The Disposable and Rechargeable Battery Recharger from Popular Mechanics can recharge disposable batteries previously thrown away, saving money and reducing landfill and environmental impact. Capable of recharging a range of battery sizes and types, it features individual battery bays and the capacity to charge up to four batteries simultaneously. Smart sensor technology automatically detects each battery type for a safe, customized charge, and built-in overcharging protection stops charging and automatically and prevents overheating or overcharging.
