A spent battery must be disposed of properly in accordance with your municipality's waste disposal rules and regulations.
STIHL is committed to the development of products that are environmentally responsible. This commitment does not stop when the product leaves the STIHL dealer. STIHL has partnered with the RBRC (Rechargeable Battery Recycling Corporation) to promote the collection and recycling of spent STIHL Lithium-Ion batteries. The RBRC seal can be found on every STIHL rechargeable battery and indicates that STIHL has prepaid for recycling the battery. The seal has a toll-free phone number (1-800-822-8837) which you can call to obtain the closest battery recycling locations, or you can visit www.call2recycle.org. RBRC has over 30,000 collection sites, and many of our STIHL dealers are enrolled as collection sites.
With use of an approved STIHL charger (AL 100, AL 300, AL 500 - available late 2013), overcharging is not possible.
