Battery C Rating Chart
The C-rating indicates the maximum safe continuous discharge current that can be drawn from the battery, with higher C-ratings allowing for faster discharge but reduced overall capacity.

To work out the discharge time (the “C-rate”) from the Nominal Capacity and the Discharge current, divide the Nominal Capacity by the Discharge Current. This will give you the C-rate.

Since a batt ery may be rated, i.e. its performance specified, for different discharge times, its rated capacity should normally indicate the current used. The discharge current may alternatively be

C- and E- rates – In describing batteries, discharge current is often expressed as a C-rate in order to normalize against battery capacity, which is often very different between batteries. A C-rate is a

Batteries are seldom fully discharged, and manufacturers often use the 80 percent depth-of-discharge (DoD) formula to rate a battery. This means that only 80 percent of the available energy
