Charging time and charger output
It would appear that battery charging times are a function of the square root of the ratio of the charger output. In other words doubling the output does not cut charging time in half. It only cuts the time by multiplying by 0.707 or the inverse of the square root of two. If you want to cut charging time in half you have to increase your charger output by four times. I'm sure that I am not the first to notice this. Is my arithmetic correct? Thanks. Steve S.
