Do not use off the shelf battery chargers, commonly found at Wal-Mart.
These are SMPS conviently located with a 600kHz operating frequency.
Try an LM-317 set as a constant current regulator to trickle the
battery with C/100, Say 1 Amp for a typical Deep Cycle marine battery.

Also look at west mountain the rigblaster people. They have a nice charge
controller that will switch over to back up batteries if you loose power to your
13.8 v supply. I have used one at my base station for six months. It
works great with wet or gell cells. KB1CHU

and the 12 VDC only version (I don't have the model number handy.)

Is it capable of carrying 30 amperes or so?

Lee,
Later in this thread the WestMountain charge controller is referenced...
but.. I wanted to address your question directly.
I have been using a Xantrex C-35 solar charge controller (smart 4 level
charge controller) And 2 pair of big-honkin' diodes to accomplish the same
thing. The diodes were
here are the specs from the website
Specifications
Maximum Voltage:
18 Volts DC
Maximum Current:
40 Amperes
Circuit:
Diode OR-Gate
Diodes:
Two Schottky 80 Ampere, 20 Volt
Voltage Drop:
0.25 Vdc at 1 Ampere0.5 Vdc at 40 Ampere
I will have to check the p/n,but dont think they have the battery
option. Is there any obvious difference in the appearance of the battery
specific units? I will also look for the pot to turn these babys down,
getting tired of cooking batteriesthanks to all,73,Lee

Yes, the battery charge units have a big cast aluminum heat sink on the

There is a simple way to have a reliable backup battery system without a relay.
Try this:
Connect your fused repeater power cable directly to the battery terminals,
without any intervening devices. Connect your power supply to the battery

Well,what I came up with is since the Micor supplies arent
adjustable,was two silicon diodes in the charging circuit. Drops it to
13.5v then added a contactor,normally closed,with a 125vac coil to
connect direct to the batteries during an outage. I will post the
results once implemented. 73,
