Battery Help

pineyboy · 04-06-2010, 08:43 AM

I have a 2004 Ezgo PDS. It will run about 15min. before the batteries are dead. No power on hills. I installed a battery meter and it will show full charge, but when I push the pedal the hand will move all the way down into the red. When I let off the pedal it goes back to full charge. After charging and letting sit all night here are my battery readings this morning.

One or more of the those batteries are failing the 'load test'. Using a hydrometer, see if you can find a flat or weak cell.

You have yourself 2003 batteries. Its time for 6 new ones, hate to break the bad news to you. I do not recommend mixing 2010 batteries with 03 moldes. Also remember to repalce the battery cables with 4ga at the same time.

With new batteries how much runtime should I expect. I have moderate hills on the road and sometimes get in the pasture field.

The book says 90 minutes of actual peddle time.
Of course, there are many variables .....
