[Public-List] Batteries

Thu Mar 19 07:19:27 PDT 2009

Thanks John for the good info.  I checked the charger and, if memory serves,
it is a True Charge 20 by Star Power with a microprocessor (I guess a macro
processor was too costly).  I will dig up the manual and see if
automatically recognizes different battery types.  I think my best approach
is to read the book (or switch from beer to red wine and buy some oil
lamps).  Has anyone tried a "generator dingy"?

Just to add to my last E-Mail.  Each type of battery need specific
recharging characteristics and for a given size have different Amp hr
capacities.  A wet cell deep cycle battery needs to charge at 14.4v a
standard starting wet cell needs about 13.8v to recharge.  The Gell cells
and AGM batteries also have very different charging voltages.  Make sure
your charger is designed for the batteries you select, a regular charger
will not fully recharge a deep cycle battery. I understand that AGM
batteries have very specific charge characteristics.  sealed batteries are
maintainence free and can be mounted in any position are more expensive and
do not have as much reserve capacity. A while ago while at the Toronto boat
show I asked the sales person from Surrette batteries the question about
using the house batteries for starting purposes, his reply stated that
starting batteries have a thicker internal connecting buss bar as compared
to a deep cycle battery and under heavy starting when using a deep cycle
battery the internal connection could break killing the battery.
