2002 IQ cart. Charger will not turn off. Plug charger in and after 10 sec delay it will start charging at 15 amps. After 17 hrs of charging it had 3 amps I unpluged it.I thought charger was suppose to turn off after 16 hrs.I don't know what to do. Any help or information would be appreciated!

What year are the batteries??

can you take a readind of each battery and tell us what the volts are
and the volts of the whole pack

You have a bad battery,the charger wont shut off because the batteries are not up to a full charge and the computer needs to have the charge to a certain point for it to shut off.In other words it does not know if the glass is full or not.Hope this makes sense.

I copied some of Tom's Post and editied some of my battery preaching into a flyer for new battery owners... They forget what I tell them before I get to the end of their drive The battery State of Charge Chart is in this thread. Use that and any cheap meter is better than no meter, to implement this plan

NEW BATTERY BREAK-IN PROCEDURE:
Following proper break-in procedure can increase the strength and the useful life span of your new batteries. New batteries are initially about 75% of their full strength. The following procedure will insure they reach their full potential.
The 1st 10 to 20 complete charge/discharge cycles are critical to insure they reach 100%. New batteries should be charged before use and thereafter as follows:
Plug the charger in and leave it alone until charger shuts off by itself. Then drive to discharge the batteries to 75% battery pack capacity (see chart) Plug the cart back in and repeat the charge cycle.......It is very important you let it charge until it is completely done. Repeat this for the first 10 - 20 cycles......by the 12th cycle you will notice a difference in power, speed, and run-time.........I have never had a customer say they have not noticed the increase.
Most importantly, NEVER run the battery pack down below 50% of capacity throughout their entire life. Never leave the batteries in a state of discharge for extended periods of time. Recharge the pack once a week if the cart is sitting idle or in storage. And when in doubt, recharge it.
During the break-in procedure, keep an eye on the water levels (use distilled water only). I have seen it take 12 hours or better for the 1st few Charging times. These extended charge cycles may evaporate some of the distilled water.
As the batteries break in you will notice the charge time gets shorter. Eventually going from 12 to 5-6 hours per recharge.

ONCE A MONTH:
Routine maintenance is the 2nd most important thing to insure you get the most use out of your new battery pack. It is critical that you get into a routine of spending 10 - 15 minutes a month to keep the cable connections clean and check the water levels. Proper water level is critical. Dry batteries die quickly.
Keep the Distilled Water level up to the bottom of the fill hole sleeve or a half inch above the lead plates. Do not fill to the top.
Use a hard nylon brush to remove any visible corrosion. Carefully check that all of the cable connections are tight. Loose connections cause arching which will melt the soft lead terminals. Spray-on Battery Terminal Protector is available from the auto parts store and greatly reduces corrosive build up.
I hope this helps you get the most use possible out of your battery investment.

Golf cart batteries should not be drawn down below 50% capacity. AND new batteries require special break-in procedures, found on this website....
of the other threads thought it might help.

I found that in another thread and thought it might help. I know when I put my new batteries in that my charger did not shut off after 16 hours for the first few charge cycles but the charge time did start dropping as I got them broke in.
