0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity. For example, a battery rated at 1000mAh provides 1000mA for one hour if discharged at 1C rate. The same battery discharged at 0.5C provides 500mA for two hours.
It is expressed as a multiple of the battery''s capacity. For example, a discharge at 1C means that the battery''s entire capacity is discharged in 1 hour, while a discharge at 0.5C means it takes 2 hours to fully discharge the battery. Similarly, a charge at 2C means the battery is charged to its full capacity in 0.5 hours.
