Reviews of OPTIMA battery

Currently I run a blue top marine battery, I hardly ever drive my jetta anymore. Will start up fine after sitting for weeks or even longer. Love it!

I have always used an optima red top for all the cars I have owned. Never had an issue.

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 compared the dimensions of both batteries (stock vs Optima) and the Optima is shorter, skinnier, but like 1/4 wider. Optima did not fit, or would not fit without modification to the positive terminal. Ordered the OEM from Keffer.

I just threw in a red top in the G60 and it did not fit well at all. The optima website mentioned some sort of adapters that were supposed to fit on the long edges of the battery to make it fit better under the battery holder, but I did not get any with my battery. I ended up shimming it to get it snug.

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
