Difference Between C and D Batteries
When it comes to powering your everyday devices, choosing the right battery size makes a huge difference. Two of the most common household battery types are C batteries and D batteries. While they may look similar at first glance, there are key differences in size, capacity, and usage that determine which one is the right fit for your device.
Batteries Store Calgary carry a wide variety of C and D batteries to keep everything from toys to flashlights running smoothly. Let’s break down the difference between C and D batteries so you can make an informed choice.
What Are C Batteries?
C batteries are medium-sized cylindrical batteries commonly used in devices that require moderate power over a long period.
Size: Approximately 50 mm in height and 26 mm in diameter.
Capacity: Around 3,800 to 8,000 mAh (depending on the brand and chemistry).
Common Uses: Toys, portable radios, small flashlights, musical instruments, and medium-drain devices.
C batteries are a perfect balance between compact size and decent energy storage, making them versatile for many household items.
What Are D Batteries?
D batteries are larger cylindrical batteries designed for high-drain devices that need more power for longer durations.
Size: Approximately 61.5 mm in height and 34 mm in diameter.
Capacity: Around 12,000 to 18,000 mAh (depending on brand and chemistry).
Common Uses: Large flashlights, radio transmitters, camping equipment, boomboxes, and high-powered toys.
Because of their bigger size and higher capacity, D batteries are the go-to choice for devices that demand strong, long-lasting power.
Key Differences Between C and D Batteries
While both are cylindrical and look alike, here’s how they compare:
| Feature | C Batteries | D Batteries |
| Size | Smaller (50mm x 26mm) | Larger (61.5 mm × 34 mm) |
| Capacity | 3,800–8,000 mAh | 12,000–18,000 mAh |
| Power Output | Suitable for medium-drain | Suitable for high-drain |
| Typical Uses | Toys, radios, small gadgets | Flashlights, camping gear, audio systems |
| Weight | Lighter, easier to carry | Heavier, longer-lasting power |
Which One Should You Choose?
If you’re powering a portable radio, toy, or smaller flashlight, C batteries are ideal.
If you need batteries for emergency flashlights, camping equipment, or heavy-duty devices, D batteries are the better option.
Choosing the right battery ensures longer runtime, better performance, and prevents unnecessary replacements.
Are there rechargeable D and C batteries?
Yes — both C batteries and D batteries are available in rechargeable versions.
Chemistry: Most rechargeable C and D batteries are NiMH (Nickel-Metal Hydride) or Lithium-ion.
Voltage: Usually 1.2V (slightly lower than standard alkaline 1.5V, but works fine in most devices).
Capacity:
- Rechargeable C batteries: typically 2,200–6,000 mAh
- Rechargeable D batteries: typically 3,000–10,000 mAh
Lifespan: Can be recharged hundreds of times, making them eco-friendly and cost-effective in the long run.
When to Use Rechargeable C and D Batteries
Perfect for high-drain devices like flashlights, camping gear, radios, and toys that consume a lot of power.
Best if you frequently replace batteries in your devices—rechargeable save money and reduce waste.
Things to Keep in Mind
You’ll need a compatible charger designed for C and D battery sizes.
Capacity may be slightly lower compared to disposable alkaline D or C batteries, but the reusability outweighs the difference.
