The capacity of NiCd and NiMH batteries is rated in milliampere hours (mAh). When comparing two different NiCd batteries or two different NiMH batteries, look for the mAh rating. The higher numbers mean potentially more use of an electronic device between charges. Pay attention to the mAh because these vary drastically. Different brands sell batteries with different mAh ratings, but manufacturers also sell batteries of the same brand name, size, and type with different mAh ratings, in some cases very different. This is not to imply that it is bad to buy a battery with a low mAh rating. It is just a warning to be aware of what you are buying and how much you are paying.
