Battery appearance inspection:
Check the casing: Ensure that the battery casing is intact, without any protrusions, leaks, damage, or signs of corrosion. These issues may be signals of decreased battery performance.
Voltage detection:
After charging test: After charging the battery for two hours, check the voltage of each individual battery every 20 minutes. If the measured value is lower than 13V, it may indicate a fault in the battery.
Discharge process detection: During the discharge process, test the voltage three times every 10 minutes. If a battery discharges significantly faster than others and the voltage is below 10V, it should be considered a problematic battery.
Dehydration and electrode inspection:
Observation of charger indicator light: If the red light of the charger remains on after 3 to 6 hours of battery charging, it may be a sign of severe dehydration of the battery.
Electrolyte hole observation: Open the battery cover and observe the six electrolyte holes. If the color appears black, it indicates that the lead powder on the electrode plate has fallen off, and the battery has lost most of its electrical energy and needs to be replaced.
Through the detailed testing methods mentioned above, the health status of the electric forklift battery can be effectively evaluated, and timely measures can be taken for maintenance and replacement to ensure the normal operation and work efficiency of the forklift.
