Going with Odyssey MK7.5. The one in my Raptor is awesome 3 years old and tests like it was new. Its not lighter but its a great battery. Try Braille batteries.
Owner reviews for battery
For about a month I have owned a 2016 REx whose 60 Ah battery is supposed to get 72 miles. This week I fully charged it and have been commuting four four days without topping up. Today the REx kicked in with the trip meter at 73.3 miles. This was a mixture of city traffic jams and short bursts on the carriageway, mostly with the air con on and mostly in Comfort mode. So I'm pretty pleased.
I've been using an Odyssey 925 in the Miata with no issues. It gets driven mostly on the weekends and a few times during the week but stays on a B&D 2 amp tender when not driven. I've had this setup for about 6 months so far and it works great for my particular situation with a 3rd car.
I got 7 years out of my 2010 6V Red Top in the Porsche which I replaced with another and recently purchased a 12V Red Top for the Bus. Battery is more expensive than standard but getting 7+ years vs 4 makes it worth while.
The Optima in my Infiniti is 10 years old and still going strong but I've read so many bad things about them recently, I would be hesitant to buy another one.
My MK7 is still rocking the Varta OEM battery from 2015 since new, and my MK4 has a "duralast" Gold H5 which has a 1/2016 stamp on it and it is still doing fine.
I have a red top in my 4 motion b6 Passat. I have not had any electrical issues. As long as the optima matches or exceeds the oem battery cca you’ll be fine.
installed new Exide EK950 AGM 95AH to replace same model been there 3years. No change, and also former battery checks to be in nearly new condition still with measured 90AH capacity from fully charged to 10,5v 9hours with 10Amp load.
It was a Varta battery. And dial a battery and car guru provide similar services right? And I only talked about battery prices as the service to come to my place was provided via insurance. Secondly yes I accepted it as I had to go out in a hurry but in my opinion they seem to be expensive when directly compared to their competitors.
I've been seeing the same issue with batteries branded under Bosch and Champion. On several cars, I rarely had to replace batteries, now it seems like it is a 1-2 year thing on any battery. They are dying faster without ability to recharge. I just posted in the Scirocco forums that my 3 year warrantied Bosch battery is no longer holding a charge and its not even 11 months since I bought it. Glad to know that I'm not alone in seeing that engineered battery obsolescence seems to have arrived.
