1. Lead acid battery short circuit is mainly shown in the following aspects: 1.1 The open circuit voltage is low, and the closed circuit voltage (discharge) quickly reaches the end voltage. 1.2 When discharging at high current, the terminal voltage drops to zero rapidly.
2. The main reasons for the internal short circuit of the lead-acid battery include: 2.1 The quality of the separator is poor or defective, allowing the active material of the plate to pass through, resulting in virtual or direct contact between the positive and negative plates.
The shedding process occurs naturally as lead-acid batteries age. The lead dioxide material in the positive plates slowly disintegrates and flakes off. This material falls to the bottom of the battery case and begins to accumulate.
Many of the float charge and discharge voltages of lead-acid batteries in UPS power systems have been adjusted to their rated values at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as control of the number of computers and other electronic equipment.
Corrosion is one of the most frequent problems that affect lead-acid batteries, particularly around the terminals and connections. Left untreated, corrosion can lead to poor conductivity, increased resistance, and ultimately, battery failure.
Often, the peak short circuit current occurs within 5 to 15 milliseconds. Without some form of protection such as a fuse or breaker, a short circuit condition can cause permanent damage to the battery. In effect the battery can itself becomes the fuse.

Causes of Short Circuits in Lead-Acid Batteries
The most common cause is the formation of dendrites or conductive debris between the battery''s plates. Over time, the accumulation of lead particles in the electrolyte can bridge the gap between plates, causing a short circuit. Another potential cause is physical deformation or improper handling of the battery, leading to internal plate contact.
