Yes, the battery is simple and quick to change and does not require any tools. Before changing your cover, please note whether your Stages Power meter has our original or second generation plastic housing design, as the process to change the battery is slightly different.

Video of Battery Removal


First Generation


To remove the battery:


Rotate the battery door into the "open" position and gently lift outwards to remove the battery door from the unit

If needed, use your finger to tilt the battery and lift it from the compartment. Avoid using sharp tools to remove the battery, as they can cause damage to the electronics within the power meter. 


To install the battery:


1. Insert a brand new CR2032 battery into the battery compartment, with the positive (+)  side facing outward. 

2. Before replacing the door, inspect the o-ring to ensure it is properly sitting into the channel and not twisted, broken, or partially sticking out

3. Re-insert the battery door into the power meter housing aligned with the "open" position

4. Rotate the cover clockwise into the closed position to lock the battery door into place

Right Side Power Meter


To change the battery in a Stages right side power meter, you will need a small Philips screw driver. 

  1. Remove the two screws by turning counter clockwise using a small Philips head screw driver.
  2. For a new meter, pull the plastic tab to remove the battery, then re-install. For existing meters, lightly press on the edge of the battery to pop the battery out, then replace with a new battery with the + (positive) side facing out.
    Note: Do not use any sharp objects to pry out the battery. This can irreparably damage the circuit board inside. 
  3. Carefully re-align the battery door with the housing and re-tighten the screws (clockwise) using the small Philips head screw driver.
