D Batteries

D batteries are a type of cylindrical dry cell battery commonly used in larger devices that require higher levels of power output. D batteries are often used in flashlights, toys, and portable radios, among other things. The size of a D battery is approximately 33.2 mm in diameter and 61.5 mm in length, making it larger than the more commonly used AA and AAA batteries.

An advantage of D batteries is their relatively long shelf life. They can typically last for several years if stored properly, which makes them a good option for emergency supplies or other situations where batteries may be needed but not used for an extended period of time.

Rechargeable D batteries are also available in different chemistries, including Nickel-Cadmium (NiCd), Nickel-Metal Hydride (NiMH), and Lithium Ion (Li-Ion). D rechargeable batteries provide a sustainable and cost-effective option for powering devices that require this battery size. An advantage of rechargeable D batteries is their relatively low self-discharge rate. This means they can hold their charge for longer periods of time compared to some other rechargeable battery types, making them ideal for use in emergency devices like flashlights or radios.

Duracell is a well-known brand that offers Alkaline D batteries. They are known for their long-lasting power and reliability. Energizer is another popular brand that offers D batteries. They offer both Alkaline and rechargeable D batteries, and their products are known for their high-quality and long-lasting performance.
