While D cell batteries aren’t as common as they used to be — I remember every Christmas morning there would be some toy that would beed about a dozen of them! — if you need them, then using rechargeable batteries makes sense given their size and cost.
These batteries have a built-in micro USB port, allowing them to be recharged from any USB port and making them super convenient. You just have to plug them in, leave them to charge, and in a couple of hours you come back to fully-charged batteries.
These are ideal for powering toys, radios, flashlights, and anything else that draws its power from D cell batteries..
