Battery OEM Chevrolet or OPTIMA

Just did that on my 19 gsw, no battery management extra thing to deal with, just the two connectors and obd11 for coding to fleece (not binary agm). Only issue I have is the battery blanket doesn't fit the bigger size.

I have optima yellow and it’s lasted 150,000 miles so far and not slowing down

As previously stated. I have had an Optima Red Top in my Cabriolet for nearly 7 years and have never had a problem. During that that tiome, the battery sat out of the car for almost a year with only occasional bench top charging and was perfectly OK when put back into service. Also, recently I screwed up and left my lights on. The battery was dead dead the next morning. 1.43 volts present to be exact. Took some time but I was able to bring it back up, and it has been performing well ever since. Optima even has a video out about how to bring back a completely dead battery.

I have an Optima Red Top in my 1990 Cabriolet. I have been very happy with it. It is probably about 7 years old at this time and I have never had a problem with it. Otherwise, I would REC a DEKA branded battery. IMHO, "cheap" batteries are not worth the relatively small ammount of money saved.

I'm on my third battery and was thinking about upgrading it to something more reliable, like an Optima.

When I was running two amps 2 12s eight speakers inside head unit capacitor and a built motor I use the yellow top with good success

The red top really isn't that special and optima's tech in general is more beneficial in regard to durability than current delivery.

I also have an 18 and replaced factory with an Optima Yellowtop. Did not last long at all which sucks, was excited to try a battery I've heard so much good about. Went back to OEM since I didn't want any headache and it lasted me quite a bit the first time. Seems like Optima has declined in quality over time.

Replaced my OEM battery with a yellow top and it lasted less than a year. Complete junk imo.

When I worked at the auto parts store, we warrantied a lot of Optima’s. I’d be careful before dropping money for one.
