Batteries and the Environment

end up in an incinerator or landfill, which must be avoided.  
Instead, take the batteries to a Trend Service Agent, your local Trend Stockist or a local 
recycling station.  If necessary contact your local municipality for disposal information.   
The collected batteries will be disposed of properly and/or used for recycling purposes.
