Each battery has specific characteristics, depending on their chemical composition. Zinc carbon is a cheap battery for basic low-drain devices. Alkaline deliver good, dependable power (usable for any type of device, depending on the alkaline type). Lithium technology is a stable technology for smaller, yet demanding appliances. Zinc Air provide long-lasting, continual power.
Don’t charge an alkaline or zinc-carbon battery, they are not designed to be charged.
