The LiftMaster K41-0102-000 is a 33A battery adapter harness service kit for select LiftMaster INSL24UL and IHSL24UL industrial slide gate operators. This kit is used where the battery backup connection adapters need replacement or where the service diagram calls for the 33A battery adapter harness. Battery harnesses are small parts, but they are important for reliable standby power, charging connection integrity, and proper battery circuit operation. Match the harness to the operator parts diagram and battery system before ordering.
This product page is written for buyers replacing a known LiftMaster part number, not for guessing from appearance alone. Many LiftMaster gate operator parts look similar across generations, so the safest ordering method is to match the part number from the original component, the operator parts diagram, or the model-specific service manual.
Battery backup wiring should be serviced with the operator powered down and batteries disconnected. A trained gate technician should diagnose repeated battery faults, charging faults, or wiring damage.
No. This is a battery adapter harness kit. Batteries must be ordered separately if they are weak or damaged.
It is commonly listed for the INSL24UL and IHSL24UL industrial slide gate operator series.
It may help if the original battery adapters are damaged or loose, but weak batteries, charger issues, wiring damage, and board faults should also be checked.
