Interesting info about the Crown batteries. Kind of surprising really. I haven't seen one failure yet.

OK,..it's time for an update. I've been busy with family stuff over the holidays so I'm just getting back to my Cart problems. One of the 12 v units has one cell that just will not take a charge or hold a charge. The other 5 cells are at MAX and that is why the battery reads 12.7 volts. But when it comes to delivery current,..it is the weakest link and the cart won't make it through one round of golf with a single rider. So I went back down to the dealer and decided I would try one more time to find a used battery that would at least take a charge and hold it.

When I got there they showed me to a stack of 4 pallets, each with about 20 batteries per level and some had 2 levels and that is about 100 used 12 volt batteries. I asked them why so many and they said they were all "Warranty failures & returns from local Golf Courses. They have been non stop busy with warranty work. Again they let me have my pic of any battery. I had a volt meter and my Hydrometer so first I searched the top level for any unit with at least 12.5 volts. Then I used the Hydrometer to check each cell. What I found was that EVERY battery I tested had at least one cell that was deak and 4-5 cells that were full,..which is why they measured 12.5 volts. I went through 50 batteries and every one of them had one bad cell. I finally got tired of testing them and selected out the one that had 5 good cells and the last cell was at least at the middle of Red and White levels.

I brought it home and hooked it up to my 12 volt charger and ran it over night. In less than 6 hours is shut off saying it was at full charge. I tested it and the volts were 12.8 but they hydrometer on the bad cell had not moved at all. Basically that cell did not take any charge.

Yesterday I talked to the service tech guy and he indicated that sometimes the 12 volt trojans come in the door with one cell that is bad right out of the factory and that 95% of the failures they see are one cell that goes bad. More than 60% of the time it is the first cell or the last cell.

I'm running this battery on a "Desulfate" cycle and when that finishes I will do an "Equalize Cycle" and try one more time to charge it. This experience has certainly helped me decide what new batteries to install,...i.e. 8 Volt trojans.

Keep us informed I wonder if that's why club car went back to the eight volt set up there had to be a reason to quit going with 12 V batteries if they were cheaper to install on the cart makes you wonder doesn't it. Okay trigger good luck...........................

So is when it comes time to replace batteries on my 2006 Precedent will one get better service out of a set of 12 volt US Batteries than the Trojans? Is the problem with the brand of battery or the voltage of the battery?

KCR,... I don't think the final answers are in yet. Club Car and Trojan are still sueing each other over the massive warranty issue. As my notes above indicated, at least one dealer is no stop busy changing out "Trojan 12 volts batterys" under the CC warranty deal with the Golf Course owners. For the stakes of batteries I looked at,..that's a lot of do ray me.

I have seen posts other places where one Golf course owner did a comparison test of two carts, one with 12volts and the other with 8 volts and he said that he only got about 60% as much usage with the 12volts and that they would not last for two rounds of golf at his club.

Since my CC tub is compatible with both I am going to make the switch to 8's. I also found out that my 2008.5 already has the upgraded OBC to handle the switch to 8's.

David,...Since you are right there at dealers,..is your company also involved with replacing a lot of 12's under wananty. If so,..what do you replace them with, US Battery or Trojan's. Also,...do you have ANY SUGGESTIONS AT ALL on how to attempt to fix ONE BAD cell. I can't say that cell is BAD,..as the hydrometer reading is at the junction of the red on top and the white in the middle. All other 5 cells are deep into the middle of the Green. On my external charger I have the ability to run an "Equalize" option which is supposed to help balance the cells. The manual says that the battery will continue to deteriate while the cells are not balanced. It also has a mode to "De-Sulfate" the battery and both of these run for a minimum of 24 hrs. As I said above, when I was at the dealer last week I could not believe how many of the 100's of batteries all had at least one bad cell and the other cells were in the green.

The warranty part of it isn't much of an issue with us anymore. Most of the stuff in our area that is still covered under the 4 year warranty is equipped with 6 8Volt batteries. But yes I can relate, I remember what it was like for all of those years with the 12s. An absolute nightmare. As for the equalization chargers and the de-sulfating chargers, I really can't help there. No experience with that type of thing at all. Sorry. Club Car's policy however, if there is still a warranty remaining on a car equipped with the 12 Volt batteries, they want you to replace them with the US Battery batteries. They seem to hold up better... so far
