For older models (if the battery is accessible)
- Remove the indicator: Gently pry the indicator from the lid using a small flathead screwdriver, working on the sides to avoid breaking it.
- Open the battery compartment: Use the screwdriver to carefully open the plastic case. The compartment is often on the bottom or one side of the unit.
- Replace the battery: Swap the old coin cell battery (likely a CR2032) with a new one, ensuring the positive (+) side is facing the correct way.
- Reassemble: Snap the case back together and then pop the indicator back into the lid.

For newer models (non-replaceable battery)
- Contact Brita customer service: Reach out to Brita to report that your filter indicator has stopped working.
- Request a replacement: Brita will provide a free replacement timer, as the battery is not designed to be user-replaceable.
- Avoid trying to open it: Attempting to force the indicator open to replace the battery can damage it and will likely not be successful, according to this YouTube video.
