Battery OPTIMA or OEM Mercedes

I recently switched to an Optima Red Top 35 Series which has 720 CCA.

Optima is a great battery if you're running heavy-duty sound systems.

Optima is very good, Run them in all my cars. Hold their charge well in my chilly climate as well.

Optima batteries tend to last pretty long because they use AGM over lead acid

Been running red tops for 2 years. been fine so far.

2007 EOS VR6 6 volt Optima battery replacement Just following up to help out anybody else grappling with this expensive battery situation. I bought two of the red top Optima 8010-044 batteries on Amazon for $189 each and replaced the absurd $$$ yellow ones with no problems whatsoever. All I did was buy a battery charger and hooked it up to the jump points under the hood before disconnecting the old batteries, it was enough to retain all settings. To sum up, don't worry, it's a super simple operation that in no way requires an expensive trip to VW service. I will update if any problems arise as it's only been about a week as of this writing.

Used redtops for years. Had a couple go bad, but 3 year free replacement warranty solved that.

Optima has been garbage for about a decade now, ever since they were bought out and production moved out of the country. Quality immediately took a huge dive.

I'd be more concerned about the Optima battery - they have been crap quality for years now. Probably better than VW OEM junk though.

Purchased one a few years ago, bad a year later and yes I have a good battery tender.
