D Batteries are a standard size of dry cell battery that are used for higher drain power applications. They are often referred to as 'Flashlight Batteries', due to their use in large torches which require long lasting power and performance. D Cell batteries are still commonly used in many larger appliances, such as portable radios and electronic toys. To learn more about D batteries and for help choosing the best battery for your purposes, please see our D batteries guide.
What are rechargeable D batteries?
Rechargeable D batteries are also available, with the advantage of being reusable after being placed in an appropriate charger. This is not just economically advantageous for the user, but also a more environmentally conscious choice for power application.
