My 2007 Vw EOS uses twin ( double in seris) 6 volt spiral cell optima batteries stock from from the OEM factory. All V6 EOS received these batteries from the factory stock. ( the turbo 4 cylinder uses a convernional single 12 volt battery)
I need new batteries But at the dealer they are $500 just for the twin 6 volt batteries , not including install ( about one hour of time) I found out that optima the manufacturer sells the optima 6 volt twin batteries for about $300 at any auto parts store and even summit racing sells them new, BUT they are the red top and the dealer battery is a yellow top. Optima ONLY sells the yellow top in 6 volt to VW directly and does NOT and will NOT supply the aftermarket with 6 volt yellow tops. MY QUESTION IS.... has anyone with the V6 EOS used the RED top optima instead of the dealer yellow top optima ? any issues ? I called optima and they said that the yellow top maintaines a more steady operating voltage which the VW computer may need to aviod error codes for lower or unsteady voltage that may occur with a red top.
ANY input from senior technical people on this. ?? I want to save some cash and put the red tops in myself.. I can be reached directly at email@example.com
