|This article is about the item in Kirby & The Amazing Mirror and Kirby: Planet Robobot. For other uses, see Battery (disambiguation).|
A battery in the Kirby series looks like a standard AA battery in the real world. In Kirby & The Amazing Mirror, it has a yellow casing with orange + and - symbols on it. In Kirby: Planet Robobot, it has a green cylinder with a lightning bolt symbol on it.
Batteries are found as common items scattered across the Mirror World. They power Kirby's Cell Phone, which uses up one battery every time it is used. The phone can hold up to three batteries at a time. If Kirby tries to call the other Kirbys but is interrupted by taking damage, the battery is wasted. If Kirby is KO'd while lacking batteries, one battery is added when he returns.
Batteries in this game work similarly to keys in Kirby's Return to Dream Land and Kirby: Triple Deluxe; in it, it works as a carry item. When Kirby finds a battery, he can pick it up and carry it to a piece of equipment, such as a Swap Chamber or a giant table saw. This is occasionally necessary in order to progress in a stage. In some stages, Kirby must use an electrical ability like Spark or Beam to charge a battery, then plug it in before its charge runs out.
