Anyone knows what is the approx. internal resistance of a lead battery, say, 12V, 20Ah.
Thanks
Thanks
I just think that the higher the capacity, the bigger the electrode plates, so the internal resistance should be smaller.I'm not 100% sure on this, but I don't think that the battery's capacity matters.
That's mainly true for the same type of battery construction but the total ionic resistance is a combination of factors like electrolyte conductivity, separator ionic resistance, ion mobility and electrode surface area.I just think that the higher the capacity, the bigger the electrode plates, so the internal resistance should be smaller.
