The following mainly analyzes the lead-acid battery short circuit caused by excessive charging current, charging voltage of a single battery exceeds 2.4V, internal short-circuit or partial discharge, excessive temperature rise and valve control failure, and summarizes the treatment methods of lead acid battery short circuit as follows:
Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. The water loss increases the maintenance requirements of the battery since the water must periodically be checked and replaced.
CALCULATED VS. ACTUAL SHORT CIRCUIT CURRENTS FOR VRLA BATTERIES “shorted” lead acid battery has the capability of delivering an extremely high current, 100 to 1000 times the typical discharge current used in most applications. Electrical systems using batteries must be properly protected to avoid potentially dangerous fault conditions.
In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge. The dependence of the battery on the battery state of charge is shown in the figure below.
One of the singular advantages of lead acid batteries is that they are the most commonly used form of battery for most rechargeable battery applications (for example, in starting car engines), and therefore have a well-established established, mature technology base.
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.
