40 & 60 Amp Select-A-Charge
Programmable chargers. Charges, gel, starting, AGM, and wet deep cycle batteries. % of charge read out.
All the quality features of the regular QSS chargers, plus one touch programming allows these chargers to charge deep cycle, wet starting, gel, and AGM batteries with precision. Also programmable is type of gassing mode, and recycle times when in shut off mode. The 2 digit LED displays percent of charge to complete cycle, and battery voltage. A tricolor LED also follows charge progress. Can be temperature compensated. DC current limiting, and polarity protected.
Float: Regulates the battery voltage at 2.3 volts per cell. Best for starting batteries, and gel's.
Gas & timed shut off: Timer trips at 2.3vpc, gassing threshold. Batteries are allowed to gas to a maximum of 2.55vpc, before shut off. Best for deep cycle batteries.
Gas & float: Timer trips at 2.3vpc, gassing threshold. Batteries are allowed to gas to a maximum of 2.55vpc before dropping into indefinite float of 2.26 volts per cell. Best for deep cycle batteries that may see long periods of inactivity.
AGM: Batteries bulk charge to 2.3vpc, and enter absorption cycle where voltage is allowed to climb to a maximum 2.45vpc before dropping into indefinite float of 2.26vpc.
