Following equation or formula is used for Battery Charging Time calculator. Based on the above calculation, suitable battery charge time can be understood. I have a solar battery charger which puts out 15 watts an hour @ 15 volts. at time zero, when the switch is first closed, the capacitor gradually charges up through the resistor until the voltage across it reaches the supply voltage of the battery. The formula for calculating the charging current is: I = Q * k, where Q is the battery capacity, and k is a certain ratio of the nominal (its ideal value is within 0.04… 0.06, and the optimal value is 0.1). Recommended when eliminating the sulfatation of electrodes caused by prolonged use of the battery with less than 70% charge. How to Calculate the Charging Time and Charging Current for Battery Charging? Calculating the charge time of a … Can i get a reference material for the above calculations??? what can wrong happen, if I will charge 12V 9Ah lead-acid battery by 7Ah battery charger? Required fields are marked *, All about Electrical & Electronics Engineering & Technology. ?can 14ah charging current is higher to charge the battery??? Sir,,,,i use 200ah tall tubular battery of amaron company… battery rating is 200ah….can i supply charging current 14ah to charge the battery??? If the PV cells are used as a current source for the batteries, then 2 arrays will supply a total of 4 amps peak, and an efficiency of 50% will give an effective charge rate of $$C = 2\times 2 \times 0.5 =2 Ahr/hr$$ rather than 2.9. What Happens if a Battery is Connected to the AC Supply? First of all, we will calculate charging current for 120 Ah battery. So what will be my batteries charging time.. How i calculate my batteries charging time?? If loss is above 40%, you need to attempt to find the reason by changing the charger or replacing the battery. of it rating [20Ah].
Therefore, [20Ah x 10]/100 = 2A.
Ideally, the charging current for this battery would be 2A.
but due to losses, we can take 2-3A for charging propose.
Now charging Time = Battery rating / charging current
