PerfPower Corporation provides PerfPower™ Go Green alkaline batteries with a free recycling initiative. These recyclable batteries are made with no lead, no mercury and no cadmium and all packaging is made with recycled materials. The batteries also come with a performance guarantee to show you that although we are created a more eco conscious product, performance is not compromised. The way it works is quite simple: you buy and use PerfPower™ Go Green batteries, then register on www.iRecycled.com, and when you have enough batteries to fill a USPS flat-rate shipping box, you print out a label and have it shipped through USPS. Absolutely free! We pay for the shipping and recycling and you can rest easy, knowing you did the right thing.
