Batteries come in all shapes and sizes. Be sure you know how to dispose of them when they lose their energy.
Household alkaline batteries, which may include flashlight, watch, camera, AAA, AA, C, D and 9V transistor, no longer contain mercury and are no longer considered hazardous. You can dispose of them in household trash.
Rechargeable batteries typically contain heavy metals that are considered hazardous and should be e-cycled.
Batteries in self-balancing scooters can catch fire, so remove them from the unit before disposing of the scooter. Contact your local battery retailer or electronic recycler for information on acceptance of the battery pack.
