Battery OPTIMA or OEM Mercedes

I have run an Interstate battery without issues for the last year, but recently switched to an Optima Red Top. Although I had to get creative in mounting the fuse box on top of the battery, it is nearly 200-300A more than the Interstate in regards to CCA and CA. I am highly impressed. My Escort 8500 has a built in voltmeter. When I would sit at idle with the Interstate battery with all accessories running (lights, A/C, radio) and with as hot has it's been as of late, I would get a low voltage warning (10.5 VDC) when it activated. With the Optima I have yet to see one.

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.

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.
