My table of typical battery capacities gave a wrong value for the
Alkaline AA cell.
The table should have read

All values in mAH

>Alkaline    AA        2250
>Alkaline    C           7500
>Alkaline D            15000
>NiCd AA                 500
>NiCd C                1800
>NiCd D                 4000
>
>Your mileage WILL vary.
