DoorLock DL-2EN 6V Alkaline Compatible Battery 2300mAh

DoorLock DL-2EN — 6V Alkaline Replacement Battery

This is a 6V alkaline replacement battery for DoorLock electronic door locks, carrying the OEM part number DL-2EN. It outputs 2300mAh (13.8Wh) and fits the lock's internal battery compartment at 65.30 x 52.50 x 14.50mm. When the original battery depletes, this unit restores power to the locking motor, keypad, and access control circuitry.

• DoorLock electronic lock compatibility: DoorLock's DL-2EN platform runs a 6V rail that powers both the motor drive and the access control logic from a single cell pack. Swapping to any other voltage or chemistry can confuse the internal electronics or fail to drive the motor under load.
• Bench tested on actual hardware: We cycled this battery through motor-actuation loads on the bench. The output held steady across keypad unlock events and Bluetooth-triggered cycles, with no voltage sag that would cause a mid-cycle motor stall.
• Post-swap access method check: After replacing the battery, test every access method — keypad, Bluetooth, and any keycard — before closing the door. Some DoorLock units run a firmware handshake on first power-up after a battery interruption, and that process must complete before all credential types are accepted.

Why the DoorLock still shows low battery after a fresh DL-2EN install

Some DoorLock units latch a low-battery flag in firmware and don't clear it automatically when new batteries are fitted. The lock reads the flag before it reads the live voltage, so the warning persists even though the cell is at full charge. To clear it, remove the batteries, hold the reset pad (or interior button, depending on model) for five seconds, then reinsert. The lock will re-read the voltage rail and drop the warning once it confirms the supply is above its threshold — typically around 5.4V for a 6V system.

Bluetooth not connecting to the DoorLock app after battery replacement

A full power interruption — even a brief one during battery swap — causes some DoorLock models to drop their Bluetooth pairing state. The lock's radio module re-initialises at startup, and depending on firmware version, it may not automatically re-advertise to previously paired phones. Open the DoorLock app, remove the lock from your paired device list, then put the lock into pairing mode by holding the interior button for three seconds. Re-pair from scratch and confirm the app shows the lock status as connected before testing a remote unlock.
