750va ups; charges at ~0.3A

once stops charge (amps should drop to near 0.0; connect to ups comms software, see if the software things ok

do a rundown test using the metal desk fan; how much run time for it? extrapolte to use as network stack backup

check about hydrogen leaking when charging concern?

would be cool to pull charginer power from a solar panel.
