Currently we have only released two models of Ni-Zn battery of AA2500mWh and AAA1000mWh, which is out of question, the most optimal replacement of 1.5V alkaline primary. (mWh / V = mAh)

Rechargeable Nickel Zinc Battery has developed a high-energy density, long-cycle life and low-cost nickel-zinc (NiZn) battery ideal for applications that require high discharge rate capabilities. The technology offers compelling performance advantages, most notably a 30% weight and dimension reduction coupled with higher power and superior low temperature discharge behavior.
