During the daily maintenance of aerial work vehicles, the maintenance and inspection of the aerial work vehicle batteries is essential. Many owners of leasers have not used the new equipment for long before the new equipment has been purchased. Too. Therefore, we must pay attention to the maintenance of the battery of the aerial work vehicle in the daily use process, and we must also know the precursor of the failure of the battery of the aerial work vehicle.
The indicator light of the battery of the aerial work vehicle is on or the bulging occurs
This is the most common symptom and the most intuitive one. When the battery fault indicator of the aerial work vehicle above the joystick of the aerial work vehicle lights up, it must be paid attention to. As long as the fault light is on, it means that the battery of the aerial work vehicle has failed, or the battery of the aerial work vehicle has been swollen (lead-acid battery). Generally speaking, there are two reasons for the battery swollen. The second is that the vent hole of the battery is blocked, these are the failure of the battery.
The battery pole is found to be corroded or melted
This is a common situation with lead-sulfuric acid batteries because of electrolyte overflow or lack of electrolyte for a long time. With daily use, lead-sulfuric acid battery electrolyte will gradually reduce the volatilization. If the electrolyte is lacking for a long time, the battery life will be reduced, and the storage and discharge capacity will also be reduced.
Battery life in winter drops
All batteries have a certain reduction in endurance in winter, but the attenuation ratio is different. New lead batteries (including lead-acid and lead gel batteries) usually decay by 10 to 15% around 0 ° C. Lead-acid batteries that have been used for more than two years and lead-colloid batteries that have been used for more than one year usually attenuate by 30% to 40% (under adequate maintenance). Under such circumstances, it is difficult for the aerial work truck to complete the daily workload of climbing the load. Usually the battery needs to be replaced. The new lithium battery basically does not decay, after 3 to 5 years of use, the endurance of the battery will decline by 10% to 15% at about 0 ° C.
