Always plug battery charger into scooter before plugging into electrical wall outlet. When charging is complete unplug charger from wall outlet before unplugging from scooter or bike. 2. To get the most life out of your scooter’s batteries, recharge them immediately after every ride, even very small rides. Leaving a scooter battery in a partially discharged state for any amount of time lowers the useful life of the battery. 3. When a scooter is in storage, recharge the batteries at least every 3 months. The Amperage of the battery charger may be decreased for longer battery life, or increased for a quicker recharge time.
