Non-rechargeable AA/AAA battery includes carbon battery and alkaline battery, carbon battery is much cheaper
than alkaline battery, but alkaline battery is more durable. Electricity volume is 4 times of carbon battery, and their
voltage is 1.5V. They belong to zinc manganese battery.

Ni-CD battery, so Ni-CD battery is rare in the current market, and their voltage is 1.2V.
