Ted is right on here.  However, be careful about what you're buying - It's
true that many sellers of batteries don't know what they have.  YOU DO NOT
WANT GEL CELL BATTERIES.  These batteries actually have higher internal
resistance than wet cells and are heavier than SLA batteries.  In my
searches I've found that SLA (sealed lead acid) is the most common
nomenclature of the RG Battery that most purveyors understand.  Most do not
know what you mean when you say RG Battery.  So be sure it is truly a SLA
type.  Better yet, just go to DigiKey on the internet and buy the silly
things for about $42.00 each (12V 17 AH).  My info comes from Aeroelectric
also, but I  have talked with and read about many satisfied users of these
things.  I second Ted's advice on overcharging (B&C Specialty regulators and
Crowbars will help here) and on his tip about Bob Nuckolls at
aeroelectric.com.  Subscribe to his publication and you'll get a world of
aviation electrical education for laymen.
