The Volvo generator set battery stored for a long time must be properly charged before use to ensure the normal capacity of the Volvo generator set battery. Spare Volvo generator set batteries should be regularly serviced and charged and can be equipped with a float charger. Scrub the outside of the Volvo generator set battery with a damp cloth, and wipe off the dust, oil, white powder, etc. on the panel and the pile head (that is, the positive and negative poles) that may cause leakage. In this way, the Volvo generator set battery is often scrubbed, and the pile head will not accumulate white acid-etched powder, and its service life will be longer.
Avoid the Volvo generator set battery to start the unit at low temperature, the Volvo generator set battery capacity will not be able to output normally in low temperature environment, and long-term discharge may cause Volvo generator set battery failure. Normal operation and charging will cause some water in the Volvo generator set battery to evaporate, which requires frequent refilling of the Volvo generator set battery. Before refilling, the dirt around the filling port should be cleaned to prevent it from falling into the Volvo generator set battery compartment. , then open the filling port, add an appropriate amount of distilled water or pure water, do not overfill, take the scale of the Volvo generator set battery plate as the standard, otherwise the internal electrolyte will be discharged from the Volvo generator set battery when it is discharged/charged. The overflow hole of the filling port gushed out, causing corrosion and damage to the surrounding objects and the environment. The actual capacity of the Volvo generator set battery can be detected by a hydrometer.
Open the Volvo generator set battery filler cap and see if the water level is at a normal level. Generally, there will be upper and lower limit lines on the side of the Volvo generator set battery for reference. If it is found that the water level is lower than the lower mark, distilled water must be added. If distilled water is not available at once, filtered tap water can be used as an emergency. Do not add too much water, the standard is to add to the middle of the upper and lower lines.
Check to see if the battery is charging properly. If there is a three-use meter, after starting the engine, measure the voltage of the two poles of the Volvo generator set battery, it must be more than 13V to be considered normal. If you find that the charging voltage is too low, you need to ask a professional to overhaul the charging system. If you don't have a three-way meter, you can use the visual method: after the engine is started, open the Volvo generator set battery and water cap to see if there are air bubbles in each small cell. The normal situation is that bubbles continue to emerge from the water surface, and the more you refuel, the more bubbles will bubble; if you find that there is no bubbles, it is likely that the charging system is faulty. Special attention is that hydrogen will be produced during this test, so do not smoke during the test to avoid danger.
Starlight Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to email@example.com we will pay highly attention on your question.
