Battery replacement for R3W & R3L sensors
Last updated
The TankMate R3L and R3W sensors use 3xAA batteries - Energizer Ultimate Lithium recommended. The sensor has an built in battery monitor to provide battery information through the mobile app. You can see the battery status from the main dashboard screen.
To replace the batteries:
Unscrew the 4 fixing screws that hold the sensor in place
Turn the unit over, and remove the 4 machine screws underneath the unit
Separate the lid from the enclosure base
For cellular sensors - remove the lid carefully to avoid detaching the antenna cable
Turn the sensor off (small slide switch). Remove the old batteries
If a battery clip is fitted - remove this by releasing the sides of the clip with a flat screwdriver
Insert the new batteries, and turn the sensor back on
Put the lid back on, and replace the 4 machine screws - do not overtighten
Fasten the sensor back down onto the tank. Ensure that the lens and o-ring are in place, and there is no moisture between the lens and the sensor base.
Do not use 'heavy duty' type cells in any TankMate sensor
