Ni-Cd batteries can be removed before disposal in the local recycling center. Unfortunately, there is no spare battery can be arranged. Too bad, like me, you have to buy a replacement. To remove the batteries, unscrew the base with small valve on the back of the cradle mounted in a vertical position, remove the battery and leverage private transport batteries. 1 comments: It is a Ni-cd battery that can’t be disposed of in a recycling center. 1 comment:”]
