Also known R14 or LR14 batteries, C batteries are most often used in medium-drain electrical devices such as toys, flashlights, and other musical appliances to name a few. These batteries are not as popular as AAA or AA type cells, but certainly essential for the right appliances. We offer one of the widest selections of these batteries in the market from leading brands that you know and trust, including Energizer, Duracell, Kodak, Maxell, and everActive. A C battery is shaped as a cylinder typically 50mm (1.97in) in diameter and 26mm (1.03in) high. If you’re looking for quality products at great prices, you’re in the right place.
