Battery Model Recommendations for Vector 3/3S or Rally Series Power Pedals

Based on extensive testing, Garmin recommends the following battery types for the Vector™ 3 and Rally™ series power meter systems.

NOTE: Garmin recommends replacing all of the batteries at the same time. Do not mix the battery types.

  • Energizer CR1/3N (2L76), 1 per pedal

    • Most recommended battery type for the Rally series pedals. 

    • Using this type of battery would significantly reduce fretting due to road vibration. 

  • Energizer LR44 (A76BP or A76BPZ), 2 per pedal

  • Energizer SR44 (357 or 303), 2 per pedal

    • SR44 batteries have not been tested for battery life however are expected to last longer than LR44 batteries.

    • SR44 batteries may perform better in cold temperatures.

  • Varta LR44 (V13GA), 2 per pedal


What Is the Expected Battery Life for the Vector 3/3S or Rally Series Power Pedals?

Garmin expects up to 120 hours of battery life before you will need to change your batteries. 

Note the following:

  • Battery life specification is with cycling dynamics enabled and riding in normal riding temperatures. Battery life can be extended if cycling dynamics are disabled.

  • Cold weather riding may reduce battery life.
