D Rechargeable Batteries Buyer’s Guide

D-size or D battery is quite bigger than its AAA or AA counterparts. D batteries are also bigger than the C dry cells and are available in both primary and rechargeable types. As with all other batteries, these are dry cells in a cylindrical shape with electrical contacts at either end. D rechargeable batteries are well suited for use in flashlights, transmitters, receivers, paper towel dispensers, and more.

D Battery Types

Primary D batteries are either made of Alkaline, Lithium, Zinc Carbon, or Lithium Iron Disulphide (LiFeS2). Of these, the Zinc-Carbon and LiFeS2 are the purely disposable cells. Alkaline and Lithium batteries come in their rechargeable variants such as Lithium-ion or rechargeable Lithium. Other rechargeable varieties include the Nickel Metal Hydride (NiMH), CR123A rechargeable battery and Nickel Cadmium (NiCad) batteries with nominal voltages.

D Battery Dimensions/Specifications

The standard size of a D battery is from 58.0 to 61.50 mm. The diameter ranges between 33.0 mm and 34.20 mm. The D batteries weigh between 160 and 180 grams. Their replacement sizes include Type 373, FR20, 13LF, 13A, 13D, and so on.

These are large cylindrical disposable batteries used for applications that need occasional power. These are typically used in both high drain and low drain applications, although certain industrial D batteries are used for high drain devices.
