Zhengzhou conley of electronic power co., LTD., founded in 2000, professional development, production, sales of 2 v, 4 v, 6 v, 12 v four series and maintenance-free lead-acid battery, gel battery and electronic charger, etc. Products are widely used in security alarm system, fire alarm system, building intercom system, elevator emergency evacuation system, emergency lights, antenna, power sprayers, electronic said, children, cartoon gas mould, washing machine, rotary table, parking lock, flashing lights, traffic lights, dc panel, solar energy, wind energy, UPS, EPS, etc for electrical system.

　　Conlida electronics will introduce you to the lead acid battery repair methods and principles of several methods.

　　1. High current charging:

　　Use large current charging, make big lead sulfate crystals dissolve method, found in the experiments, the method to eliminate the effect of sulfide can only get a temporary, and will lead to increased water loss and are in the process of removing sulfide plate softening problem, cause serious damage to the battery life, now there are very few in this simple method to repair the battery.

　　2. Full charge and full discharge repair (deep discharge repair) :

　　Full charge and full discharge repair method is to take full charge of the battery after full charge, then full discharge repair method. Full charge and full discharge repair method is mainly used to repair the slightly damaged battery. Meanwhile, this method can effectively activate the active substances deep in the battery and increase the battery capacity. It apply mild sulfide battery, high internal resistance of battery, which is the key to discharge must be full, and is to separate each battery fully discharge, fully charge all 1 ~ 2 times, the capacity of the battery can generally get promoted. Full charge and full release repair method cannot be used frequently, up to once every three months.

　　3. Shallow circulation high-current charging method:

　　Battery of sulfide, USES the high current (current) within 5 h rate, for the battery to charge state, control the electrolyte temperature does not exceed 40 ℃ advisable, and then discharge, 30% so repeatedly can reduce and eliminate the phenomenon of sulfide.

　　The mechanism of this method is to flush the surface of the plate with sulfide slightly by using the gas precipitated from overcharge, so that it can be desorbed and dissolved into active substances.

　　This method is characterized by obvious repair of slight vulcanization. However, it is not suitable for old batteries, because the removal of gas to wash sulfates also produces a strong erosion on the active substance of the positive plate, making the active material soft or even falling off.

　　4. Add active agent:

　　Battery of sulfide, add water and sodium sulfate, potassium sulfate, tartrate substances such as mixture, take a few times normal charging and discharging, and then poured out water add slightly high density acid adjustment inside the battery acid to standard liquid concentration, think back to more than 80% capacity restoration success.

　　The mechanism of this method, the addition of these sulfate ligand dopants, can form coordination compounds with many metal ions, including sulfate. The resulting compound is unstable in the acid medium, and the non-conductive sulfide layer will gradually dissolve back into the solution.

　　Using chemical methods, eliminate lead sulfate crystallization, high cost, not only increase the battery internal resistance, and also changed the original structure, the electrolyte after repair is shorter, could the side effect is bigger, the repair rate is about 40%.
