OK,..It is about time for a little more update. Back on 1-11-2012 I posted a lot of information about my experience with 12 volt trojan batteries and all the help I got from the dealer. After testing all of those batteries I finally selected what I thought was the best one and it had 5 good cells and 1 cell that was at the bottom of the read,..trying to get into the white section of the Hydrometer. When I got it home I put it on a separate charge using my Vector 12 volt auto charger running at 10 amps. Early the next morning it was showing "FuL" charge. The voltage was at 12.6 and 5 cells were in the middle of the green,..but that one cell was just a tiny bit better than before the charge. Needless to say I was very disappointed. I let it set for 24 hours to see if it would hold that charge and it only dropped to 12.5 volts but the one cell was no change. I hooked it up on "Equalize" mode starting with 10 amps and this runs for 16 to 20 hours and at the last few hours drops down to 2.5 amps. This time the one cell improved a little more so I finally pulled out the one really bad battery in my cart and replaced it with this battery. That day I played 1 round of golf riding by myself,..no other load. It would do fine on level ground and would get up to about 14 mph but was still sluggish on the hills. I made it home and charged it in the cart. The next day I saw it took and held a better charge. The following morning I charged it before I went to golf at about 12. It ran fine and now I was getting more speed. I need to mention that first thing in the morning the Club Car Teck was there to do a complete Service on the brakes drums and brake adjustment hardware. It had been so corroded that every time I hit the brakes they would stick on one side or the other. They took everything off and cleaned and greased the rear place as well as the adjusting mechanism. The clue to this problem was that after I drove the cart one time the cart would not roll even with the key off and the switch in "TOW" position. This is also part of my "Herky-Jerky" problem.

Each day as I use the cart and charge it fully it seems to get a little stronger and the speed is picking up and it is not as dead as before when I get it home. This week I'm going to do a "De sulfate" cycle and run it for another day and then I will do one more "Equalize" cycle to see if it can improve some more.

The final answer is that it will NEVER get near top performance until I get new batteries,.. but this fix may last for a least a couple more months.

One other piece of information is that Trojan has a new 12 Volt battery which is "RED" housing,..not the black,..and the CC teck is saying that they are not seeing the problems anymore. At our club the Pro just picked up 12 new EZ-GO carts and he loves them. They all have 12 Volt Trojans (RED). This last weekend I went down to the "Blackhawk" country club to play too rounds there and they have all new EZ-GO with the 12 Volt "RED" Trojans and those carts run fantastic. "Blackhawk" is a VERY HILLY course with constant 50-60-100 foot hills so there is a lot of up and down. These carts have all kinds of speed and torque.

I'll keep testing but I'm much happier now that I have identified what all of my problems were,.. and fixed them as good as I can,..and of course I'm getting ready to switch over the the 8 volt system.

Those E-Z-GOs you speak of are also running an AC drive system which has far less draw than a conventional DC drive system such as yours. They also are probably leased from E-Z-GO on a 1-2 year lease and have almost new batteries in them. I don't buy the statement that the 12V batteries have improved. I think they're just the same now as they've always been. There's not enough volume inside the battery.

David,...You know more than I do about them. I only was passing on "Stuff" the CC teck told me. Personally I'm switching my tub over to 8 Volts.

One point I left out of my last post was that my cart came from a golf course in the Desert and the underneath, including the brakes, is all corroded. Other than power washing it is there anything I can do to extend the life. Club Car tells me all the bearings are sealed and changing them requires replaceing the entire hub. Is that correct.

Just pressure wash the frame real good. That should take most of it off. After that, use a wire wheel on the end of a drill and brush it all down real good. It'll look brand new. As far as hub bearings go, the answer is yes and no. Yes they're sealed. Club Car doesn't offer replacement bearings. The sell the hub as a complete assembly. However, there's nothing keeping you from knocking the bearings out of it, getting the number off of them and buying new ones and pressing them into the hub. I do it all the time, I just cant remember the number.

David,...Great idea. Are the bearings common enough that I should be able to pick them up at my local auto parts store. I'm not sure I'm having any problem and the cart handles and stears OK. My only problem with the ride is that some of our cart paths have large cracks and the cart sounds like something is loose when I hit one. It really "Bangs". My old Yamaha was a very smooth ride.

Check out all of the spring bushings. You might have some chunky ones that need to be replaced. As far as bearings go, you should be able to get them at any bearing place.

What a Saga!

You are one tenacious dude trying to find a good battery in all those stacks. I would have lost my patience long before you did. Hats' off to you man. Looking forward to your update after reading all this.

I also must say, that being new to actually learning to work on these things, I am so very glad I have a simple old cart. Not knocking yours or other new ones at all. Just that I would be SO lost.

Brushpup.... You are correct,... I spend way to much time trying to fix everything myself. I guess that's what happens when you have more time than money. As far as the batteries I the one I brought back last time has worked great but in the other trojans there is always one cell in each battery that never comes up to full. While the car drove fine playing the last 18 holes by the time I got home one battery had dropped to 9.67 volts and it was that once cell that was virtually dead. So being as sturborn as dirt I went down to the dealer one more time and by the time I got there the trojan battery truck had been there and gone and there was nothing left but a set of Interstate 12 volts. I check them and they seemed great,.. no bad cells at all. I took two and brought then home and intalled. They have taken a full charge and I'm waiting for the rain to stop so I can play 18 holes and test it. If they are good I will probably go back and get the other two and that will give me a full tub of Interstate batteries.

I see the references to the serial number beginning with PQ, etc. My 2008.5 begins with CE....what's the difference between a PQ and CE?

tyj503,... I believe that tahoedawg once told me that the PQ stands for an IQ controller. I think you can look this up on the Club Car web site but I'm not 100% on that.
