[C320-list] Battery Charging

[Warren Updike]

A "properly operating" 3-stage charger should not cause a problem to your 
batteries.  The operative word here is "properly."  Can't speak for the Pro 
Mariner in terms of it's record.  However, remember it is a 'system' and 
things function in an inter-related fashion.

If your batteries are not in good shape, that is to say they won't accept a 
full charge, the charger may never go into float mode and continue to push a 
higher voltage.  The result is an over charge that boils away the water 
while never getting the battery up to full charge.  Have your batteries 
tested with a load tester by someone familiar with it's use.  It's the best 
way to determine the condition of the batteries.  I'm sure many people have 
cursed their charger when the problem lies with the batteries.

I've heard that one should not keep boat batteries on charge for extended 
periods. That is, when docked in my slip (which is most of the time), should 
I leave the charger on continuously or leave it off and only charge once a 
month (or so)? The charger is a 3 step type which ends up in "float" mode at 
about 13.5 volts. Also, the charge is a Pro Mariner 1230 which seems to have 
a bad reputation. Any advice?
