Answer: Look along the "1.75 V" line, and you see that the battery could supply 23.5 A for 10 mins or 17.4 A for 15 mins. A graph from the manufacturer would be helpful (since the discharge current vs. time plot is a curve and not a straight line). However using a linear interpolation between those two given values (23.5 A for 10 mins, and 17.4 ...

The battery C rating is the measurement of current at which a battery is charged and discharged. It represents the discharge rate relative to the battery''s maximum capacity. For example, a battery with a 1C rating can provide a current equal to its capacity for one hour. The C rating helps determine the maximum safe continuous discharge rate ...
Charging Voltage: This is the voltage applied to charge the battery, typically 4.2V per cell for most lithium-ion batteries. The Voltage-Charge Relationship: Why It Matters. The relationship between voltage and charge is at the heart of lithium-ion battery operation. As the battery discharges, its voltage gradually decreases. This voltage can ...
When reading the battery specifications, you may have noticed that the charge and discharge current of the LiFePO4 battery cell is indicated by "C". What is C rating? A C rating is a rating of how quickly a battery can release energy. This rating is combined with the capacity of the battery to determine the

Another important factor that affects the voltage of your battery is the discharge rate. When you use your battery, it discharges, and the voltage drops. The rate at which the voltage drops depends on how much current is being drawn from the battery. To give you a better understanding, let''s take a look at the following table that shows how the voltage of a 12 …

The battery capacity also greatly depends on the discharge current. For example, compare a 20 hour and a 1 hour rate: For 20 hours, 0.05C (A) x 20 (h) = 1C (Ah) For 1 hour, 0.6C (A) x 1 (h) = 0.6C (Ah) This means that the capacity for the one hour rate is 60% less of the 20 hour rate. Evidently, increasing discharge current causes a decrease in ...
