A better alternative: mWh
To detail more precisely the performance differences between batteries, the mAh rating—which is the product of current and time—must be enhanced Siemens plc to include voltage. As the product of current, time and voltage, the rating delivers this much-needed measurement improvement.
Returning to the example of NiCd and NiZn cells that are each rated at 800 mAh, the mWh rating reveals the substantial performance difference between the two batteries. With an open circuit voltage of 1.2, the mWh rating of the NiCd cell would be 960 mWh (800mAh x 1.2v). Comparatively, the NiZn cell would have a much higher CR123A lithium battery rating of 1280 mWh (800mAh x 1.6v).
Yes, only by employing the mWh rating does it become evident that there is a significant capacity difference between NiCd and NiZn—a difference that is by the limitations of the mAh rating.
