What is the Battery C‐Rate?
A battery’s C rating is the rate at which a battery can be fully charged or discharged. For example, charging at a C-rate of 1C means that the battery is charged from 0 – 100% or discharged from 100 – 0% in one hour.
A C-rate higher than 1C means a faster charge or discharge, for example, a 2C rate is twice as fast (30 minutes to full charge or discharge). Likewise, a lower C-rate means a slower charge or discharge, as an example, a C-rate of 0.25 would mean a 4-hour charge or discharge.
The formula is:
T = Time
Cr = C-Rate
T = 1 / Cr (to view in hours), or T = 60 min / Cr (to view in minutes). For example:
C-Rate. Time
2C. 30 minutes
1C. 1 hour
0.5C. 2 hours
0.25C. 4 hours
