Battery charging

[brad barton]

Scott,
You can spend the rest of the night watching responses to a question on
battery-charging, but...
without getting into actual numbers, here's what I've found in the last two
weeks going through a battery replacement. Traditional flooded batteries can be
charged to just over 14 volts. AGM's can also be charged at or above 14 volts
without fear of overcharging or burning them out or shortening their life. But
gel cell batteries need to be charged to a slightly lower voltage.
Most inverters can be adjusted to account for the differences. The main
advantage of gels and agm's is that their electrolyte media can be sealed to
avoid evaporation, boil out and gassing which can cause corrosion to the battery
terminals and battery compartments. And because they are sealed..and the media
are not purely liquid, the electroyltes can stay in consistent contact with the
plates, etc., they handle heat and vibration better. They're not generally any
more powerful than traditional batteries, they just overcome the heat, vibration
and maintenance issues we don't like.
The main thing is..buy deep cycle house batteries if money permits..no matter
what kind you get. For starting batteries, the more cold-cranking-amps..the
better.Brad Barton 00LXiDFW bbartonwx@...

My (original) battery chargers seem to always be putting out 13.2v. One of the
links posted recenty about batteries seemed to say that the batteries won't be
charged fully unless they get more than 14v put to them. Is this the case? If I
keep using these 13.2v output chargers, are my batts never going to charge?Scott
