Of course this bigger size allowed more capacity. The mentioned 750 mAh rating most probably also refers to 5/4 AA. The P100AAS I referred to was a regular AA size battery. Another alternative was size A (not available as a regular consumer battery), which is only 2 mm thicker than AA but it made 1000 mAh possible long before it was available in AA size.

At that time – in regular AA size – with capacities between 900 and 1200 mAh, which was 1,5...2x the usual NiCd rating. Dieter |
