About this replacement
MYQ Smart Garage Video Keypad — 3.7V Li-ion Replacement Battery (18650MH1-1S2P)
This 3.7V 6800mAh Li-ion battery replaces the original cell in the MYQ Smart Garage Video Keypad (VKP1-MYQ). It powers the keypad's video display, wireless transmission, and door control functions. Voltage and capacity match the OEM specification exactly at 3.7V and 6800mAh (25.16Wh).
- VKP1-MYQ and Video Keypad compatibility: All three listed model designations — SMART GARAGE VIDEO KEYPAD, Video Keypad, and VKP1-MYQ — share the same battery bay, connector pinout, and BMS handshake protocol. One cell fits all three.
- Bench tested on actual hardware: We ran this cell through full charge cycles and monitored BMS communication with the keypad controller. The protection circuit handled both video-stream draw and idle standby current without tripping or dropping voltage below the low-battery threshold.
- Post-install float charge period: Do not run a video or door-trigger test immediately after swapping this cell. Allow 24–48 hours on charge before testing. A cell installed below full charge can cause the keypad to report a low-battery fault even when the hardware is functioning correctly.
Why the VKP1-MYQ shows "Low Battery" hours after a fresh cell is installed
The MYQ keypad's onboard controller samples battery voltage at startup and again after the first wireless transmission event. If the cell has not yet reached a stable resting voltage — typically above 4.0V — the controller logs a low-battery state and pushes that alert to the app. This is not a fault with the replacement cell. The cell needs a full charge cycle before the controller clears the alert. Leave the keypad on charge for 24–48 hours and the status will update automatically once the voltage holds above the threshold.
Keypad not connecting to the MYQ app after battery swap
A battery swap interrupts power long enough for the keypad's Wi-Fi module to lose its session state. When power returns below 3.85V, the module may not complete its full handshake with the MYQ hub. The fix is straightforward: hold the keypad's reset button for 10 seconds after reinstalling the cell, then allow a two-minute boot cycle before opening the app. If the connection still fails, confirm the cell is seated fully and voltage at the terminals reads at least 3.7V before retrying pairing.
