D Rechargeable Battery

A D-size battery or a D battery is quite larger than its AAA and AA counterparts as well as the C dry cells. D-size batteries are available as primary and rechargeable varieties. Like all other batteries, the D-size batteries are dry cells in a cylindrical shape with electrical contacts at both ends. The positive contact has a noticeable metal cap whereas the negative contact is flat. D rechargeable batteries can be used in various devices such as flashlights, transmitters, receivers, paper towel dispensers, megaphones, and other such products that use electric motors.

D Battery Types

A primary D battery is either made of Alkaline, Lithium, Zinc Carbon, or Lithium Iron Disulphide (LiFeS2). Among these, the Zinc-Carbon and LiFeS2 are disposable cells. Alkaline and Lithium batteries are available in rechargeable variants like Lithium-ion or rechargeable Lithium. Other rechargeable varieties of D-size batteries include the Nickel Metal Hydride (NiMH) and Nickel Cadmium (NiCad) batteries with nominal voltages.  

D Battery Dimensions/Specifications

D Battery Dimensions/Specifications

The standard size of a D battery varies between 58.0 and 61.50 mm. The normal diameter is between 33.0 mm and 34.20 mm. A D battery weighs anywhere between 160 and 180 grams. The popular replacement sizes are Type 373, FR20, 13LF, 13A, and 13D, among others. The high-capacity D-size rechargeable cells are rated between 10000 and 12000 mAh. These large, cylindrical-shaped disposable batteries are ideal for applications that need occasional power. These are suitable for both high drain and low drain applications, although certain industrial D batteries are specifically suited for high drain devices. 

Benefits of Primary D-Size Batteries

Benefits of Primary D-Size Batteries

Primary D-Size batteries enjoy several advantages like:

  • They are ideal for situations where recharging is impossible or impractical (for instance, in forest fire services, rescue missions, or military combat).
  • They suit a wide range of applications such as vehicle tire pressure gauges, pacemakers, hearing aids, wrist watches, toys, electric keys, remote light beacons, remote controls, animal tracking, and more.
  • They are ready for immediate use.
  • They come with a longer storage time.
  • Primary batteries offer high specific energy along with sufficient power density and energy.
  • These batteries are cost-effective.
  • They require little or no maintenance.

Rechargeable D batteries are similar to their disposable versions in appearance. However, they are likely to come with specific chargers in a pack, although this might not be the case at times. Although there are universal chargers that work on both C and D-size batteries simultaneously, depending on the brand and other conditions, rechargeable D batteries might need special chargers. Rechargeable D batteries have a lifespan of about 2-3 years, though the longevity depends on several other factors. They come in all forms such as NiMH, NiCad, Lithium-ion, and other Lithium variants. The rechargeable D-size batteries tend to be pricier than their primary counterparts.

However, it doesn’t mean the rechargeable batteries don’t have many advantages over the primary batteries. Some benefits of using Rechargeable D batteries include:

  • Suitable for a wide range of applications
  • They are less wasteful and polluting
  • Can be recharged and used multiple times 
  • Despite the initial high cost, the overall cost is low in the long run
  • Lesser chances of running out of usable batteries 
  • Environmentally friendly
  • Comes with a higher capacity that lasts 2-4 times longer than other dry cells
  • Better performance means they are ideal for high drain applications
  • Long battery life as they can be recharged up to 500-1000 life cycles
