Batteries are charged but the meter reads zero

The green light on your charger indicates a full charge but you know thats not right since you didn't charge the batteries when they were in storage they have dropped so low the charger cannot detect them and provide a charge. The batteries will need to be replaced with new ones. Charge before use and charge for at least 20 days to get them operating at 100% now you will have to use it for those 20 days to get the batteries used to charging charge every night when you go to bed and unplug when you get up in the morning. If you do have to leave the chair for a week or so put up fully charged and charge once a week overnight. If you put the chair in storage again disconnect the batteries from the chair and store with a full charge. Hope this helps you

super hmmm new batteries? well I would check the battery connections because you should be getting power to the joystick. The charger is providing power thru your joystick to be able to turn it on. Now when you plug in the charger are you getting any movement on the meter at the rear of the chair? If not but staying at zero then the charger is not charging the batteries and your batteries are not hooked up correctly. You will have to remove the seat and cover over the base to have access to the batteries check all the connections and make sure that if the plugs are colored that the red and white plug is plugged into the red and white plug going to the front of the chair and that the black and white plug is plugged into the black and white plug going to the front of the chair. If the wiring is ok then get a meter and read the voltage across each battery they should read 13+ volts fully charged. Plug in the charger and read the voltage at the batteries again if charging then you should read 16+ volts. If the voltage doesn't change then the charger isn't working correctly and if reading a good voltage then the batteries are bad and need to be replaced. Hope this helps

amy why did you not keep the batteries charged? even new batteries have to be charged before use. Now plug in the charger and look at the meter with the charger plugged in the meter will show some reading around 4-5 amps. Let the charger work overnight when you get up in the morning fully charged the meter will read zero. Turn on the chair and all the battery lights should be lit. If after charging over night you are still getting one red light then you blew 170.00 and no amount of charging will bring them back. Sorry I wish I had better news. If you replace the batteries charge fully before use and then use the chair some each day and charge nightly for 20 days this will break in the batteries and get them operating at 100%. If you then only use the chair sometimes always put it up fully charged and charge at least once a week If you use the chair for that day charge overnight and it will be ready to use again when you need it. If you are going to leave the chair unattended for 6 months then fully charge the batteries and disconect them from the chair until you need it again New batteries every 6 months can get expensive Hope this helps you

Cathey when you plug in the charger look at the rear of the chair at the meter if the chair is charging then the meter will indicate some amperage reading when it is fully charged the meter will read zero. Also turn on the chair and if the lights are scrolling or flashing it shows that the charger is plugged in. Now if after the meter reads zero (if it ever does) the lights on the joystick should all be lit indicating a full charge. If you aren't getting all the lights and the meter indicated the charger was working then you need to replace the batteries Hope this helps

The battery is fully charged when the gauge reads zero.

bfa After about 8 hours or overnite charging and with the charger still plugged in look under the rear of the chair and the charger lite should be green indicating a full charge if it isn't on and the meter at the rear of the chair is on zero then I would guess you have a bad charger. If you have a digital voltmeter or access to one plug it into the two outter holes of the charger port located under the front of your joystick. Set it to 200 volts dc and with the charger plugged in you should read 27-34 volts. If you don't get that then the charger isn't working and you will be reading only the battery voltage. Hope this helps

The meter is telling you approximately how much current (amps) it is sending to the battery. When the meter moves all of the way to the right it is charging as hard as it can (that would be 6 Amps) which indicates that the battery needs a lot of charging. As the battery becomes saturated with charge, the meter will move toward the left. As the battery become charged, the unit automatically tapers off the current. The meter can indicate as little as little as zero Amps, meaning it is not charging the battery at all - which is the case when the battery is powered up, but isn't even connected to the battery. If it reads zero when it's connected to the battery, the battery is broken and can't be charged.
Since this charger is rated at 6 amps, it will indicate about 3 amps when the battery is about done. It won't normally go to zero because those 3 amps are getting wasted just heating up the battery.

Disconnect the battery, and connect an ohmmeter to the cables.

Start pulling fuses, one at a time, until the resistance that you are reading either becomes very high (more than, say, 200,000 ohms) or infinite. The stuff that fuse feeds is where your drain is.

If there is no resistance measurement (infinite), or the reading is very high, then try this: Charge the battery, disconnect the battery, and see whether the battery still has a full charge after two days. If not, sedimentation at the bottom of one or more cells is causing pwer loss through short-circuiting. You will have to replace the battery.

First, even a fully charged battery may not be working right - VERY common.
Does the camera do this on two batteries, one old and one much newer? (I say this because lithium batteries are good for about 500 charges - if you are over this, the batteries will always read weak...)
A service shop can test the camera and see if the battery is reading correctly. A service shop may allow you to try the SHOP's good battery in your camera and see if it reads right. If OK, you need a new battery.

The service shop can reload the operating data into your camera - I have fixed them this way myself.
If not, the circuit board that handles charging and batteries may run you $275 plus labour. (The board is not repairable)

You are charging. The meter corresponds to the level of charge in the battery. Try setting to 10 A for 4 hours, battery should be half-way up. To determine if battery id dead.. leave battery off charger once it is fully charged...test with a voltmeter after 10 min.....battery should still be above 12v...after1 hour it should still be above 12v...if not battery is spent.
