Lead-acid battery life is so short?

Inspection and maintenance of the battery. The maintenance of the battery is indispensable. Whether it is manual operation or maintenance or automatic monitoring and management, it is to timely test the abnormal faults of individual batteries or the equipment system failures that affect the charging and discharging performance of the battery, and actively take corrective measures. , To ensure the stable and reliable operation of the power system. The inspection and maintenance of the battery are divided into daily maintenance, quarterly maintenance and annual maintenance. 1. Routine maintenance 1. Ensure that the surface of the battery is clean and dry; 2. Always pay attention to the ambient temperature of the battery system and changes in the appearance of the battery; 3. Frequently check the online floating charge voltage of the battery and the floating charge voltage of the battery pack (total terminal voltage). The panel display is compared and corrected if necessary; 4. Ensure that the battery cabinet or battery room is clean and well ventilated or illuminated. 2. Quarterly maintenance 1. Visually inspect the cleanliness of the outer surface of the battery, the integrity of the outer casing and the cover, whether there are changes in the appearance of the battery, such as bulging or deformation, and whether the battery has overheating traces; 2. Test at the unified test point of the battery system every quarter Record the ambient temperature of the battery system and the average temperature that can represent the system. When the temperature is lower or higher than 25°C, the temperature control system should be adjusted. If the temperature control system is not installed, the float voltage should be adjusted; 3. On the battery side Measure and record the total floating charge voltage and compare it with the value displayed on the panel meter. If there is a difference, find the cause and correct it in time; 4. Measure and record the floating charge voltage of each battery in the system. Normally, it should fluctuate within a certain range, such as Find the abnormality, find out the reason and correct it; 5. Do a restorative discharge test, discharge with a dummy load or an actual load, that is, cut off the power supply and use the battery to supply power. After finding that the capacity of an individual battery is low, charge the battery in a balanced manner. If the capacity cannot be restored after the balanced charge, the battery with too low capacity should be replaced. 3. Annual maintenance 1. Repeat quarterly maintenance for all content; 2. Check the connection points between all batteries and ensure that the connection is tight and reliable; 3. Take a few batteries at will for internal resistance testing, because the internal resistance of the battery is wirelessly related to its capacity Therefore, the internal resistance of the battery cannot be used to directly indicate the accurate capacity of the battery, but the internal resistance of the battery can be used as an indicator signal of the health of the battery.
