Battery Charging terms explanation
C20 is the usual measure, when the battery is discharged over 20 hours. Other common rates are C5 (5 hours) and C100 (100 hours). So if you''re a manufacturer giving recommended charging values, you have to be specific about which rate you are talking about. 0.2C5 is 0.2 x the C5 rate. If the battery C5 capacity is 100Ah, 0.2C5 is 20 amps.
