alkaline batteries
Disposable power sources
Alkaline batteries are disposable batteries that use an alkaline electrolyte, typically potassium hydroxide, to generate electrical current.
They power everyday devices like remote controls, flashlights, and toys, and come in standard sizes designated by letters: AA, AAA, C, D.
Alkaline batteries last longer than older carbon-zinc types but cannot be recharged.
