Do you know some of the causes of the short circuit of the external battery of the UPS?

How is the UPS uninterruptible power supply external battery short circuit caused? UPS battery short circuit means that the positive and negative electrode groups inside the lead battery are connected. The short-circuit phenomenon of lead batteries is mainly manifested in the following aspects:

　　(1) The open circuit voltage is low, and the closed circuit voltage (discharge) quickly reaches the termination voltage.

　　(2) When the large current is discharged, the terminal voltage drops rapidly to zero.

　　(3) When the circuit is open, the electrolyte density is very low, and the electrolyte will freeze in a low temperature environment.

　　(4) During charging, the voltage rises very slowly and always remains low (sometimes it drops to zero).

　　(5) During charging, the temperature of the electrolyte rises very quickly.

　　(6) During charging, the density of the electrolyte rises slowly or hardly changes.

　　(7) No bubbles or gas appear late when charging.

　   The internal short circuit of UPS uninterruptible power supply external battery has the following reasons:

　　(1) The quality of the separator is bad or defective, and the active material of the electrode plate is passed through, causing the positive or negative electrode to make virtual contact or direct contact.

　　(2) The position of the separator causes the positive and negative plates to be connected.

　　(3) The active material on the electrode plate swells and falls off. Due to the excessive deposition of the fallen active material, the lower or side edges of the positive and negative electrode plates are in contact with the deposits, causing the positive and negative electrode plates to be connected.

　　(4) The positive and negative plates are connected when a conductive object falls into the battery.

　　(5) The "lead current" formed during welding of the electrode group is not removed, or "lead beans" exist between the positive and negative plates during assembly, and the separator is damaged during the charge and discharge process to cause the positive and negative plates to be connected.
