The traction batteries used in electric aerial work platforms are generally ordinary lead-acid batteries, and its important advantages are stable voltage and high cost performance. In daily use and maintenance, the following aspects can be done well to effectively prolong the service life of the battery.
Routine inspections are critical
The top of the battery and the terminal connection should be kept dry and clean, free from dust and corrosion, so as not to cause leakage or short circuit failure. If the surface of the battery is dirty, use a damp cloth or brush to clean the top, terminals and connection parts of the battery with a mixture of baking soda and water, and dry it with a cloth to prevent the cleaning solution from entering the inside of the battery.
Check whether the battery cables, terminals, and wires are damaged, and check whether the connection between the battery terminals and the wires is oxidized and corroded. Once found, clean or replace them in time. At the same time, check whether the battery cover is deformed or heated, and if so, deal with it in time.
It is recommended to check the battery fluid level once a week. If the electrolyte level is too low, it will cause damage to the battery plates and separators, resulting in shortened battery life. The method of observing the liquid level of the electrolyte is as follows: Open the filling cap and check the height of the liquid level. If it is lower than the bottom platform in the filling cap, it means that the liquid level is too low, and the liquid should be replenished in time. If its liquid level is parallel to or slightly higher than the uppermost platform in the filling cap, then it is a suitable position.Also read:48v lithium ion battery 400ah
Routine inspection
Add liquid regularly
Generally speaking, if the liquid level of the electrolyte is 10mm higher than the plate, it means that there is no need to add liquid. If the liquid level of the electrolyte has not covered the plates, distilled or deionized water should be added. If too much distilled water is added, the electrolyte will overflow, which will corrode the battery case and cables, thus affecting the service life of the battery.
The frequency of refilling depends on the usage and operating temperature of the battery. Generally, the longer the battery is used, the more frequently it needs to be refilled. Before adding liquid, the vent cap must be removed to fully charge the battery. If the battery plate is exposed to the liquid surface, add water to just submerge the plate before charging, then charge and add distilled water. After adding liquid, the breather cap needs to be reinstalled on the battery.
Add liquid regularly
Norm charging
The battery should be fully charged after each use. Do not discharge more than 80% of the capacity within 5 hours. It should be charged when the power is between 35% and 80% of the rated capacity. Lead-acid batteries have no memory effect, so do not fully discharge them before recharging. A new battery should be recharged after 3-4 hours of use each time. The battery emits gas (bubbling) near the end of charging, so charge it in a well-ventilated area without open flames. At the same time, pay special attention to never charge non-rechargeable batteries.
Canonical storage
Fully charge the battery before storing it, and store the battery in a cool, dry place protected from the weather. Disconnect the device before storage to eliminate the potential danger of battery leakage. The battery will gradually self-discharge during storage. Monitor the specific gravity of the electrolyte or battery voltage every 2 to 4 weeks. If the battery capacity is lower than 70%, a supplementary charge should be performed. Stored batteries should be recharged before installation.Also read:12v lithium ion battery 200ah
Pay attention to safety during maintenance
When checking and maintaining the battery, wear protective overalls, protective gloves and goggles. Do not store any maintenance tools or other metal objects on the battery surface. During use, the temperature of the battery should not exceed 60°C. Keep the battery away from sparks, flames and metal objects. If the electrolyte is splashed on the skin or the eyes should be washed with plenty of water, and if necessary, receive professional medical treatment. If the electrolyte is splashed on the clothes, the clothes should be taken off, rinsed with water and then washed with weak alkaline soap. When the electrolyte leaks to the outside, it can be neutralized with lime, strong carbonated soda or carbonated soda, and washed with plenty of water.
