Power Sonic® PS–12140

General Description

Power Sonic® PS–12140 battery is rated at 14AH, the PS–12140 is the ideal sealed lead acid battery for your power needs. Part of Power Sonic's 12–volt models, the PS–12140 is a dependable power supply that is relatively maintenance free. These batteries are commonly called “gel–cell” which is incorrect. They are Sealed Led Acid (SLA) batteries. They have been a standard in soaring which is slowly being replaced by the better performing K2 Energy Lithium Iron Phosphate batteries. The primary advantage to the PS–12140 over Lithium Iron Phosphate is lower cost. SLA batteries top performance will last up to a couple of gliding seasons.

Charging

Cycle Applications: Limit initial current to 4.2A. 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 140mA. 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.
