The battery in a diesel generator set is an important part of its starting system, which is responsible for providing the necessary power for the starter motor to ensure the smooth start of the generator set. However, in actual use, the battery may encounter a variety of failures, affecting the normal start of the generator set. Here are some common reasons that may lead to diesel generator set battery failure:

First, excessive discharge

Over-discharge of the battery is one of the main causes of its failure. When the generator set is not used for a long time or when the load is too large, the battery may be damaged due to excessive discharge. Over-discharge will lead to a decrease in the concentration of electrolyte inside the battery and sulfation of the pole plates, thus reducing the capacity and performance of the battery. # Diesel engine #
Insufficient charging

Undercharging is also a common cause of battery failure. If the charging system of the generator set has problems, such as charging voltage is too low, charging current is too small or charging time is insufficient, the battery may not be able to get fully charged. Long-term undercharging will lead to a gradual decrease in the capacity of the battery, or even complete failure.

Third, the electrolyte problem

The electrolyte of the battery has an important impact on its performance. If the electrolyte concentration is too high or too low, or the electrolyte contains impurities, may lead to battery failure. Too high electrolyte concentration will accelerate the corrosion of the pole plate and reduce the life of the battery; while too low electrolyte concentration will lead to a reduction in the capacity of the battery, unable to meet the starting demand. In addition, impurities in the electrolyte may block the pores of the plates, affecting the charging and discharging performance of the battery.

Fourth, the impact of ambient temperature

Ambient temperature also has a great impact on the performance of the battery. Too high or too low a temperature may lead to battery failure. In a high-temperature environment, the electrolyte of the battery is easy to evaporate, resulting in a drop in liquid level, while the plates are also susceptible to corrosion; while in a low-temperature environment, the electrolyte activity of the battery is reduced, charging and discharging performance will be affected.

V. Mechanical damage

The battery may be subject to mechanical damage during transportation, installation and use, such as vibration, collision and so on. These mechanical damage may lead to battery shell rupture, electrolyte leakage or short circuit and other faults, thus affecting its normal use.

Sixth, improper use

Improper use is also a common cause of battery failure. For example, a long time the battery is in a state of discharge without timely charging, or in the charging process is not in accordance with the provisions of the charging current and charging time for charging, may lead to battery damage.

In summary, the causes of diesel generator set battery failure may involve a number of aspects, including excessive discharge, insufficient charging, electrolyte problems, ambient temperature effects, mechanical damage and improper use. In order to avoid the occurrence of battery failure, we need to strengthen the maintenance and repair of the battery, regularly check its condition and carry out the necessary repairs and replacements. At the same time, when using the generator set, also need to pay attention to the correct use of methods to avoid unnecessary damage to the battery.
