My 36V Battery meter is reading low when the batteries are fully charged. What might the problem be?

Not sure, but it could be that your batteries are not holding a sufficient charge to register as full on the meter. Try checking each of your batteries separately with a multi meter. Each of my (old weak batteries) show 7v dc each when fully charged, and 6v when depleted. On the meter this shows up as overcharged (or near the H in the white CHG area) when charged and halfway down the green area when discharged. Hope this helps.

Hi Shard, my initial assumption is that you do not have the connectors in the right place. The batteries are connected in series i.e. mine are 6volt batteries and I have 6 of them for a total of 36v. So the positive connectorhas to be on the 1st batteries positive terminal and the negative connector has to be on the negative terminal of the last battery. If you have it hooked up that way, one of the batteries might be bad. Bill

check back of gauge with an ohm meter and check the volts. If there is 36 volts there , the gauge is bad.

did you include all the batteries in series when you connected the 2 leads from the meter? if you accidendally missed a battery you would only get 30 volts 2 batteries missed would read only 24 volts.If you have a multimeter/voltmeter check the voltage between the 2 leads that you hooked the battery meter to,fully charged should read close to 36 volts.if your batteries are going bad your charger may show as a full charge but still have less than 36 volts.

It might be that you have the meter connected wrong. Check to make sure the pos connection is on the first battery and the neg is on the last battery. I have the same meter and the needle fluctuates very little. I am thinking about changing to an LED one.

Assuming that the meter worked properly in the past, I would make sure that the wiring connections to the meter are clean and secure. The possibility of corrosion increases with time. If this issue has come on slowly, corrosion may well be the culprit. Good luck.

I just put one on my 1988 club car.it seems to be working fine.i just run wire from +post on meter to + on first battery in the battery bank.run wire from neg. post on meter to neg.on the last battery in the battery bank.hope that help you.

I got a similar unit and when I first plugged it in, it too showed "fully charged". I then unplugged it and checked the battery level, but it instantly showed 0V. So that told me the "full charge" reading was false and the charger was giving me that reading while the battery seemed like an "open circuit" and was not accepting power yet. So I did leave it plugged in and within 1/2 hour it began dropping the reading to show 65% charged or such which I knew was more realistic. So despite getting that "full charge" reading off the bat, it does need the charge time.

Perhaps mine is defective, but a fully charged battery discharges to 0% within a week or two.

You should have an auto loading system on your computer that loads the necessary information in your computer when you plug it into your computer. That is all I did and it worked fine. Check and see if your batteries are both functioning properly.

I think you're using the wrong charge mode to get a real capacity reading. You'll get the correct capacity reading in the Charge/Test mode. Start in that mode then cycle through the display until the screen shows ----- The charger will fully charge the batteries and then switch to discharge mode. At the end of the discharge you'll get the mAh reading instead of the ----- Then the charger will switch back to charge mode. The display will switch to FULL when the cycle is complete. If you just stick the partially charged batteries in the charge mode you'll only get the mAh reading that it took to recharge from that point. I would expect 2000mAh rated batteries to be somewhere near 1900 initially and get closer to 2000 after a few more cycles.

Make sure its fully charged. I only figures this out after testing it out and seeing very short videos of the test. I know there has been some complaints of malfunctioning, but mine works fine.

Test the battery first, if it is low in AMP then this should fix the problem. Sometime, a loose wire or bad connectors can cause the issue...

You would have to determine if the problem is the battery or the charge controller / panel. I would hook up another battery that is some what discharged and check the charge current and voltage coming from the charge controller and panel.

Who knows how accurate these cheap gauges are... Checked mine with my analog meter: slightly more than 12 volts at the battery - perhaps 12.1 or 12.2. 12 volts at the terminals on the back of the gauge while the gauge read a hair more than 12. Yours might be different of course.

Per the manufacturers instructions the meter must be in the on position while charging in order to accurately measure the status of the batteries

You might have a bad battery. A cell can be intermittent and the voltmeter will still read okay, since it doesn't check current. I suggest you test each battery with a battery load tester.

I am only using Battery power and the Batteries are showing full charge However Sometimes they dispense in the middle of the day for no reason at all. I have no idea why these units behave like they do. Let me know if you find out anything I would be interested.

Try moving both batteries to the other side of the charger. If you had them on opposite sides or in the middle I believe the left side as you face it plugged in is the side to use for less than four batteries.

Check batt with volt meter. Less than 7volts will do that. Battery might be hosed. Try the boost mode.

I am no expert but it sounds like low battery power. I found one of my batteries no longer holds a charge even though the charger indicates it is charged. Otherwise check to see if the shaft is not fouled with dust or hair etc. Could be that also. Sorry, best I can do.

Same here. I think it is the auto-ranging function. Turn off the auto-ranging and it should settle down. I have zero variability when set to volts range. Given the price of the meter I decided not to worry about this glitch.
