My wife has a Quickie V-521 that is full charged however when you disconnect the charger all the lights flash and the reset button is depressed and will notpop back out

You do not need to unplug the large 9 pin beau plug in the rear or the smaller 3 pin molex plug when you charge the chair. Do not unplug them or you will not charge the chair.
Use your charging cord as you describe "plug it into the front, plug it into the wall and charge, then unplug the charger cord and GO". Hope this helps.

Unfortunatly, your batteries need to be replaced. The batteries contain a gel that needs to have current run through it on a regular basis (at least 8 hours once a week) or it will solidify. If you attach the charger, what will most likely happen is the green light will either stay green or go to green after a very short time. The charger will indicate the batteries are full, but instead of being full of power, they are full of crud. Your warranty will most likely not cover replacment as this is due to customer neglect, but your insurance may still cover the replacement if you can wait for the process to go through. Otherwise, you will need to replace the batteries on your own, check your owner's manual or contact the manufacturer for the battery type. Good luck!

Joy When you plug in the charger the lights on the joystick will scroll because of something called charger inhibit which disables the joystick when charging It is a safety feature. Now when you disconnect the charger turn off the chair and then turn it back on you should then get all the battery lights indicating the charge level If fully charged all the lights will be lit. If after you unplug the charger and you still get the scrolling lights then you have a problem with the charger inhibit function in the joystick and it will have to be replaced. Hope this helps you

berry boy Not alot of information but when you say all lights are normal do you mean the battery level lights are all lit up and there are no flashes. Usually when this happens the battery level is too low to make the chair move. When you have the chair plugged up the charger gives enough power to make it move. If you have a digital voltmeter set it 200 vdc then plug the 2 test leads into the 2 outter charger port holes. You should be able to read the battery level and after a full charge should be reading 25-27 volts. Hope this helps

Carla Under the front bottom of the joystick you will see a charger port its a three pin port that accepts the plug from the charger. Always plug the charger into this port with the charger off or not plugged into the electircal socket. Then plug the charger into the electical socket or turn it on. You should see a red light and a yellow light on the charger. When the tellow light turns green the batteries are charged. You should get into the habit of charging the batteries each night if you use the chair daily. Just plug in the charger when you go to bed and turn it off when you get up. If you only use the chair a little then always store it fully charged and then charge it once a week if it hasn't been used. Hope this helps you

The chair is either in freewheel or the number of flashes will indicate an error code to tell what the problem is. Look in your users manual for error codes or contact Sunrise Medical Tech support

Rapid discharge usually is a sign of weak batteries, and they should be replaced if the charge indicates that they are full after charging for several hours, and then dissipate rapidly.

If your not getting a full charge indication after several hours, then you need to check the charger to make sure it is putting out about 28 Volts DC. If it is, then it is for sure the batt's.

The sweeping lights should not occur when the chair is off the charger. They sweep while on charge to tell you that it is charging and you can't move the chair. If they sweep while off the charger, turn off and restart and it should go. If not, call a tech. rep. for Quickie.

3 months is too long for gel batteries to sit off-charge, without being fully charged first, then disconnected before storage.

Your charger is trying to charge, but the batteries aren't cooperating. This chair accepts either the Group 22 or Group 24 gel-sealed batteries. 22 are about 50 amphour, and 24 are about 74 amphour, and will give you greater range. Cost for a set of two of either is going to be about $350 and $450 respectively. Ouch!

it sounds like dead cel in one of the batteries, try having batteries loaded tested.

most chargers have an external or internal fuse, try replacing.
