Power-Sonic PS-1228 Battery - 12V 2.8AH
The Power-Sonic PS-1228 battery is power-sonic's standard
version of a 12v 2.8ah battery that is completely seal and maintenance free.
PowerSonic PS-1228 Battery Specifications:
Voltage: 12
Capacity: 2.8 amp hour
Terminal: F1
Height (w/terminal): 4.09
Length: 5.24"
Width: 1.30"
Weight: 2.60 Lbs
Cycle Applications: Limit initial current to 840mA. Charge until PS-1228 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 28mA. 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 the PS-1228 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.
