D Batteries


What is a D Battery?

The D battery (or R20 battery) is a dry cell classified by its 61.5mm x 33mm dimensions. They boast very large capacities upwards of 20,000mah and were often used in flashlights, but today are used more for megaphones, radios, and devices that need long-term power.

Why Buy D Batteries?

D batteries can be found in a wide variety of applications, including high-drain devices like flashlights and lanterns. These household batteries are also often used in industrial appliances, radio receivers, children's toys, and even in some safety systems. But what makes a D battery different than AA and AAA cells? When comparing different sizes of alkaline cells, you will quickly see that they all have the same 1.5 voltage. So why would anyone choose the larger and heavier D battery over the more petite AAA? D batteries, also known as MN1300, MX1300, PC1300, E95, EN95, 813, and LR20, are required by high-drain devices because they provide a much stronger current. A battery's current is the rate at which a charge is flowing. These household batteries have a higher energy storage and can power electronics for much longer than their smaller counterparts. This is why many of our best-selling camping lanterns, such as the UST 60-day Duro Lantern, are powered by multiple D batteries.

Trusted Brands

BatteryJunction.com is proud to carry the world's most trusted names in batteries, such as Duracell and Energizer. We also offer D batteries from smaller, more industrial-focused brands, like Saft, Vinnic, and Xeno. If that weren't enough, please feel free to browse through each individual brand and their different battery series and selections. Energizer, for example, offers the Energizer Max collection, which is made up of single-use alkaline batteries and offers an assortment of packaging options. There is also the Energizer Industrial collection, which is also alkaline D batteries that are designed exclusively for professional use. These non-rechargeable D batteries have the same stored energy but are packaged more simply to appeal to the industrial user. Finally, Energizer offers Eveready Super Heavy Duty batteries, which have a Carbon Zinc chemistry. While these batteries are called "heavy duty", their real purpose is for low drain electronics. Feel free to browse through our entire selection of Energizer batteries, if you don't see the battery you need here.

Our selection of Duracell D batteries can also be broken down into the following collections: Coppertop, Quantum, and Procell. Each of these single-use batteries is specifically manufactured by Duracell for their extreme reliability; however, the company has developed different options for their varying customers' needs. The Procell collection, for example, was developed to cater to the needs of working professionals. These D batteries are available in smaller contractor packs, which simplifies the package yet allows users to organize the cells in smaller cases than you would typically find from bulk inventory. The Coppertop collection, on the other hand, is the company's well-known retail brand that is perfect for use around the house. Regardless of what sub-series of batteries you choose, you can be confident that all of the Duracell D batteries are made with the same technology and care you've come to know and trust. More Duracell batteries are also available through our site. Why not buy all of the sizes you need from us?

Rechargeable D Batteries

In addition to primary single-use cells, BatteryJunction.com also offers a selection of rechargeable D batteries, available in either NiMH and NiCd chemistry. While these household batteries are reusable and can help minimize your waste, it is important to keep in mind that they provide a lower voltage than single-use alkaline cells. This may or may not have an impact on your electronics' performance, but is something of which you should be aware prior to making any purchase. NiMH batteries may be a better solution for your needs as they typically offer a flatter discharge rate than single-use batteries and they deliver more current. One thing to consider when shopping for D batteries is that NiMH cells have a higher self-discharge rate than alkaline and are more susceptible to warm climates. Our selection of rechargeable D batteries is mostly made up of different packaging options from Tenergy, include both bulk and retail carded packs. Are you looking for different-sized batteries? Feel free to browse through our entire selection of rechargeable batteries, if you are looking for a different size or chemistry than what you see here.
