Power-Sonic DCG12-50 - Manual (Page 2)

Charging
Cycle Applications: Limit initial current to 15A. Charge until battery voltage (under
charge) reaches 13.90 to 14.20 volts at 68°F (20°C). Hold at 13.90 to 14.20
volts until current drops to under 500mA. 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 13.50
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.
Note : Due to the self-discharge characteristics, 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.
