D batteries are typically used for devices that consume high amounts of energy and require long-term power. Their large size and high capacity enable them to meet long-term, high-power demands, making them suitable for applications requiring high power stability.

This type of battery is commonly found in devices requiring stable current output, such as large flashlights and portable speakers. These devices require continuous power during operation, and the large capacity of D batteries reduces replacement frequency and improves user convenience.

D batteries are also suitable for some outdoor or emergency equipment. Their storage durability and low self-discharge make them excellent for applications requiring long-term backup power, such as emergency lighting or outdoor exploration equipment.

D batteries are also used in some children's toys and power tools. These devices typically require high power and are used erratically. The high capacity and cost-effectiveness of D batteries offer a good balance between performance and cost.
