Simple, user-friendly D - AAA battery charger. This is one of the "eneloop series" products promoting a pro-environmental clean energy society. Based on its universal design concept this battery charger can hold 12 nickel-metal hydride rechargeable “eneloop” batteries from sizes AAA to D for simultaneous recharging. A simple structure, completely different from existing more complex battery chargers, makes this product extremely user-friendly. It is our desire that this charger will expand the universe of “eneloop” users in homes and businesses and naturally raise their environmental awareness and desire to make environmental contributions.
