It is important to get the voltage when the battery is fully charged. It can be used to verify that if the battery is fully charged, to determine the battery charge and the depth of discharge. Charge Current. The charge current is related to the rated capacity of the battery. It is generally 0.1C~0.4C, which is 1/10 to 4/10 of the rated capacity.
The charging process reduces the current as the battery reaches its full capacity to prevent overcharging. For instance, a lithium-ion battery may charge at a constant current of 1C until it comes to around 70% capacity, after which the charger switches to a regular voltage mode, tapering the current down until the charge is complete.
One crucial consideration is cycle life, which refers to the number of charge/discharge cycles a battery can undergo before its capacity drops significantly. Factors such as depth of discharge (DoD), charge rate, …

Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
