An alkaline D-cell battery usually has a capacity of about 8 amp hours (Ah). In comparison, high-capacity nickel-cadmium (Ni-Cad) batteries offer around 4 Ah, while standard Ni-Cads provide about 2 Ah. This means alkaline D-cells have the highest capacity among these battery types.
The amp hour rating is crucial for users selecting batteries for specific applications. A higher amp hour rating usually means longer run time for a device. However, it’s important to consider that alkaline batteries are not rechargeable. This limits their use in devices that require frequent battery changes or longer operation times.
Understanding the capacity of alkaline D-cell batteries is essential for optimal use. This knowledge helps consumers choose the right battery for their needs and avoid unnecessary waste. In the next section, we will explore alternatives to alkaline D-cell batteries, focusing on rechargeable options and their respective capacities. These alternatives may provide a sustainable solution for high-drain applications.
