The formula is (mAh)/ (Amps*1000) = (hours). For example, if you have a 3000 mAh battery that runs at 0.2 Amps (0.2Amps = 200mA), then the time that the battery will last for is (3000)/ (0.2*1000) = (3000)/ (200)= 15 Hours. If instead of the current you have voltage and watts, then the formula is (mAh*Volts)/ (Watts*1000) = (hours).

milliamp-hours to watt-hours calculation. The energy E (Wh) in watt-hours is equal to the electric charge Q (mAh) in milliamp-hours times the voltage V (V) in volts (V) divided by 1000: E (Wh) = Q (mAh) × V (V) / 1000. So watt-hours is equal to milliamp-hours times volts divided by 1000: watt-hours = milliamp-hours × volts / 1000. or. Wh = mAh × V / 1000

So, for an 1800 mAh battery it could take 10 hrs. at 180 ma charging current (10% of battery capacity). You could speed up the charging time by increasing the charge current to say, 20% of capacity (360 ma) so it would take 5 hrs to charge the battery. You must be careful not to use a charge current that is too high.

Here is a second example of how long to charge batteries but this time for charging 1800 mAh 1.2 volt NiMH aa type rechargeable batteries and with the same current chargers: 100mA battery charger: 12 : 1000 = 0.012. 0.012 x 1800 = 21.6 (hrs)
