Life Expectancy of a Lithium-Ion Battery in a Rechargeable Fitness Device

Rechargeable Lithium-ion (Li-ion) batteries will naturally lose some capacity over time due to charge/discharge cycling. All batteries in devices made by Garmin utilizing Li-ion batteries will share this characteristic. Under normal operating conditions, the batteries in Forerunner and Edge devices should have approximately 80% of their original capacity after a few years of frequent charge/discharge cycles.

There are several factors that can accelerate the normal degradation of battery capacity including:

• Exposure to high temperatures

• Leaving the battery completely charged or discharged for long periods of time (anything longer than two weeks.)

When storing the device long-term, it is recommended to partially charge the device (approximately 30 to 50%) and keep it in a cool, dry place. Some devices may require a full charge and discharge cycle before an accurate measure of battery capacity can be made.
