Your power meter comes with one CR2032 coin cell battery, which allow for up to 800 hours of riding. Replacement CR2032 batteries can be purchased wherever batteries are sold.
1. Twist the cap counterclockwise to remove it. Do not pry the cap.
2. Remove the old battery from the cap by holding the cap by its edges and tapping it against a hard surface.
3. Place the new battery into the cap with the ‘+’ symbol facing the battery cap.
4. Replace the cap and twist it clockwise to secure it.
Tip: Check the condition of the o-ring on the battery cap when replacing your battery. To ensure a watertight seal, keep the o-ring lubricated with silicone grease and replace any o-rings that appear worn or damaged. Find the PRECISION Maintenance Tutorial video at 4iiii. com/docs. Replacement battery covers and o-rings are available from our online store.
Batteries must be disposed of properly, including keeping them away from children. Even used batteries may cause injury if ingested!
