Ni-MH C 3500mAh  1.2V
These Ni-MH (Nickel Metal Hydride) rechargeable batteries are very high capacity batteries. Ni-MH batteries can be recharged up to 1000 times and they have no memory effect. This results in far greater cost and power efficiency per battery compared to other types of batteries.
