I agree with you Paul, but more and more repeater sites
are being fitted with computers (for IRLP), so using the
UPS will allow you to power other equipment

Don and all,
I work as a computer IT technician and have used older computer UPS
supplies for a number of different applications. It's easy to hook
up a couple of standard lead-acid batteries from Wal-Mart to these
and gain extra run-time capacity than the original batteries
provided.
But
I know this has been discussed before-
If you go the route of a 12 battery system tied to the power supply- what is
the best way to handle the 9.6v on a Micor repeater?

Tom I use a ASTRON RM 60M-BB (Battery Back Up} and a Optima Battery on My
440 Micor it switches Immediately when You get a Power Failure . You
still use the same device that is used on the Micor for the 9.6, which in my
case is a Little Regulator Board I do have a Panel mount Bird

The problem is… Using a battery on a power supply is that unless you run the
power supply output at around 13.3 to 13.6
of a
volt does make a big difference in battery maintenance.

I am surprised no one has suggested the simple answer with a ups , find one
that does the job and
fit a huge external battery , I have a 2kw unit here with storage which will
run for days (140 kg of
cells), used ups and used traction
As part of my ongoing 12 step program at Junk Enders... I have free
