How to Maintain the Battery of the Generator Set

Mar 27, 2024 | Technical Literature | 0 comments

When the battery of the diesel generator set has not been used for a long time, it needs to be properly charged before use to ensure the normal use capacity of the battery. Normally, technicians will cause part of the water in the battery to evaporate during normal operation and charging; therefore, it is necessary to replenish the unit’s battery from time to time. The first step before refilling is to clean the dirt around the filling port to prevent dirt from falling out. into the battery compartment, then open the filling port and add an appropriate amount of distilled or purified water, do not overfill.

Diesel generator set is a power supply equipment that uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. This is a power generation device that starts quickly, is easy to operate and maintain, has low investment, and has strong adaptability to the environment.

How to Maintain the Battery of the Generator Set

Avoid using the battery to start the unit at low temperatures. The battery capacity will not be able to be output normally in low temperature environments, and long-term discharge may cause battery failure. The battery of the standby generator set should be maintained and charged regularly and can be equipped with a float charger.

Diesel generator battery maintenance methods:

1. Check whether the battery is charging normally. If you have an ammeter, after starting the engine, measure the voltage at both poles of the battery. It must exceed 13V to be considered normal. If you find that the charging voltage is too low, you need to ask a professional to check the charging system.

If there is no three-purpose ammeter, you can use visual inspection: after starting the engine, open the battery water filling cover and see if there are bubbles in each small grid. The normal situation is that bubbles will continue to bubble out of the water, and the more oil will bubble out, the more oil will bubble up; if you find that there is no bubble, there is probably something wrong with the charging system. Special attention should be paid to the fact that hydrogen will be generated during this inspection, so do not smoke during the inspection to avoid the risk of explosion and fire.

2. Open the battery water filling cover and check whether the water level is at the normal position. Generally, there will be upper and lower limit markings on the side of the battery for your reference. If it is found that the water level is lower than the lower mark, distilled water must be added. If distilled water cannot be obtained at once, filtered tap water can be used as an emergency. Do not add too much water, the standard is to add it to the middle of the upper and lower markings.

3. Use a damp cloth to scrub the outside of the battery, and wipe away dust, oil, white powder and other contaminants that may easily cause leakage on the panel and pile heads. By scrubbing the battery frequently in this way, white acid-etched powder will not accumulate on the pile head of the battery, and its service life will be longer.The above batteries are old-fashioned batteries. Our Yongfengsheng generators are now equipped with nano-maintenance-free batteries, which require no maintenance and are more convenient!

4. Normal operation and charging will cause some water in the diesel generator battery to evaporate, which requires frequent rehydration of the diesel generator battery. Before rehydration, the dirt around the filling port should first be cleaned to prevent it from falling into the diesel generator. into the battery compartment, then open the filling port and add an appropriate amount of distilled or purified water. Do not overfill. Use the scale of the diesel generator battery plate as the standard. Otherwise, the internal electrolyte of the diesel generator battery will be discharged/charged.

5. Avoid using the diesel generator battery to start the unit at low temperatures. The diesel generator battery capacity will not be able to output normally in low temperature environments, and long-term discharge may cause diesel generator battery failure.

6. The diesel generator battery of the backup generator set should be maintained and charged regularly and can be equipped with a float charger.
