My scooter wont charge. Light stays red for days of continuous charge. wont run at all. only nine months old.

Mine is an Invacare M51 Pronto Surestep with an onboard Winsunny battery charger. My charging lights are solid red and green/ yellow. Depending on if it is charging or not. What kind of charger do you have?
I have to replace my charger because it is not working. My green light is staying green while charging even though my joystick is showing my batteries are depleting and I just got new batteries. sigh.

The charger may not be operating. If the batteries fall below 20 volts, the charger will not bring them up. You need to take the batteries out and use an automotive charger to charge them individually. It may take several days on the charger for each battery to get them back up to the point where the scooter charger will continue charging.

hi have got a make & model of scooter and the red light u refer to is it on the scooter or the charger............cheers

batteries need replacing

Hi, check all the connections are clean. It could be the charger is done but some batteries when they get left for a long period without charge they won't take a charge any more. Disconnect from power supply before attempting any inspection. Check the wheels are turning freely and not binding. Then last of all the motor may have to be checked.

CHANGE CABLES TO BATTERY

make sure battery cables are secure at battery terminals and clean.how old are the batteries.If the batteries run down fast they are no good.a good way to test them is put scooter against some thing solid and go forward.If the battery indicator drops to o the batteries are no good.It takes about 10 hours to charge the batteries

i had the same problem with mine and it ended up being that one of the batteries was bad, there are two 12v batteries wired in series under the seat, usually you can tell which one is bad by looking at them, one of the batteries will be swelled up

Make sure the free-wheel lever is engaged and the charger is unplugged from the scooter before you try to turn the scooter on. If the battery gauge goes up when you turn the scooter on and there are no beeping sounds you should be good to go.If the battery gauge drops to the red when you try to accelerate slowly, your batteries are shot. (Typical replacement in 24-48 months).If there is any beeping when the key is first turned on then there is a problem and the number of beeps indicates the problem found by the computer during the POST.

A flashing red light orLED on most mobility scooter chargers means the Batteries have a defect as mostchargers also test the condition of the batteries. This has happen becausemobility scooters batteries loose charge when not in use, and need a maintenancecharge at least once a month (best once a week). If this is not done batterieswill fail! Get the batteries load tested to confirm that they are faulty,
