3.6V Batteries Specifications
Important: Do not use any other type of batteries than the ones specified by BeWhere. Using different kinds of batteries will more than likely result in devices malfunctioning, and will waive our warranty.
B1 and B2 use the same batteries. The difference is that B1 batteries are inserted individually, while B2 have been wrapped up and connected to a battery plug to simplify the replacement process. You can not use B1 batteries in B2 products, and vide-versa.
