Your Genuine eBike battery is designed for years of maintenance-free use. Following these two rules will ensure that both you and your battery are happy: Charge it! Don’t wait until your battery is completely discharged. We recommend charging before you get down to one bar. Do not charge your battery for more than 24 hours and only charge using the supplied charger. Store it properly! Don’t subject your battery to extreme temperatures or weather. If you won’t be riding for a while, be sure to top off the charge every month or so.
