I've got an optima yellow top & it fit w no problem. No modification whatsoever. You just gotta make sure tha +/- (positive/negative) are reversed.
I think we have an Optima in our Mk1 diesel.
Im running an optima redtop 1000 cca. Starts like a champ in -10 degree weather.
The other day I installed my Optima yellow top that was intended for my S10 into the GTI. Had to cram the battery cover top on a bit, but its on there! Funny now the car starts up alot faster. It always seemed like since I got this car it was slow to start, as if the battery was always low...
I upgraded to an Optima yellow top D35 in my GTI probably about six months go..no problems w/ it at all..the batter cover doesnt fit perfect, but you can make it work...i'm runnin bags with dual compressors and also a jl audio sub/amp system so i needed something with more power..which the yellow top has
I do have a Yellow top Optima battery in my VW Jetta MKV 2007 and I just had one problem a little time ago since one of the terminals needed to be tight again... but that's pretty much it, it works just fine.
I've had very good results with mine, and I just get whatever would fit a New Beetle TDI. NBs take a reverse terminal battery and it's nice and compact.
Yup, that's the one. The R is for reversed terminals to make it a more ideal fit for our application. Sadly I couldn't find one locally when I needed it so I got the 34/78. It works but isn't a perfect fit as it does require trimming to get the clips on the distribution block to snap back in.
My dad put an Optima red top in his Porsche 930. He used the exact trickle charger you pictured for storage and because the car is driven only a couple of times per month in the summer. The battery was in there 2 years and I had to scramble late Friday night to install a replacement after it wouldn't start at the gas station (friendly attendant helped me bumpstart it). The battery stopped taking a charge.
Optima started to suck after they were bought out by Johnson Controls. I'll never use another one. I'd buy an Odyssey.
