C vs D battery differences and comparison
Batteries are generally defined as storage device which stores energy and discharges it by converting chemical energy into electrical energy.
Typical batteries comprise electrochemical reactions into cells due to chemical reactions; ions are formed and collected at respective electrodes inside the batteries. Batteries are used in multiple things around our house and offices, like remote controls, torches, flashlights, etc.
These batteries are classified into primary and secondary batteries; C vs D battery are divided into rechargeable and non-rechargeable types, depending on the material of the battery, most of which refer to nickel batteries, including C-type nickel-metal hydride batteries and C-type nickel-cadmium batteries.
What is a C battery
Let us begin by discussing C batteries; C batteries are a widely used type of dry cell initially designed to function at very low capacity , making these batteries reliable for portable purposes. The standard dry batteries include AA and AAA, the height of the c battery is 49.5±0.5mm, and the diameter is 25.3±0.2mm.
These batteries are used in torches, cameras, radio, musical instruments, and others; hence, they are called primary batteries, meaning they are not rechargeable once used, but some are rechargeable. C batteries are called R14s or c LR14 batteries, appointed by International Electrochemical Commission (IEC) as the permanent electrical standard bodies.
Volt capacity of C batteries includes 1.5 Volts which is standardly used daily in household equipment.
What is D battery
The next one is the secondary or primary type of D batteries. D cell is also called IEC R20. It is the standard size for all dry cell batteries; The height of the D battery is 59.0±0.5mm, and the diameter is 32.3±0.2mm.
D batteries are mainly used in transmitters, radio receivers and military, special DC power supply. A typical D-type battery is 1.5 volts, the same as a C-type battery.
Is there a lithium C vs D battery
Yes, rechargeable lithium C vs D battery are available in the market. Commonly used are 3.7v 3200mAh-3300mAh. Compared with nickel-metal hydride batteries, lithium batteries as high voltage battery, have higher discharge power, fast reflow speed, and fast charging speed.
It can meet a wider range of application scenarios, and even reduce the voltage to 1.5v to replace traditional nickel-metal hydride batteries.
What is the difference between C vs D battery
Let’s discuss some of the significant differences between C vs D battery:
- Battery size
The alphabet represents the size of the battery. The further away from the alphabet larger the size of the battery; They are different in diameter and height. Therefore, AAA batteries are more minor, and D batteries are the largest. - Capacity
The larger size is mainly recommended when looking for more capacity in batteries; however, In the case of the same material. In the case of the same material, D batteries are more bigger than C batteries which last more and store more energy resulting in more durability. In terms of mAh, C batteries have a capacity of upto 8000 mAh while the capacity of D batteries is 17000 mAh. - Application
C batteries are primarily preferred in devices that are typically smaller in size and do not need more energy to operate, like flashlights, toys etc. and D batteries are used in larger electronic devices like alarm systems and large flashlights, and these batteries last longer than C batteries. C battery is suitable for lighting circuit, D battery is suitable for power circuit, the overload capacity is stronger than C battery, and it is more commonly used in industry.
What can you use C batteries for
Many small electronic gadgets are used C batteries as their source of energy motorbike headlamps works with the help of C battery, small flashlights, musical instruments, remote controls, small electronic fans, hearing aids, various cameras, communications devices like two-way radios, and much more.
What are D-sized batteries used for
D-sized batteries are typically used in high current applications due to their larger capacity and size for storing energy. They are used as large flashlight battery, radio receivers, transmitters, and many other devices that need more power. These batteries can be chargeable and not chargeable as well.
Pros and cons of C vs D battery
Here we have enlisted some of the advantages and disadvantages of C vs D battery:
Pros
- ● C batteries lighter in weight, more portable, easy to carry
- ● C batteries charging time is shorter
- ● D batteries’ sizes are larger, which gives out more energy.
- ● D battery lasting is more.
Cons
- ● C batteries are smaller in size, so less energy is supplied
- ● Running time for small C batteries is less as compared to d battery
- ● D batteries are not as light as C batteries
| Battery type | C battery | D battery |
|---|---|---|
| Weight | Lighter | Heavier |
| Capacity | Smaller | Bigger |
| Height | 49.5±0.5mm | 59.5±0.5mm |
| Diameter | 25.3±0.2mm | 32.3±0.2mm |
| Power | Lower | Stronger |
Do D batteries last longer than C batteries
Yes, the D battery can last much longer tha C type battery because D type battery is in a bigger capacity than C batteries. Therefore, these batteries can supply more energy, so if you require more energy and rely on some tiny batteries, it won’t work out for you.
On another side, the battery life and endurance also depend on the material of the battery. Now the c vs d batteries using lithium materials will last longer and have better performance than the traditional ones. Even under the same material, D batteries are still more durable than C batteries.
Can C batteries replace D batteries
Similarly, C batteries can be used in place of D batteries, but you need to ensure that C and D batteries’ voltage capacity is typically the same; both are 1.5 volts and make sure it fits into the battery slot.
For instance, in a flashlight, the voltage determines how powerful the light can be. The current will describes how long the flashlight will glow, so when the flashlight starts its function, the large battery will result in more brightness means high amps produce more bright light. That is not the case. Replacing C with D makes no change in the brightness of the flashlight.
when we replace the battery, just put 2 double A batteries into the converter and start operating like the D-type batteries. There are typically the best tips for emergencies, and you can also use this technique on many electronic devices.
Are C batteries more powerful than 18650
18650 is a battery with 18 mm diameter and 65 m in length typically lithium-ion battery larger than rechargeable aa battery on other hand C battery are 50mm in length and 26.2 m in diameter making these batteries with 1.5 voltage/3000 mAh capacity whereas 18650 has voltage capacity of 3.6 volt/2300-3600 mAh making 18650 more powerful than c batteries
Conclusion
C and D batteries typically vary in energy, consumption rate, sizes, and duration, and many different factors are involved in both; However, c vs d battery each has the most suitable application scenarios, so the two cannot completely replace the existence of the other.
