The battery is good or bad judgment dedicated battery meter, but the general users rarely have such equipment, have only a multimeter. The following points in the maintenance of good and bad points of battery summary judgment for reference. 1, from Appearance judge: observing the appearance without deformation, bulge, leakage, rupture exploded, burned, or without screw connections oxide exudation. 2, load measurement: If no abnormal appearance, UPS operates in battery mode, with a certain amount of load, if the discharge time is significantly shorter than the normal discharge time, charging eight hours later, is not back to normal standby time, determine battery aging . "Super Battery - engine start power" when the engine is equipped with a conventional battery failure and can not be implemented when the battery starts sailing, turn on the power to the internal combustion engine to provide fast energy storage device after pass. Conventional battery works and defects: 2013 to the internal combustion engine-powered equipment used mainly as traditional batteries start power, due to the traditional life of the battery by, storage time limit, the ambient temperature and other factors, will lead to lower reserves or excessive resistance and failure, which could be implemented to start. Also, because these factors are difficult to predict and control the internal combustion engine can not be started at any time may occur and cause a loss Paladin battery sails, especially when a large volume of equipment or used for fire, rescue, military, communications, and other applications of mechanical engineering experience Nissan battery sails may cause very serious consequences of this situation. Traditional batteries reduce the ambient temperature of about 10 ℃ resistance increased 15%, the internal resistance of the battery than normal 25%, the capacity has been reduced to about 80% of its nominal capacity, if the battery internal resistance than the normal 50% , the battery capacity has decreased to 80% of its nominal capacity or less. If the new battery with traditional batteries designed for parallel configuration, then you can release large transient currents, so as to solve difficult problems due to cold start device, while greatly extending the life of conventional batteries.
