The phenomenon of high electric car battery voltage and Countermeasures long float voltage high or supplementary electric voltage control is too high (greater than 2.40V), will produce the following phenomena:. A large quantity of water, electrolyte temperature, electrolytic liquid density increased, positive plate corrosion is accelerated. b. positive plate will be gradually bent, belly phenomenon. c. capacity it will fall, it will result in the early termination of battery life. Remedy: adjust the voltage control value, adjusted to the float voltage 2.23V / only when the (temperature 20 ℃) ??to add power to adjust the charging current or voltage, or replace the faulty voltage controls.

The main types of lead-acid batteries and automotive batteries purposes: for automotive starter, toy car battery 6v7a, lighting, ignition, etc., which require large current discharge, low temperature performance characteristics. Fixed Battery: Widely used in electric power, telecommunications, power plants, toy car battery, nuclear power plants, hospitals, halls, etc., as a backup power source. Railway Passenger Car Battery: mainly used for train lighting, toy car battery 7.2v, ventilation and other standby power. Traction batteries: mainly used battery car, truck, mine locomotive power, require deep charge-discharge performance, so use tubular positive plate of the battery. Locomotive Battery: mainly used for diesel locomotive starting, lighting, etc., requires a large current discharge performance, so use paste type electrode plate. Motorcycle batteries: mainly used for motorcycle starter, ignition, lighting, etc., requires a large current discharge performance is good. Bicycle Battery: mainly used in electric bicycles, electric tricycles, electric scooters and other power supply.
