Ryobi manufacturers power tools that come with rechargeable battery packs. The battery packs are infused with Lithium-Ion batteries. Although these batteries are rechargeable, they don't last forever. When the batteries fail to charge or you no longer have a need for the tool that the battery pack goes with, you can recycle the batteries to keep them from ending up in a landfill.
Find a place to recycle your Ryobi battery on Call2Recycle (see Resources). This website has a directory of facilities near or in most communities that will recycle rechargeable batteries. Be sure to verify that the facility recycles Lithium-Ion batteries by calling ahead.
Recycle a Ryobi battery at a major retailer. Retailers such as Lowe's, Best Buy and RadioShack all have recycle kiosks available. All the retailers mentioned above accept the Ryobi power towel battery packs and Lithium-Ion rechargeable batteries inside.
