The capacity (K or C value) of a battery depends on the current with which it''s discharged. The lower the discharge current, i.e. the longer the discharge time, the greater the usable capacity. And vice versa, the greater the discharge current, the less the available capacity. The "K or C" index always indicates the discharge time in hours.
Customer ServiceYang et al. analyzed the capacity fade characteristic of the battery at discharge rate in range of 0.5C to 5C, and proposed a dynamic version Peukert''s law to estimate the battery capacity at different discharge rates [13].

Customer ServiceYes, twice the current discharge means half the time to battery depletion in the ideal case. The capacity (at least to a first order) is the same in both cases. A battery''s capacity is the energy stored, measured in amp hours, ergs, joules, or whatever unit you like.

Customer ServiceSo, let’s start learning about the very important concept of “Battery Capacity”. Battery Capacity is defined as the product of the electric current flowing in or out of the battery in amperes and the time duration expressed in hours. Battery Capacity influences the time for which a device can operate without using power from any other sources.
So twice the power for half the time is the same amount of energy drained from your battery. EDIT: If the question is why would the battery capacity decrease over the expected ideal, then Brian's comment is the answer. The internal battery impedance means more power dissipation at higher currents.
It is also noticed that, the efficiency of the battery sharply increases when the charging current surpasses the discharge current, it is explained using Peukert’s law which states that, “As the rate of discharge of the battery increases, the battery's available capacity decreases”.
In essence, the larger the capacity, the longer the battery can power a device, making it particularly important for applications where long usage times are crucial, such as in electric vehicles, smartphones, and renewable energy systems.
As a result the life of the battery decerases (Mostly for primary cell batteries) Yes, twice the current discharge means half the time to battery depletion in the ideal case. The capacity (at least to a first order) is the same in both cases. A battery's capacity is the energy stored, measured in amp hours, ergs, joules, or whatever unit you like.
At first glance, Eq. (2.10) looks very simple, and for measuring the capacity, all you need is to discharge a battery and record its current versus time. Integrating the resulting data will give the battery capacity. For instance, if the discharging process is constant current, then the capacity is
