Why are rechargeable AA batteries made to be 1.2V while alkalines are 1.5V?
Is there a reason why rechargeable batteries use nickel-metal hydride instead of the same chemistry as alkalines?
Yes, there is. Nickel-metal hydride batteries can be recharged and used multiple times. This makes them a more eco-friendly and cost-effective option in the long run compared to disposable alkaline batteries. Additionally, alkaline batteries tend to leak corrosive chemicals if they are not disposed of properly, which can cause damage to electronics and be harmful to the environment.
