AA Batteries

Types of AA Batteries

Disposable alkaline batteries

• Significantly cheaper
• Can only be used once - cannot be recharged
• Remain fully usable even in high temperatures over 50 °C

Rechargeable batteries

• NiMH cells are the most common (nickel-metal hydride)
• For NiMH cells the service life is about 500 charging cycles, for Li-Ion batteries it's up to 1000 cycles
• Unlike alkaline batteries, they can be recharged and used again
• The voltage for rechargeable NiMH batteries is 1.2V, for Li-Ion batteries 3.6V
