Please Note: This part is only available in increments of 5. For example, the 48051 with a rating of 75A has a per leg rating of 37.5A per leg. All Littelfuse–Cole Hersee brand battery isolators have a per leg rating equal to half the alternator rating. A 4-stud battery isolator can be used with older pattern alternators (in this case the 4th stud will remain unconnected), but a 3-stud battery isolator cannot be used with the Delcotron-type alternator.īattery isolators have a ‘per leg’ rating which indicates the maximum current it can deliver to either battery. The newer alternators were first introduced by Delco and are therefore sometimes called ‘Delcotron-type alternators’.

Battery Isolator - 120 A - 1 input / 3 outputs. Battery Isolator - 120 A - 1 input / 2 outputs. will make up for the voltage drop (0.6 V) across the battery isolator. The small 4th stud is for connection to a circuit switched by the ignition switch. Diode Battery Isolators Battery Chargers Retour Quick 12V Battery Chargers. Most alternators on new vehicles have an integral electronic voltage regulator that requires the use of the 4-stud battery isolator. The amp rating of each item is the maximum alternator rating. In addition, both batteries can be charged simultaneously from one source. KKK-A-1822B.įor vehicles with two batteries, these devices electrically isolate the batteries to prevent the battery with the higher charge from draining into that with the lower charge. Diode Battery Isolators allow simultaneous charging of two or more batteries from one alternator. With Schottky diode, to comply with Federal Spec. Argo Diode Battery Isolator - 160AMP - 2 Batteries.
