12 Volt 12 Amp Lead Acid Battery Charger with Ring Terminals - JAC1212-R

Schauer Fully Automatic Constant Current Electronic Charger charges faster and more accurately than conventional chargers. Charge control is constant current charge to a constant voltage and then to a float standby. The float charge holds the battery at 100% ready state. The charger can be left on indefinitely without worry of undercharge or overcharge.

The JAC Series charger will act as a power supply in conjunction with a battery hook up.

Stage 1: Constant Current Mode (CC)
The charger changes to constant current 12.0 A. When the battery voltage reaches up to 14.6 V, the charging stage changes from (CC) Constant Current to CV (Constant Voltage) mode.

Stage 2: Constant Voltage Mode (CV)
The charger holds the battery at 14.6 and the current slowly reduces. The moment the current reaches 0.5 C (C= Battery Capacity), is called the Switching Point. The Switching Point is one of the great features of this battery charger that it can adjust the current automatically according to the battery capacity. Other chargers without microprocessors are not capable to adjust the current automatically.

Stage 3: Standby Voltage Mode
This charger is also a battery maintainer that maintains the battery voltage at 13.5 V and current slowly reduces to zero. Charger can be left connected indefinitely without harming the battery.
