I have noticed a speed slow down on my 2007 Club Car and the yellow light comes on on trips I used to take without any noticeable slow down. The lights also dim when I slow down. I have a four year warranty on batteries but I suspect I have exceeded the 16000 unit limit on the four year warranty. A hydrometer check of the 4 12 volt batteries gave me the following readings: Battery one, 1 cell at 75% charge, 2 cells at 25% charge, all others at 100% charge; Battery two, all cells at 100% charge; battery three, 1 cell at 75% charge and all others at 100%; Battery four, 1 cell at 75% all others at 100% charge.

Can I just replace battery one without having to spend the money for a complete new set of batteries? Should I continue using cart as is until it becomes apparent I can no longer get home from my longer trips? When I do replace all four batteries should I replace with 4 12 volt batteries or replace with 6 8 volt batteries?
