A sticker that extend your mobile’s battery life? It may sound unlikely, but that’s what BatMax claims to have come up with. The sticker is compatible with all mobiles and can extend your battery’s life to up to twice as long, we’re told. It’s based on IonXR "nanoceramic material" whatever that may be. This slows down the rate at which batteries lose their juice-storing capacity, extends power from each charge and also speeds up the charging time. It will work on pretty much any type of battery and can be used on older batteries to rejuvinate them. It elimates battery "memory" effect and regulates the current supplied from power sources to protect against variations. It costs $12.95.
