Battery Tesla or OPTIMA

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.

Although now I run an Optima Redtop that doesn't need to vent.

I have the model 35 and the stock cover does fit over it: As far as long term, I haven't been super impressed... I've had my redtop die a few times over the last few years, not even from extended use... however it did get rid of issues I had with my lights dimming from the sub and if I decide to drive upside down it supposedly can handle that

Optima started to suck after they were bought out by Johnson Controls. I'll never use another one. I'd buy an Odyssey.

I had an optima yellow top in my Jeep for 3 years. Then all of a sudden a cell died without warning, leaving me stranded in the desert when I went to start it. I will never buy another one. The duralast I replaced it with has been in there for about 4 years now with no problems. It also cost less than half what the optima was.
