What does 100C discharge rate mean?

The C-rate indicates the pace at which the battery delivers energy. The greater the wattage, the faster the discharge rate (C-rate). 1C signifies the battery is completely charged and drained in one hour, 2C equals 30 minutes, and so on, with 10C equaling 6 minutes and 100C equaling 6 seconds.

How does discharge rate affect battery capacity?

The rated battery capacity is affected by the charging/discharging rates. When a battery is depleted fast (due to a high discharge current), the quantity of energy that can be recovered from it is decreased, and the battery capacity is lowered.

What is discharge rate meaning?

The discharge rate is defined as the continuous current in amperes (A) that may be drawn from a battery with a certain capacity (Ah) during a specified time (h). CEGB power station batteries are typically designed at a 10-hour rate.
