Are alkaline batteries better than rechargeable?
An alkaline battery will die much faster at the end of its life, while a rechargeable battery will hang on at a lower voltage for longer, resulting in performance issues such as dimming lights or a clock that can’t keep time.
Why do alkaline batteries eventually stop working?
