Best Buy will accept most rechargeable batteries for re-cycling. Today I brought in 3 NIMH receiver batteries and one 3S LIPO battery. The only requirement that Best Buy has is that the batteries be rechargeable. So leave the charging wires on your batteries when you bring them in. Bring them to the service desk.
Good info Herb!
I have several older quad batteries that need to be disposed of and I didn't know where a disposal site was.
Batteries Plus will take them.
