the difference between “Rated Capacity” and “Typical Capacity” of a battery

Question

Note 10+ battery says the rated capacity is 4170 mAh while typical capacity is the advertised 4300 mAh. Why the two numbers?

In: Technology

Answer 1

“rated capacity” is the capacity of a battery drawn at a certain discharge rate. e.g. for my AGM batteries the “rated capacity” is at a 5 amp draw over 20+ hours to get 105 amphours.

If you draw slower than that you will get slightly more than 105Ah total and if you draw faster you will get less.

“Typical capacity” is the expected discharge rate of the application. For instance, in an EV car the “typical” discharge rate might be 20kW for batteries designed for (more or less than that rate).

Answer 2

Typical capacity is the average of all the phones’, of this model, battery capacity but the rated capacity is your own phone’s battery capacity
