Re: My merits power chair is two years old but never been...
Batteries don't like just sitting around, they like to cycle that is discharge and charge. Yes you most likely need new batteries. Long slow charging is best for batteries, I would give them 8 to 12hrs.

Whenever you need to charge your power chair or scooter get into the habit of charging overnight. The battery level indicator lights will tell you if your chair or scooter needs charging. Whenever the lights are down into the yellow and especially if they are in the red. If you have the off-board charger, plug the charger into the charger port in the front of your joystick and then plug the charger into the wall socket or turn the on/off switch on and let it charge overnight. When you get up in the morning the charger should have a red light(power) and a green light illuminated (indicating fully charged) Always turn the charger off or unplug it from the wall socket before you unplug it from the chair or scooter. Never have the power on to the charger when you plug or unplug it from your chair or scooter. Whenever you get new batteries always give your batteries a full charge before use and then if you use the chair daily charge it every night. If you do not use your chair or scooter daily charge it at least once a week. Never leave the charger plugged in and on for more than 24 hours. Your batteries should last you 3-4 years if you charge them correctly.
I had same problem. I found a Zip Tie had dug in the wires that only effected the charging not the controlling part. Till the Zip Tie dug in farther, till it cut another wire, preventing the chair to move. That's is when I discovered it. After finding this out, my old batteries were probably good. I just assumed it was their end of life
Check the charger output to verify whether or not you have a bad charger using a voltmeter. These smaller batteries are notorious for having a short shelf life and poor quality control from the manufacturer. Load test the batteries after you verify you have a working charger that will bring the batteries up to the proper voltage first.
perhaps since your chair is over 2.5 years old you have underlaying problems such as motorheatup or excessive drag per a locked bearing or a bushingtrhat is out of lube.somebody needs to at everything that moves thathas to do withload carry,or powertrain.
sking the off board charger is a 5 inch by 3 inch rectangular box with a power plug on one end and a round silver 3 prong plug on the other. The charger plugs into the charger port located under the front of the joystick. Plug the charger plug into the joystick and then into the wall socket. When it is fully charged the light on the chrager will turn from yellow to green. Unplug the power from the wall socket first then unplug from the joystick In ither words always have the charger unplugged when you plug the charger up to the chair Now if the chair has an onboard charger there should be a power cord that just plugs into the chair usually somewhere in the rear of the chair all you have to do is plug it into a wall socket and charge away Hope this helps you
Ranch well the red flash indicates a low battery and the 5 flashes indicate a bad left brake. Now try charging the batteries until you get a green light on your charger then turn on the chair it shouldn't flash the red if the batteries are accepting the charge. If your batteries are 2-3 years old it could be time to change them. If Medicare paid for your chair then they will pay most of the repair costs. You can contact your provider for help or a service company like Roadrunner Mobility @ 1-800-467-2668 or Repair Xpress @ 1-877-581-3733. If Medicare did buy the chair then you are eligible for a new chair every 5 years and yours is almost 8 years old. Contact a local provider that you trust to check into getting you a new chair. Hope this helps you
It sounds like a battery problem more than anything. If it were a fuse, the chair would not move at all. When batteries are stored, they need to be kept charged by charging every couple of week or so (ideally). There may be other problems causing this, such as a short somewhere or a problem with one of the motors/brakes/electronic componets draining the batteries, but I feel this is unlikely given what you have described. I would have the batteries checked at a dealer with a proper battery tester. Preferably have the charger checked at the same time. We use a specific battery/charger tester in our shop that is connected to a computer and will give a graph of the battery/charger condition. This way there is no arguments as to whether the batteries or charger is faulty. Hope this has helped.
