Friends who have used electric wheelchairs should know very well that when the electric wheelchair is fully charged, the red (orange) light of the charger will turn green, indicating that the battery is fully charged. But why sometimes the charger still doesn’t turn green after charging for a few hours? Here’s a detailed analysis of why the charger doesn’t turn green!
There are several possible reasons why the indicator light of the charger does not change to green when the electric wheelchair is being charged:
1. The battery has reached its service life: Generally speaking, the service life of lead-acid batteries is about one year, and the number of cycles of charge and discharge is 300-500 times. With the increase of the number of charging and discharging of the battery, the battery will generate a large amount of heat and lack of liquid, which means that the battery’s power storage capacity is weakened. When charging, it has been fully charged, so the charger does not change the green light. It is recommended that the battery should be replaced in time when this happens.
Remember, when charging, the green light of the charger does not change and the battery cannot be charged for a long time when the heat is large. It is best to replace the battery with a new one in time, otherwise it will not only affect the cruising range of the electric wheelchair, but also affect the life of the charger. More importantly The long-term charging of the discarded battery may cause a fire accident.
2.Charger failure: If the charger itself fails, the green light will not change. If your electric wheelchair has not been used for a long time, please go to a professional electric wheelchair maintenance point for professional inspection to avoid causing unnecessary loss.
