Voltageĭespite the large size of a D Battery when compared to AA and AAA batteries, the typical voltage of a D Battery is still 1.5V. The data sheet of the battery or manufacturer’s description will specify the negative terminal contact i.e., flat or recessed. Irrespective of the type of the negative terminal, its diameter must be at least 18 mm. In addition to the flat negative terminal, as we find in AA and AAA batteries, some D Batteries also come with recessed negative terminals. The height of the positive terminal must be at least 1.5 mm while the diameter of the positive terminal must be less than or equal to 9.5 mm. We know that the positive terminal in most cylindrical batteries has a protrusion. Coming to the diameter of the D Battery Cylinder must be a minimum of 32.2 mm and a maximum of 34.2 mm.Īpart from these two dimensions, we also have dimensions of the positive and negative terminals. If you take the height or length of a D Battery, the minimum height is 59.5 mm while the maximum height is 61.5 mm. The first and most important specification of a D Battery is its physical size. But what is the actual size of a D battery? What are the other important specifications of a typical D Cell? Let us explore more about these aspects of a D Cell Battery. In the previous section, we mentioned that the D Battery is a bigger version of the AA battery. We will give more details about the D Cell Battery in the next section.
Even the U.S Military used these batteries in radio transceivers during World War II. Even after the introduction of more minor AA and AAA batteries, D Cells were very popular for a long time, especially for flashlights. While The American Ever Ready Company introduced AA and AAA batteries in 19 respectively, the National Carbon Company introduced the D Battery (or D Cell) much earlier in 1898. Hence, we often call the D Battery the D Cell.
A D Battery is a slightly longer and wider version of an AA or AAA battery.Īnother similarity between a D Battery and AA or AAA batteries is they all have only one cell, which is the main electrochemical unit. This is because we used them extensively to power those long flashlights that took two (or sometimes three) of these batteries.īut what exactly is a D Battery? A D Battery is a type of cylindrical battery, where the ‘D’ indicates the physical size of the battery similar to AA or AAA (if you remember, AA and AAA also represent the size of the batteries). If you fall into the millennial, Gen-X, or boomer demographic, then chances are you are familiar with D Batteries as flashlight batteries. Comparison Of Types Of D Cell Batteries.We deal with major brands in the niche of flashlights like Pelican, Browning, Maglite, and Streamlight. We offer different types of D-Cell Flashlights like 2D Cell Flashlights, Aluminum LED Flashlights, 3D Cell Flashlights, Rechargeable LED Flashlights, 6D Cell Flashlights, and 5D Cell Flashlights. We are one of the most sought after online retailers for flashlights and accessories throughout the world, especially in USA. This means a longer battery life when you need it most! Energy Conservation for Longer Battery Lifeĭ-cell Flashlights regulate brightness and power usage with an emphasis on ensuring you manage some energy savings. This means the maximum ease-of-use during emergencies.Ĥ. Offering utmost ease of operation, D-cell Flashlights can be switched on/off with a single button movement. This includes planned activities or unexpected situations, both pleasant and unpleasant!ĭ Cell Flashlights have a powerful light throw, which can cover distances over a few miles! The impressive Spot-to-Flood adjustable LED Beam makes a D-battery Flashlight comparatively better than A and C type of flashlights. These multi-purpose D Cell Flashlights are very easy to handle in all types of situations. Here, Knife Country USA's team tries to explain the salient features of D Cell Flashlights:ĭ Cell Flashlights are ideal for use at home and for outdoorsy activities. This increasing popularity is due to many reasons. The D-cell Battery can be rechargeable or non-rechargeable but all the variations have a terminal voltage and capacity, defined as per the cell’s chemistry. This includes many types of safety systems, Geiger counters, and megaphones.
D Cell batteries are used in larger flashlights, radio receivers, and transmitters apart from boom-boxes and heavy-duty products with electric motors. A D Cell Flashlight is ideal for high-current applications since the D-cell battery has impressive, high-output attributes. D Cell Flashlights are exclusive, high-performance flashlights that use the D-cell battery.
