C And D Sized Rechargeable Batteries
Find out where to buy true high capacity C and D sized cells
home > storage | shopping | energy efficiencyThough nowhere nearly as common as AA and AAA rechargeable cells, C and D sized cells are still found in many children's toys, torches, and portable radios/stereos.
Rather than manufacturing real C and D sized rechargable cells, most manufacturers simply use their AA rechargeable cell to give the power, and then pad it out to the size of a either a C or a D cell. If for example, you look at the UniRoss Hybrio range of rechargeables, the AA, C, and D cells all have the exact same capacity - 2,100 mAh - yet the C and D cells cost almost double the price of the AA cells!
AA to C and D Battery Adapters
Rather than paying double for the same battery (with a bit of padding), AND having to buy an expensive C or D sized battery charger, it makes far more sense to purchase your own relatively cheap high capacity AA rechargables together with reusable battery adapters such as these pictured below:
An AA rechargeable cell is simply clicked into the plastic C or D sized holder, and inserted into the appliance to be powered.
High Capacity C and D Sized Rechargeable Batteries

Although difficult to find, high capacity rechargeable C and D sized cells are available. At the time of writing (July 2008) 5,500 mAh C-sized, and 11,000 mAh D-sized rechargeable cells were on sale on eBay. In the case of the D cells, at 11,000 mAh they offered a whopping five times the storage capacity of most rechargeable D cells sold in the UK.
