The typical capacity of an alkaline D battery ranges from 12,000 to 18,000 mAh (milliampere-hours).
Here's a more detailed breakdown:
-
Alkaline D Batteries: These are the most common type and offer a capacity of 12,000-18,000 mAh, which translates to roughly 18-27 Wh (watt-hours) of energy. They have a nominal voltage of 1.5V.
-
Rechargeable D Batteries: Rechargeable D batteries, such as NiMH (Nickel-Metal Hydride), also exist, though they're considered a specialized type. Their capacities can vary, but typically fall within a similar range as alkaline batteries, although performance characteristics might differ under various loads.
It's important to note that the actual capacity can vary depending on the brand, the discharge rate (how quickly the battery is used), and the operating temperature.
