Re: RV coach deep cycle batteries
- Hi Roger. I wouldn't go so far as to call it a tough situation, so much
as a situation of running at a speed I can handle as opposed to the
speed the world runs on. I ain't complaining because I'm probably the
most fortunate man on the planet. Most especially fortunate to have
snagged the old Holiday Rambler.
I do have a working generator in the 1978, and a working Onan out of the
Toyota, as well. Might be that will have to be my solution for running
power tools. Once I'm on the road with this thing I'm hoping I'll have
constructed a trailer to pull behind it to carry everything from tools
to extra clothing. I'd thought to mount two golf cart batteries there
once I've got some.
In 1967 I had two golf cart batteries mounted in an aging Nash
Metropolitan and the engine failed somewhere between Port Lavaca and
Houston. Ran the Metro all the way into the next town on the starter
motor and those two golf cart batteries.
The memory of that experience provides me with an abiding respect for

wanting to do something like use an inverter to run power tools for very
long. That will require some serious battery power! You can get a
battery (or batteries) to do that, but they are going to be large. Also
at issue is big batteries require big charging capacity. Your old
voltage converter/charger likely can't handle that load in reasonable
time. Some of them have very little output in the charging circuit.

- Good suggestion Warren. I'm obliged. I had no idea they make 12 volt
golf cart batteries. And the forklift idea's one I'd have never thought
of. Back during my battery warehouse days I did rebuild a good many
locomotive batteries and various ones for other heavy equipment, but
frequently the voltage wasn't confined to 6 and 12 volts.
I haven't looked at industrial/heavy equipment batteries in 50 years,
but it might be they still build them with the tar sealing the top
instead of the one-piece smooth covers. Those big ones were so
expensive it was worth it to the companies to rebuild them rather than
replace them if all that was wrong was a melted strap between the cells,
or a short in one of the cells.
Thanks a bunch. Jack
