The D-cell battery is the best option for those who want a more compact battery. It was invented in 1898 by the National Carbon Company. For years, D cells were known as flashlight batteries, and the US military has known this battery as BA-30 since before WWII. D-size battery packs are much larger than AAA and AA batteries. As with the C dry cells, these have a greater diameter. There are both primary and rechargeable versions of these cells available.
High-drain applications like flashlights, automatic odorizers and paper towel dispensers use D batteries. D batteries are also used in radio receivers and other devices that need to run for long. The positive end of a D cell features a nub or bump, and the opposing end is cylindrical.
It has a wide range of terminal voltage and capacity depending on the cell chemistry. Learn more about this battery by reading the entire article. From the most basic to the most in-depth information about D-Cell batteries, features and specifications, we’ve compiled it all here.
What Is a D Cell Battery?
Typically, a D battery is referred to as a “dry cell.” These interchangeable types are used in a wide range of electrical and residential equipment. So you might be thinking, ‘are all D batteries the same?‘ Differentiating between ‘dry cell’ batteries and the more specialized ‘wet cell’ batteries is done by using the phrase ‘dry cell.’
The shape of a D-size battery is barrel-shaped and squat. The positive contact point or terminal has a unique metal cap form in each battery. The International Electrotechnical Commission (IEC) designated these as R20s, also known as flashlight batteries, MN1300, MX1300, LR20, R20, 13A, 13D, Type 373, BA-30, and so on.

D-cell Battery Types
As previously stated, D batteries, like many other sizes, are also available in non-rechargeable and ecologically friendly rechargeable forms, as are many different sizes. A rechargeable D battery can be recharged and utilized several times instead of having to replace a depleted battery. Following are the details:
Non-Rechargeable D-cell Batteries
It is a primary battery, and it is built up of electrochemical cells, and the electrochemical process that occurs in these cells cannot be stopped. Once a non-rechargeable D battery has been emptied, it is impossible to replenish it. Standard D cell batteries have a lower capacity than rechargeable D cell batteries, which are typically more powerful.
Lithium-ion, lithium-polymer, zinc-carbon, and lithium-iron disulphide are all possible materials for primary D cell batteries (LiFeS2). Zinc Carbon and LiFeS2 are the only two chemistries among them that are designed to be completely disposable cells.
Zinc-carbon D-cell Batteries
Zinc-Carbon D-cells have a capacity of 6000-8000 mAh and a voltage of 1.5 volts. The most popular Panasonic D-cell battery with a nominal voltage of 1.5V can power most devices.
Zinc-carbon D-cells have a 3-5 year shelf life and are affordable and reliable. Their shelf life can be reduced to 1-2 years if not stored properly. Also, due to their chemistry, they may leak over time.
Alkaline D-cells Batteries
Alkaline D-cells are slightly more expensive than zinc-carbon batteries but have a substantially larger capacity (12-18 Ah) and a 5-10 years shelf life. For everyday gadgets like flashlights, alarm clocks, remotes, and more, Energizer MAX D long-lasting batteries are the best option for you.
Some battery manufacturers claim that their D-cells have a capacity of 20+ Ah, although this is only true when the batteries are being drained at low currents (15-30 mAh). Most D-cell batteries are alkaline, and alkaline batteries have significant advantages over zinc-carbon batteries.
Lithium-thionyl Chloride (Li-socl2) D-cell Batteries
Li-SOCL2 batteries are specialized D-cell batteries. These 3.6V batteries are not compatible with 1.5V D-cell batteries. They also have a huge 18-19 Ah capacity and a 20+ year shelf life, such as,
D Cells are fresh and very reliable, ensuring long-lasting power.
But Li-SOCl2 D-cell batteries can’t deliver higher currents. Lithium-Thionyl Chloride (Li-SOCl2) D-cell batteries have a maximum continuous discharge current of 50-150 mAh. As a result, Li-SOCl2 D-cell batteries are widely utilized in electronics.
Rechargeable D Batteries
The most common rechargeable batteries are nickel-cadmium (NiCd) and nickel-metal hydride (NiMH) (NiMH). Both use nickel-metal hydroxide as an “electrolyte” (electricity-conducting substance). NiCd rechargeable D cells are marked as KR20, while NiMH rechargeable D cells are classified as HR20.
Rechargeable batteries have improved in recent years, becoming more dependable, longer-lasting, and less expensive. They are safe for the environment and maybe recharged hundreds of times. Despite this, many individuals prefer to use disposable ones because they have a longer initial shelf life. When purchasing rechargeable batteries, you will also need to acquire a rechargeable battery charger to go along with them.
Nickel-Cadmium (NiCd) D-cell Batteries
These batteries contain cadmium, a heavy metal that is a major contaminant and rarely used. NiCd batteries have a memory effect, high self-discharge rate, a nominal voltage of 1.2 volts, and 2-6 Ah capacity. PKCell NiCd D Size 5000mAh flat top rechargeable batteries with tabs have a 500-1000 rechargeability range.
When properly maintained and charged with sophisticated chargers that monitor the batteries’ status, NiCd batteries can withstand several hundred charging and discharging cycles. Then again, a few NiCd D-cell batteries may deliver 50+ Amps.
Nickel Metal Hydride (NiMH) D-cell Batteries
NiMH D-cell batteries have a comparable output voltage of 1.2 volts as NiCd batteries. They have a larger capacity (8-12 Ah), no heavy metals like cadmium or mercury, a lower self-discharge rate, and can last up to 1000-1200 charge/discharge cycles.
High-drain NiMH batteries have a lower capacity, while low-drain NiMH batteries have a larger capacity. For example,
EBL Ni-MH D Cells Rechargeable Battery has no memory effect, can be recharged and used at any time, and contains a high-quality cell. The typical NiMH D-cell capacity is 10 Ah, and modern Ni-MH batteries surpass NiCd batteries in practically every manner, making them the favored battery chemistry for rechargeable D-cells.
