Hi Roy.

At the bottom is a clip for chaarging Gels that I captured from a

   ----- CHARGING.TXT begins -----
Charging the 12V 7AH gel cells:

Cycle Applications: Limit initial current to 1400mA.

Charge until battery voltage (under charge) reaches 14.40 to 14.70
volts at 68 F (20 C).

Hold at 14.40 to 14.70 volts until current drops to approximately 70mA.

Battery is fully charged under these conditions, and charger
should either be disconnected or switched to "float" voltage.

"Float" or "Stand-by Service": Hold battery across
constant voltage
source of 13.50 to 13.80 volts continuously.

When held at this voltage, the battery will seek its own current level
and maintain itself in a fully charged condition.
   ----- CHARGING.TXT ends -----

The current will vary with the size of the battery, but the voltage levels
should be pretty standard across the board.


     Good luck...  M.
