Are you tired of having your Ni-Cad batteries that refused to charge and simply die?
So what do you do with them when they die?
Just throw them in the trash - which harms the environment?
Or just take them to a recycling facility for them to be recycled?
Well, here is the best solution, bring your dead batteries back to life that can save you a chunk of change - By zapping them!
