Capacity rating Factor Kt in Battery sizing - IEEE 485
Capacity rating Factor Kt in Battery sizing - IEEE 485
(OP)
As in IEEE-485,
Kt factor is the ratio of rated Ampere-hour capacity to the Amperes that can be supplied by that cell for T minutes at 25 degree celcius to a given end of discharge voltage.
How do we come to know this rated Ampere-hour capacity of the battery before calculating? (as we are doing this to arrive at the same).

Alternatively you can measure it. Measure it at the expected draw for your application.

But, the question you're asking seems backwards. You determine what capacity you need from whatever is using the battery, i.e., if it's 12V at 1A, or 10A, and you account for the intensity of the draw on the capacity of the battery, and then you select a battery that meets the requirement.
