Why are rechargeable AA batteries made to be 1.2V while alkalines are 1.5V?
That's interesting. Are there other types of rechargeable batteries besides nickel-metal hydride?
Yes, there are. Lithium-ion batteries are also commonly used in rechargeable devices due to their high energy density and longer lifespan compared to nickel-metal hydride batteries. However, they have a higher cost and can be hazardous if they are not handled properly.
