Lead-acid batteries have a low impedance, therefore the ability to deliver high currents. Hence the large, short circuit current specified on battery datasheets, e.g., 2,500A for 12V 80 Ah battery. …
Description. This lead acid battery charger circuit is designed in response to a request from Mr vdas .C. His requirement was a circuit to charge two 12V/7AH lead acid batteries in series.Anyway he did not mentioned the no of cells per each 12V battery. The no of cells/battery is also an important parameter and here I
I have a lead Acid battery which is 12 volt 72AH. The load I applied to it is a fan of 12volt 9 amp. It only runs about an hour and slows down. As per my battery capacity it should run almost 7 to 8 hours. I have checked my …
