All batteries loses efficiency over time. To indicate this efficiency we use the term cycles. One cycle is the same as fully using the battery from 100% to 0%. To benchmark the amount of cycles a battery can handle, 80% is set as the maximum amount of battery degradation. For example, if you charge the Wattsun three times a week, you’ll only reach a 20% loss of capacity after 5 years. This means you can still fully utilize the power of the Wattsun, although the battery capacity will have slightly decreased.
