In their consistent bid to innovate and come out with the best possible products both in terms of reliability and environmental responsibility, Energizer brought out its AA BP-8. In yet another breakthrough in battery technology, the scientists working at Energizer have been able to develop the AA BP-8 as the world's first AA battery made using recycled batteries. If you are worried that recycled batteries would mean it will have a shorter lifespan, we'd like to assure you that you're wrong. The fact that they have successfully managed to incorporate long lasting alkaline in these new batteries means that they will be able to retain a very long run time.
