About this item
- DUAL BATTERY MANAGEMENT - Automatically charges a 12 volt auxiliary battery from a single alternator while keeping the starting battery isolated, rated at 125 Amp continuous and 150 Amp peak for vehicles with an auxiliary battery.
- MANUAL OVERRIDE JUMP START - A single push of the override and reset button parallels both batteries so a charged auxiliary battery can crank the engine when the starting battery is low, then returns to automatic charging once the engine starts.
- COMPACT ELECTRONIC DESIGN - Uses electronic switching control technology in a 4 by 4 by 2 inch housing that is smaller and lighter than standard isolators, with surface, firewall, or battery-side mounting and an included mounting bracket
- OVERCURRENT AND SURGE PROTECTED - Built-in surge protection and overcurrent protection guard the isolator and charging system in vehicles with electronic ignition systems, with no voltage drop. For use with lead acid flooded, AGM, and gel batteries.
- WATER RESISTANT IP62 HOUSING - IP62 rated construction makes the isolator suitable for marine installations, and priority charging keeps the starting battery topped up before current is shared with the second battery.
Product Description
The Battery Doctor 20092 is a fully automatic dual battery isolator from WirthCo, built to charge an auxiliary battery from a single alternator while keeping the starting battery isolated. Electronic switching control technology replaces bulky solenoid-style isolators in a compact 4 by 4 by 2 inch housing, and a single push of the override and reset button parallels both batteries so a charged auxiliary battery can be used to jump start the engine. Specifications: Part Number 20092; Voltage 12V; Charging Current 125 Amp continuous, 150 Amp peak; Charge Type Parallel; Control Electronic; Mounting Surface, firewall, or battery side; Voltage Drop None; Built-in surge protection; IP62 water resistance. For use with lead acid batteries (flooded, AGM, gel) and single auxiliary battery systems on negative ground alternator systems. Installation requires 6 AWG or larger wire and a 150 Amp fuse or circuit breaker at the auxiliary battery. Includes mounting bracket. Features include priority charging that fully charges the starting battery before paralleling the auxiliary battery, automatic charging once the starting battery is above 13.4 volts, overcurrent protection against short circuit damage, and surge protection for vehicles with electronic ignition and management systems. Suitable for use at home, in the workplace, on the road, in the campground, and on the water.
