BATTERY DISPOSAL
Do not place used batteries in your regular trash.
The nickel-cadmium or nickel metal-hydride batteries must be collected, recycled, or
disposed of in an environmentally-approved manner.
The incineration, landfilling, or mixing of batteries with the municipal solid waste stream is
prohibited by law in most areas.
Return batteries to a federal or state approved battery recycler. This may be where
you purchased the battery or a local seller of automotive batteries.
Contact your local waste management officials for other information regarding the
environmentally sound collection, recycling, and disposal of the batteries.
