How to Calculate the time of Charging and Discharging of battery?
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.
What is the Recommended Charging Current for a New Lead Acid Battery?
For instance, if you have a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah, and the charging current should not exceed 11.25 Amps. It is crucial to avoid exceeding the recommended charging current as this can lead to thermal runaway and battery expiration.
