Hi Blair,

You must disagree with many others too! I don't claim to be an
expert on the subject and, therefore, must rely on what the experts
say. I am not saying that your particular brand of battery won't
tolerate the lead acid battery charger, just that most all brands of
GEL batteries do not. If you do a Google search for GEL AGM Lead,
you will find over 1000 articles that are similar to the below
reprint from Batterystuff.com. They all seem to agree that GEL
batteries don't like lead acid battery chargers at all, AGM's are
more tolerant but still last longer with the correct charger.

GEL: The gel cell is similar to the AGM style because the
electrolyte is suspended, but different because technically the AGM
battery is still considered to be a wet cell. The electrolyte in a
GEL cell has a silica additive that causes it to set up or stiffen.
The recharge voltages on this type of cell are lower than the other
styles of lead acid battery. THIS IS PROBABLY THE MOST SENSITIVE
CELL IN TERMS OF ADVERSE REACTIONS TO OVER-VOLTAGE CHARGING. Gel
Batteries are best used in VERY DEEP cycle application and may last
a bit longer in hot weather applications. IF THE INCORRECT BATTERY
CHARGER IS USED ON A GEL CELL BATTERYPOOR PERFORMANCE AND PREMATURE
FAILURE IS CERTAIN. Typical absorption voltage range 14.0 to 14.2
volts, typical float voltage range 13.5 to 13.8 volts.
