The charging current (in A units) can be written as C/t where t is a time. For example, for a battery with C = 40 Ah, a current C/10 is equal to 4 A. The charging current is a compromise between charging time (favoring high currents), the prevention of damage due to overheating or outgassing (favoring low currents), and cost of the charger ...
