Owner reviews for battery

I put one in my car and it worked fantastic for 3 years no issues and is still going strong.

I have the Yellow top in my 1983 Scrambler and have had no problems with it. I treat it awful in winter I will go weeks with out driving it and then crank the jeep and go use the winch and lights sometimes idle for long periods and the not drive for a few more weeks. Cranks every time.

Just replaced a Duralast (Autozone?) yesterday in my Silverado. It was from 11/09. It had a pretty good run in several vehicles of mine.

On my Porsche I run an Optima which lasts 7+ years and is a very strong battery.

So we bought a new 550CCA battery and installed it and it started right up. When I pulled the 18 month old OEM battery out, I was shocked at the CCA rating: 356. 356!!!! That's insane.

I like them and that's what I use in my Toyota (Lexus). Had it a couple of years and so far so good. One neat thing about the Optimas is that since it's 100% sealed there's no worry about tipping it or having to wear gloves during transport and installation. It's also lighter.

I've got a '13 R with KESSY and NAV. that had a weird slow start, which made me think the KESSY swt. was worn like another thread mentioned. So I tore it apart and it was dirty on the contacts so I cleaned them. After that it seemed better but the car had 30+K miles and I did get another weird slow start, so I tested the battery and it tested good/charge. I did end up replacing the battery. I haven't had any issues since then. Now at 52K miles.

Some BOSCH batteries used on VW cars last around 2 years or a bit more but cost appropriately.

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.
