The importance and difficulty of battery maintenance
With the progress of technology, valve-controlled sealed lead-acid battery with its light weight, less occupation, no acid fog pollution, less maintenance work and other outstanding advantages, large-scale replaced the former acid-proof battery. Valve control battery in the outstanding advantages, but also bring innate shortcomings, such as: capacity is difficult to test, can not add water, floating charge pressure, use environment requirements are high, and so on. So the battery after put into use, as the design of the battery before delivery, tooling equipment, quality control, etc., as well as the pressure setting of floating charge in use, using the environment temperature, etc., can lead to active substances, worse, the phenomenon such as the positive grid corrosion, sulfide, which makes the whole battery capacity loss, voltage difference inequalities, and monomer battery backward, and so on and so forth. This will bring great hidden trouble to the safety of production, when the grid fault needs battery power supply, the battery can not put out of the vicious accident.
Valve - controlled sealed lead-acid batteries can be designed to last 10-15 years, some even up to 20 years. It has the advantages of small volume, large volume specific energy, no pollution, no need to add water during use and relatively simple maintenance. But in the field of communication in the actual use of a variety of problems, will make the battery early failure. In the practical application in recent years, the communication interruption events caused by the fault of the accumulator frequently occur, which poses a threat to the power supply of the communication power. However, with proper maintenance management, the battery life can be improved. With the deepening of the maintenance system reform and the gradual implementation of the centralized monitoring system of power supply, the traditional onsite on-duty maintenance of a single specialty has been changed to the integrated maintenance with few people and no one on duty. Maintenance personnel decrease, equipment maintenance is increasing, the traditional battery maintenance test method has been difficult to meet the needs of maintenance, therefore, combined with the current communication maintenance mode and maintenance means, determine efficient and accurate comprehensive test method to judge the battery is increasingly important.
