The Panasonic lithium-ion battery cells will provide approximately 800 “full” charge cycles before a replacement is recommended. A full cycle is considered one complete discharge, so if you only discharge the battery halfway before recharging normally, your battery will last for twice as many trips! You can discharge the battery 50% and charge it back up to 100% twice to equal one complete charge cycle.
The longevity of the battery will last will vary depending on each person's use case, but the average lifespan we are seeing for our batteries is about 5 years. A very heavy user who drains a full battery every day will see about 2.5 years of life from their battery while a casual user's battery can last closer to 6-7 years.
This is the same for all of our models.
