Prevent short circuits
Tape or otherwise isolate exposed terminals when required by the collection program, especially for lithium and 9 V batteries.
Keep types identified
Do not place leaking, swollen or damaged cells into an ordinary mixed collection container. Follow local hazardous-material guidance.
Use local rules
Recycling and disposal requirements vary. Check your municipal or national program and the battery manufacturer’s instructions.
