Answer 1

Rechargeable NiMH cells are good for delivering high current that depletes a battery quickly. Devices with motors would fall in this category. Single use alkaline cells have more capacity if discharged slowly, such as in clocks or remote controls. Paying for a rechargeable cells might not be cost-effective. NiMH also self-discharges over time faster.
