The battery capacity decreases with the increase of discharge current.This is because the current distribution is not uniform on the plate, the electrochemical reaction current priority distribution in near the main solution to * * * on the surface, thus leading to the electrode surface of lead sulfate and orifice, electrolyte diffusion difficulties, inadequate supply of porous electrode internal needs, when large current discharge, the active material along the thickness direction effect depth is limited, the larger the current depth of the role of the shallow, the lower the degree of active substances used, and the smaller the capacity of the battery have given.Due to the existence of polarization and internal resistance, the increase of voltage drop loss at high current density makes the battery terminal voltage drop rapidly, which is also the reason for the decrease of capacity.The cocoa battery maintains the appropriate ambient temperature.One of the important factors affecting the service life of battery is the environment temperature, the requirements of the general battery manufacturer environment temperature is between 20 ℃ and 25 ℃.Although the increase in temperature has improved the battery's discharge capacity, the cost of battery life has been greatly shortened.According to the test, once more than 25 ℃, environment temperature rise every 10 ℃, the battery life will shorten the half.At present, the battery used by UPS is generally a valve control sealed lead-acid battery, and the design life is generally five years, which can only be achieved in the environment of battery manufacturer's requirement.There is a big difference in the length of life of a given environmental requirement.In addition, the improvement of the environment temperature, will cause the battery internal chemical activity enhanced, resulting in a large amount of heat energy, will in turn lead to ambient temperature, this kind of vicious circle, will accelerate to shorten the battery life.
