A D size cell, also known as a D battery, is a large cylindrical battery commonly used in high-drain devices that require extended power. These batteries are much larger than AA or AAA batteries and provide a higher energy capacity, making them suitable for devices that need prolonged or heavy-duty use.
Key Features of a D Size Cell:
- Size: Cylindrical, with dimensions of approximately 61.5 mm in length and 34.2 mm in diameter.
- Voltage: Typically provides 1.5 volts of power, like other standard alkaline batteries.
- High Capacity: Due to its large size, the D cell has a much higher energy capacity compared to smaller batteries (like AA or AAA), making it suitable for energy-intensive devices.
- Chemistry Types: Available in several types, such as alkaline (most common), rechargeable (NiMH or NiCd), and lithium, depending on the application.
- Long-lasting Power: Known for delivering consistent and long-lasting power to devices that require high energy over extended periods.
Common Uses:
- Flashlights: Frequently used in large, powerful flashlights for extended battery life.
- Portable Radios: Often powers radios and boomboxes that demand more energy.
- Toys: Suitable for powering large, motorized toys that require strong, long-lasting batteries.
- Large Remote Controls and Devices: Ideal for larger remote-controlled devices or electronic gadgets that need higher power.
- Emergency Equipment: Used in equipment like lanterns and emergency lighting due to its reliability and long battery life.
D size cells are a reliable source of power for devices that need more energy and longer runtime compared to smaller batteries.
