Garmin Vector 3 battery life probably isn’t top of mind now years after the Garmin Vector 3 pedals were launched and also after Garmin’s new power products were released.
That said, I expect these and other Garmin power pedal battery life numbers to demonstrate excellent shelf life and be worth more second hand than for instance the Favero Assioma pedals. The reason is that since you recharge the Garmin Vector 3 by popping in a new pair of batteries, you’ll never have battery capacity reduction. A new charge is always a full charge. With the Assiomas the battery will eventually wear down…
Actually, I wanted to share my observation in a comment on the Garmin Vector 3 review by my favourite endurance sports technology reviewer, but apparently comments get locked – or at least they didn’t load on my machine.
Garmin Power Pedal Battery Life, long term
Here are the battery durability findings:
| Battery name and Type | Start Date | End Date | Activities | Distance |
| Varta CR1/3N | 15-Sep-2022 | 21-Feb-2023 | 107 | 3368 km |
| Duracell 2L76/CR1/3N/CR11108 | 22-Feb-2023 | 9-Jul-2023 | 100 | 3427 km |
| Duracell 2L76/CR1/3N/CR11108 | 10-Jul-2023 | 5-Dec-2023 | 87 | 2881 km |
| Varta CR1/3N/CR11108 + 2x Duracell LR44 | 7-Dec-2023 | 5-Mar-2024 | 42 | 1440 km |
| Duracell 2L76/CR1/3N/CR11108 | 05-Mar-2024 | 29-Jul-2024 | 75 | 3067 km |
| Duracell 2L76/CR1/3N/CR11108 | 31-Jul-2024 | 14-Dec-2024 | 67 | 3031 km |
| Varta CR1/3N | 16-Dec-2024 |
Besides the hiccup with the LR44s end of 2023, it seems fair to continuously expect Garmin power pedal battery life to last 75-105 workouts. For me, that’s about 3100km on average per set of batteries.
