Does a battery''s charging current depend on its capacity?
For example: "The battery was charged at 0.5C ." It''s not temperature in Celsius, and it''s not capacitance in Farads. C-rate is current in Amperes that''s numerically equal to the capacity of the battery in Ampere-hours. Charging a 3Ah battery at 0.5C means that the charging current is 1.5A . Max charging current is usually expressed as C-rate.

8.2: Capacitors and Capacitance
Since capacitance is the charge per unit voltage, one farad is one coulomb per one volt, or [1, F = frac{1, C}{1, V}.] By definition, a 1.0-F capacitor is able to store 1.0 C of charge (a very large amount of charge) when the potential difference between its plates is only 1.0 V. One farad is therefore a very large capacitance.
