[C320-list] AGM Batteries and Battery Charger

[Robert Tiernay]

I have had 2 lifleine 4d's for about 3 years.  They are great except that
they need to be fully charged (down to 0.5% of capacity 2 amps in my case).
If you don't do that they slowly sulphate up.  I take them down to about 8
amps and go to a marina every couple of weeks (we spend the winters in the
bahamas).  This seems to prevent the sulphation from getting hard.  If you
do some research you'll find lots of people having problems because of the
charging regimen they use.  Lifeline has a manual that you can download -
read it over.  Remember that you can't equalize lifeline batteries
regularly - lifeline used to allow it once a year.  I haven't checked to see
if they have changed that recommendation.

Regarding the charger I have a 100 A Balmar but find that the current drops
very quickly - I would think that a 50A charger would increase the charge
time very little.
