In the daily maintenance of AWP, maintenance and inspection of batteries are essential. Many owners have not used the new equipment for a long time, and the battery is already in a state of loss. Therefore, in the daily use, we must pay attention to the maintenance of battery, and we must also know the precursor of the battery failure.  The battery lights up or swelling is the most common sign, must pay attention to it.

As long as the light is on, it means that the battery has failed, or the battery is found to be swollen (lead-acid battery). Generally speaking, there are two reasons for the battery swelling. The first is long-term charging, The second is that the vent of the battery is blocked, these are battery failures.

The battery poles are found to be corroded or melted.

This is a common situation in lead-sulfuric acid batteries because of electrolyte overflow or lack of electrolyte for a long time. With daily use, the volatilization of lead-sulfuric acid battery electrolyte will gradually decrease. If the electrolyte is short for a long time, the battery life will be reduced, and the storage and discharge capacity will also be reduced. Battery life decreases in winter. All batteries have a certain decrease in battery life in winter. However, the attenuation ratio is different. New lead batteries (including lead-acid and lead gel batteries) usually attenuate 10~15% when the temperature is around 0℃. . Lead-acid batteries that have been used for more than two years, and lead gel batteries that have been used for more than one year are usually attenuated by 30%-40% (under adequate maintenance). In this case, it is difficult for the aerial work truck to complete the workload of daily load climbing. Usually the battery needs to be replaced. The new lithium battery basically does not decay, and its endurance will decrease by 10% to 15% after 3 to 5 years of use at around 0°C.
