LiftMaster K94-37230 7Ah Battery Wire Harness
The LiftMaster K94-37230 is a 7Ah battery wire harness used on select LiftMaster 12VDC gate operators, most commonly RSW12U and RSL12U style systems. The harness connects the backup battery to the operator control system so the battery can charge correctly and provide backup power when needed. It is a practical service part when battery terminals are corroded, the connector has been damaged, the wires have become brittle, or the operator shows battery connection faults. Because RSW and RSL 12VDC systems can vary by model suffix and battery configuration, the original harness, connector style, and parts diagram should be checked before replacement.

Technician Note
K94-37230 is a 7Ah harness for specific 12VDC operator applications. Do not substitute it for larger 33Ah battery harnesses or unrelated LA-series harnesses.
Before Ordering
- Match the manufacturer part number on the original component whenever possible.
- Confirm the operator model, model suffix, and generation before ordering.
- Compare connector style, wire count, battery size, enclosure layout, and harness routing where applicable.
- Use the LiftMaster parts diagram as the final fitment reference when model listings conflict.
- Do not bypass monitored safety devices, reset circuits, interlocks, or fault-protection wiring.
Professional Advisory
Gate operator wiring, battery, reset switch, and enclosure repairs should be completed with power disconnected and with the gate secured from unexpected movement. If the operator has high-voltage wiring, damaged insulation, missing safety devices, water intrusion, or repeated fault conditions, have the system inspected by a qualified gate technician before returning it to service.
