About this replacement
MYQ LiftMaster Wireless Video Keypad — 3.7V Li-ion Replacement Battery (VKP1-MYQ-BT1)
This 3.7V, 6000mAh Li-ion battery replaces the OEM cell in the LiftMaster Wireless Video Keypad (LM-VKP1-LM). It powers the keypad's video capture, motion detection, and wireless access control functions at your garage entry point. When the original cell fails to hold a charge, this replacement restores full operation without any wiring changes.
- LiftMaster VKP1-LM platform fit: The LiftMaster Wireless Video Keypad runs its camera module, IR LEDs, and wireless radio from a single 3.7V Li-ion cell. This replacement matches that voltage rail and connector spec, so the BMS handshake completes correctly on power-up.
- Bench tested on actual hardware: We ran this cell through simulated motion-trigger cycles — camera wake, IR LED burst, video encode, and wireless transmission. The BMS held steady across each combined current spike without tripping into protection mode.
- First-install power cycle requirement: After fitting this battery, perform a full power cycle through the myQ app. The keypad firmware must re-register the new cell before motion events log correctly to the myQ cloud — skipping this step causes missed recordings even when the hardware is working.
Camera going offline in the myQ app after battery swap
Replacing the battery clears the keypad's active session token. The myQ app loses its authenticated connection to the device and shows it as offline even though the battery is charged. This is a firmware state issue, not a hardware fault. Open the myQ app, remove the device, and re-add it through the standard pairing process to restore the connection.
myQ app reporting 0% or incorrect charge percentage after install
The LiftMaster keypad uses a voltage-threshold indicator to estimate charge level — it does not use a fuel gauge IC. A fresh cell sitting at resting voltage can read incorrectly until the firmware calibrates its threshold map. Run the keypad through one full charge and at least one deep discharge before trusting the percentage readout. After that cycle, the indicator should track within a few percent of actual state of charge.
