Charging

Cycle Applications: Limit initial current to 2.7A. Charge until battery voltage

(under charge) reaches 4.8 to 5.0 volts at 68°F (20°C). Hold at 4.8 to 5.0 volts

until current drops to under 90mA. Battery is fully charged under these conditions,

and charger should be disconnected or switched to “oat” voltage.

“Float” or “Stand-By” Service: Hold battery across constant voltage source of

4.5 to 4.6 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 specication sheets for “C-Series
Switch Mode Chargers” and “Transformer Type A and F Series”. Please contact our
Technical department for advice if you have difculty in locating suitable models.
