BR>BR>> FYI, my research has discovered that Lead Acid cells need 1.085x

BR>Nope, each CELL is considered to be 2V, float rate is 1.085x, per commercial
BR>specs (sola) which gives 2.17 V/cell or 13.02 VDC for a 12V "battery". A

 And if you really what to know the condition of the Battery if it is a
 Critical Backup there also needs to be Test Discharge after one of
 those "Equalizing Charges" to compair the Actual AH rating with the
 value assigned by the Manfacturer.
Depending on the AH size of the battery bank it would be done less
frequently then every 6 months.
Interestingly on Super Critical Life saving Medical Devices using NiCAd
batteries I had to do the AH discharge test every three months.
Adn one major manfacturer of Defiburallators shifted from NiCads to Lead
Acid batteries becasue of their Superior Dependibility.
Even then I was required to Replace the batteries every Two years.OR in
the case of the NiCads they, showed less then 85% capacity.
TEST discharges are NOT RECOMMENDED for Lead Acid Gell Cell Batteries.
NOT and amaller Lead Acid battereis.
