Subject: Re: Aux battery solution??!!!
Rob:
After a couple of trips (the last one being 2,500 miles and 12 days) I can
say that the batteries seem to be working really well. I have a problem
that I need to figure out, and that is that if I run the fridge on 12v while
making a long drive (4 hrs+) the aux. batteries end up with less of a charge
that when I started. This is despite the fact that they are receiving a
good charge if the fridge is NOT turned on.
Anyway, it is a wiring problem I need to sort out (unrelated to the
batteries themselves)....
The batteries are from East Penn Manufacturing
http://www.eastpenn-deka.com
I have actually received a response from them by e-mailing to
eastpenn@eastpenn-deka.com
The 8GU1H batteries are 12 volts each, and are rated as the following:
CCA@0 degrees F - 215
CA@ 32 degrees F - 310
Res Capacity - 44
Minutes to discharge at 5 amps - 325; 8 amps - 190; 15 amps - 90; 25 amps -
47
AH capacity @ 20 hour rate: 31.6
weight - 24.2 lbs.
size: 8-5/16L x 5-1/8w x 7-1/4h
Keep in mind that with my set-up, these ratings are basically doubles (for
reserve capacity)
I have them rigged in parallel, with a marine trickle charger/maintainer
plugged into the refrigerator socket so that they get a good charge when on
shore power.
If anyone wants a copy of the spec sheet, I can fax it to them - just e-mail
me your fax number.
