The internal resistance of all Viada batteries is the smaller the better, the smaller the internal resistance, the

stronger the large current discharge capacity, the more adequate the release of electric energy.

Any power supply has more or less a certain internal resistance, in order to improve the load capacity, we hope

that the internal resistance of the power supply is as small as possible.

In the figure above, the resistance r is the internal resistance of the car battery, and RL is the load, which is

in series with the internal resistance r, and the current flowing through r is equal to the load current. Assuming

that the size of r is unchanged, the greater the load current, the greater the current flowing through the interna

l resistance r, the higher the voltage at both ends of r, so that the voltage added to both ends of the load RL is r

educed, if the pressure drop on the internal resistance is too large, and even lead to RL can not obtain the rate

d operating voltage and can not work normally, so we hope that the internal resistance of the battery as small a

s possible, so that when driving heavy load, There is no significant pressure drop on the internal resistance.

The internal resistance of the battery will increase with the growth of the use of time, especially the fast scrappe

d battery, the internal resistance increases significantly, although the battery voltage is higher after full charge, but because the inter

nal resistance becomes larger, a large current load is connected, the internal resistance will produce a larger vo

ltage drop, so that the voltage at both ends of the load is reduced.
