Disadvantages of the load test method:

(1) Only available for large capacitance battery or storage battery. The small capacitance battery can not load 40-80A large current in 2-3 seconds. (2) When the large current going through the battery, there comes out a polarization phenomenon from the internal electrode, which can cause polarization internal resistance. As a result, it has to be tested in a short time. Otherwise, there will be a large error in the internal resistance value. (3) The internal electrode will be damage generally when the large current goes through the battery.
