How long does it take to fully charge a wheelchair batteries

If your Dynamic DL 4.2i electric wheelchair is experiencing issues where the LEDs are flashing and the chair won't move despite fully charged batteries, there could be several potential reasons for the problem. Here are some troubleshooting steps you can take:

1. Check for Error Codes:
   • Electric wheelchairs often have a diagnostic system that uses flashing LEDs to indicate specific error codes. Refer to the user manual for your wheelchair to interpret these codes. They can provide valuable information about the nature of the issue.
2. Inspect Connections:
   • Ensure that all the electrical connections, including those between the controller, motors, and batteries, are secure and free from corrosion. Loose or damaged connections can disrupt the functioning of the wheelchair.
3. Reset the Controller:
   • Some wheelchairs have a reset button on the controller. Try resetting the controller by turning off the power, waiting for a few seconds, and then turning it back on.
4. Check Joystick Operation:
   • Verify that the joystick is functioning correctly. Sometimes, issues with the joystick or its wiring can affect the chair's performance.
5. Test Batteries:
   • Even though you mentioned that the batteries are fully charged, it's worth checking their voltage and overall health. Faulty batteries can still show a full charge but may not provide sufficient power.
6. Controller or Motor Issues:
   • If the problem persists, there could be an issue with the controller or the wheelchair's motors. In such cases, it's recommended to contact the manufacturer's customer support or a qualified technician for further diagnosis and assistance.
7. Professional Inspection:
   • If the wheelchair is still under warranty, consider contacting the manufacturer's customer support for assistance. If not, seeking the help of a professional technician with experience in electric wheelchair repairs may be necessary.

Always prioritize safety when troubleshooting or attempting to fix issues with electric wheelchairs. If you are unsure or uncomfortable performing the troubleshooting steps yourself, it's best to seek professional assistance to ensure the wheelchair is properly diagnosed and repaired.

You have two good batteries in the green side, the red light means that one or both batteries are not fully charging. Try that set on the other side to confirm. Make sure the batteries and charger connections are clean.
Hope this helps.

is this ref any use ?

be careful over what charger you use as Li-ion batteries must not be overcharged. most have a sensor that detects the voltage and stops charging when the battery is fully charged. This circuitry is inside the charger, not the pin.

I had the same problem I had to replace the batteries problem solved.But the batteries are not cheap

Yep It sure does Why didn't you charge the chair for 2 months? Charge at least once a week if you don't use it daily. Always break in the new batteries by using the chair daily for 10-15 days charging everynite then charge once a week if it sits for that long without use. Always put up fully charged. Do this and your batteries should last 3 -4 years Charge overnite if you use daily and never charge more than 24 hours Good Luck

Jo, nope you are safe. Most of the chargers are designed to cut off and go into trickle charge once they sense that the batteries are fully charged. The problem with overcharging comes after 18 hours or so. You should never leave the charger plugged into the chair for more than 24 hours. On the M51 the charger is built into the chair so just plug it in when you go to bed and unplug it when you get up and you'll be ok. You can check for full charge by looking at the charger there should be a red light and a green light when fully charged. Hope this helps

Charger is charging should turn solid green when fully charged if not the batteries are bad or charger is not working correctly

Hi. Your machine probably has a fault, but I very much doubt that it needs reprogramming.
Are the free-wheel levers in the correct place? Is the machine displaying any fault codes, e.g. flashing LED's and what is the pattern or number of flashes between pauses?
Good luck. Neil.

The green light on the charger usually indicates that the batteries are fully charged and you are ready to go. Does the controller show the batteries are fully charged? Can you operate the power wheel chair for several hours? If so, you are good to go.
When you connect the charger, if the light goes to red to green within a few minutes and the battery power does not last more than 1-2 hours or less, it may indicate that that the batteries will not take a charge anymore and need to be replaced.

Have the batteries load tested. If the batteries are bad they will accept a surface charge and seem fully charged.
