Charging
Cycle Applications: Limit initial current to 25.0A. Charge until battery voltage
(under charge) reaches 14.4 to 14.7 volts at 68°F (20°C). Hold at 14.4 to 14.7
volts until current drops to under 1.44A. Battery is fully charged under these
conditions, and charger should be disconnected or switched to “float” voltage.
“Float” or “Stand-By” Service: Hold battery across constant voltage source of
13.5 to 13.8 volts continuously. When held at this voltage, the battery will seek its
own current level and maintain itself in a fully charged condition.
Note: Due to the self-discharge characteristics of this type of battery, it is
imperative that they be charged within 6 months of storage, otherwise permanent
loss of capacity might occur as a result of sulfation.
Chargers
Power-Sonic offers a wide range of chargers suitable for batteries up to 100AH.
Please refer to the Charger Selection Guide in our specification sheets for “C-Series
Switch Mode Chargers” and “Transformer Type A and F Series”. Please contact our
Technical department for advice if you have difficulty in locating suitable models.
