The LiftMaster K-002D0776 Charging Circuit Board Kit is an OEM replacement charger board engineered for LiftMaster gate operators that use onboard battery backup. Designed to keep backup batteries properly maintained, this charging circuit regulates and replenishes battery power so the operator can continue to run during an AC power outage. It’s a common service part for select LiftMaster swing and slide gate systems used in residential and light commercial applications. Buyers often search for it as K-002D0776 or K002D0776 when restoring charging functionality on compatible Elite-series gate operators.
This kit replaces the original charger PCB inside the operator housing and connects to the existing control board and battery leads to provide automatic charging and float maintenance for the specified batteries. Installation typically involves mounting the board in the designated location and transferring the factory harnesses; always disconnect AC power and the batteries before servicing, observe correct polarity, and follow the model-specific wiring diagram in your operator’s manual. Compatibility is model dependent; consult your LiftMaster parts list or manual to confirm K-002D0776 is the correct charging circuit board for your unit. No programming is generally required once installed—the board automatically manages battery charging per the operator’s design to help ensure reliable backup performance.
