Why are rechargeable AA batteries made to be 1.2V while alkalines are 1.5V?
Can you explain that a little further?
Sure! Alkaline batteries use a chemical reaction between zinc and manganese dioxide to produce electrical energy. This reaction has a higher voltage output, at 1.5 volts per cell. Rechargeable batteries, on the other hand, use a different chemistry called nickel-metal hydride which has a lower voltage output of around 1.2 volts per cell.
