And only $217.00 while current supplies last!

I bought a brand new battery for $39.95 battery two years ago for
testing the R.G. Still works fine. I charge with a 40 year old 1 amp
trickle charger with a selenium rectifier. The R.G. breaker is 30 amps.
I turn on the master every few day, so as to maintain pressure in the
R.G. About every 2 weeks the pump comes on for 1/4 to 1/2 of a second.
For a month and a half it was coming on almost every day, until I
discovered a leeking fitting. Only required a 1/4 turn to fix. 

I plan to use it until it can not longer hold a charge for engine start.
Most aircraft electrical system have alternators of sufficient output to
provide full electrical demand. Turn off the MASTER. All this does is
disconnect the battery from the electrical system, not the output of the 
alternator.

The RMI Monitor has a digital Amp Meter, which shows the electrial
demand from alternator as well as a low battery voltage alarm. The
Monitor also has it's own battery which can be used at any time, which
it keeps charged.

A number of years ago I had taken the battery out of my car to test it.
It was dead. I saw no need to put it back in, instead put it in the
trunk, jump started the car, and drove off to get a new one. It was a
hot day, I put the A.C. with full fan. As I pulled into parking lot, it 
dawned on me, so I put on the headlights and finially the fan started 
slowing down. I put a new battery in at the parking lot, started the
car, came back home. Why stand in line waiting for the new one to be
installed.
