How long can lead-acid batteries last?

The inspection and protection of storage batteries are essential for the protection of storage batteries. Whether it is manual operation protection or active monitoring management, it is aimed at timely detecting abnormal faults of individual batteries or equipment system faults that affect the charging and discharging functions of batteries, actively adopting corrective measures to ensure the stable and reliable operation of the power supply system. The view protection of the battery is divided into daily protection, quarterly protection and annual protection. Daily protection to ensure that the appearance of the battery is clean and boring; often pay attention to the ambient temperature of the battery system and the change of the appearance of the battery; often check the online floating charge voltage of the battery and the floating charge voltage of the battery pack (total terminal voltage), and compare them with the panel, and proofread them if necessary. Ensure that the battery cabinet or battery room is clean, ventilated and perhaps well-lit. Quarterly protection visually check the cleanliness of the external appearance of the battery, the intact condition of the shell and cover, the appearance of the battery for bulge deformation and other changes, and the battery for signs of overheating. Every quarter, at the consistent detection point of the battery system, the ambient temperature of the battery system and the average temperature of the representative system shall be detected and recorded. When the temperature is lower than or higher than 25 ℃, the temperature control system shall be adjusted. If there is no temperature control system of the device, the floating voltage shall be adjusted.
