Long time ago these batteries were known as flashlight batteries for understandable reasons – they were commonly used to power flashlights. Nowadays this role is fulfilled by smaller and lighter batteries, which is driving popularity of D cells down.
Are D batteries the same as AA?
The D cell will be able to power the light bulb for much longer than the AA cell, because of the higher energy storage. The output voltages are the same initially, and the bulb resistance is the same, so by V=IR, the currents will be the same.
AAA, AA, C, and D batteries are all 1.5 Volts. Regular, heavy duty, and alkaline, all are 1.5 volts. SInce they don’t make rechargeable D batteries, this allows you to use rechargeable AA batteries in devices that take D batteries. It is still rechargeable, but will not last as long as a regular D battery.
What size is D battery?
The standard size of D battery is: Diameter: 33.2 mm/1.3 inches. Length: 61.5 mm/2.42 inches.
I just learned that D4 just means there are 4 batteries to the package —– they are regular D batteries.
What is a 4D battery?
One group size down is 4D batteries. 4D batteries typically have dimensions around 21″x9″x10″ (LxWxH) and weigh between 100-150 pounds. Since they are slightly smaller, they tend to have less capacity and fewer cold-cranking amps. On average, 4D batteries have between 150-220 amp-hours and 900-1,300 cold-cranking amps.
Can I use C batteries instead of D batteries?
If you’ve only got C batteries for your D-battery device, you can sometimes make up the difference with a few quarters. It’s not a great permanent solution, but it will do in a pinch. For each battery to be adapted, you’ll usually only need 3 or 4 quarters (or less than $1!).
Larger objects need more power. That meant larger, more powerful batteries had to be developed. As technology led to smaller and smaller versions of things, smaller, less powerful batteries were needed. However, battery makers soon realized that some common standards would be needed.
Does D battery last longer than AA?
The D size battery will deliver more current than the C, AA, and AAA size battery. So even if a AA battery and a AAA battery are both rated as having a voltage of 1.5, the AA battery will deliver more current than the AAA battery.
Why do D batteries exist?
A D battery (D cell or IEC R20) is the size of a dry cell. D cells are typically used in high current drain applications, such as in large flashlights, radio receivers, and transmitters, and other devices that require an extended running time. A D cell may be either rechargeable or non-rechargeable.
What is the advantage of D batteries?
That’s where battery size comes in. The D size battery will deliver more current than the C, AA, and AAA size battery. So even if a AA battery and a AAA battery are both rated as having a voltage of 1.5, the AA battery will deliver more current than the AAA battery.

Which is better Energizer or Duracell D batteries?
When comparing rechargeable AA batteries, Gizmodo found that Duracell lasted longer (5 to 6.5 hours) than Energizer batteries (2 to 3.5 hours). Higher is usually better but the battery life findings were contrary to the listed mAh ratings of the batteries.
How do you install D battery?
On AA, AAA, C, and D batteries, the positive end should be slightly raised. The negative end of the battery should be flat, and it may or may not be marked with a minus, or -, symbol.
