Cycle Applications: Limit initial current to 2.4A. 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 80mA. 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
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.
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.

Charging is not
necessary unless
100% of capacity
is required.
Charging before
use is necessary
to help recover
full capacity.
Charge may fail
to restore full
capacity. Do not
let batteries reach
this state.
