TXT 36 v state of charge meter

[taylormademan]

I've just started to notice that my state of charge meter is doing some funny things, when I use the cart on the course and when I return the state of charge is showing about half charge on the meter , but after a full charge the meter still show half charge , but when I disconnect and reconnect the power wire it then shows full charge , not sure if there is a problem or not.

Can any shed some light on this or is it some thing to be worried about or not.

Check the carts battery voltage with a meter when the state of charge shows half charge. You may have a problem with the batteries, charger or the state of charge indicator. Is the meter one with the lights or the pointer? More information would help.

Not sure what the voltage is after a round of golf , but is about 38-40 volts charged. Also I've noticed that the batteries are using a lot of water as well.

I'll check next time I go out and just before I recharge.

Took the cart out for a round , the state of charge showed full charge at the start,then on my return the state of charge showed 1/2 - 3/4 , I measured the voltage (37VDC) I then disconnected and reconnected the meter and it then went back up to full.
Am I going crazy???
Can some one explain to me is there any thing special about a state of charge meter. I just took it as it measures the voltage of the batteries and displayed the LED to indicate the voltage.

if its a factory style curtis led bar soc meter, i believe you you should disconnect it and reconnect with batteries fully charged.

That particular meter resets its self each time you recharge...... it also resets itself to full every time you disconnect it & reconnect. Using lots of water, sudden low readings ..... you may be having a battery problem. Grab a handheld DVM and see what all the batteries read 12 hours after a charge. Post the readings here.

Thanks for that, I could have a battery problem but the cart isn't showing a change in performance but then again the batteries are stamped A8 = Jan 2008

08 batts ! You are running on borrowed time , those batts r prob. On there end of life cycle , however those led type meters are not very accurate
Do as Scotty says measure batts after 12 hr off of charger and post

I measured the batteries off the the charger 39.7 VDC but after about 5 mins they had dropped to 37.2 VCD .

Also after about a little more than a 12hrs on the charger , it was indicating 80% charged.(Delta Q charger)
