  • Specification Datasheet:

Rated Capacity:

This is the total amount of charge a battery can store as determined under controlled conditions, usually specified by the manufacturer. It's often measured under ideal conditions with a specific discharge rate, temperature, and cutoff voltage. The rated capacity is usually determined using standard testing procedures that might not perfectly replicate everyday usage but provide a consistent basis for comparing different batteries.

Typical Capacity:

This term is less formal and is often used to describe the battery capacity that a user can expect under normal usage conditions, which may differ from the controlled conditions used to determine the rated capacity. Typical capacity can take into account more realistic factors such as variable discharge rates, temperature variations, and aging of the battery. It's an estimate of what users might experience more regularly, thus providing a more practical perspective on the battery's performance.
