Battery OPTIMA or AC DELCO

I ended up getting a OPTIMA 8040-218 D35 YELLOWTOP from Autozone with a 3yr warranty.

Replaced batteries with red top optimas and all is good Ok so I just wanted to update the thread and mention that I replaced the yellow top batteries with red tops myself that I bought online and the car works fine. No issues. Everything works as it should.

I have an OPTIMA YELLOWTOP....was a little stretch to get it in....just a little. It is UNHEARD OF to have ANY battery here in AZ last for say more than 2-4 years. The Optima has been in the car for 7 years....yeah SEVEN! Best battery I ever had....out of 107 of them!

I'm a fan of Optima, I run them in all of my vehicles. I live in sub zero winter climate. Once I left my car sitting for an entire week during -40F windchill. Everyone else needed jump starts, my car turned right over and came to life. I've accidentally left interior lights on overnight with no issues starting in the morning. On top of the performance is the longevity, the battery lasted a decade with no issues.

My Optima same model as that, is on its 11th year . Yes, non-corrosive. I switched to AGM because I was tired of batteries coming apart at the top seam and leaking acid into the engine bay. I have never had corrosion on the Optima terminals, either. Recently made Optimas have lost their good reputation however, so if you buy one, make sure you can return it if it dies prematurely. I have switched to another brand AGM on the basis of those bad reports.

The old battery I had in mine was an AC Delco, model ACD41-60 (I'm guessing size 41, 60-month warranty). Sticker said 685 CCA, 330 for charge. It's raining outside right now and I don't have any pictures of the sticker for my current one. The Delco battery finally died after being 8 years old. It showed signs of aging and being weak for about 3 months before that, and then one of the cells shorted out, so it had about a 5-amp capacity.

But the battery's been fine. I got a Redtop after the factory battery died, then that Redtop eventually did wear out. So I got an Interstate, and it didn't stay the whole winter before getting shuffled into the Cabby or something that was summer duty/easy to start. I got another Redtop for the bug then and it's been fine.

Every optima battery I have seen in customer vehicles (I'm an auto tech) goes to crap in about 6 months to a year. I think these types of batteries are more sensitive to low voltages. They also don't hold up at all during the freezing winter months.

I had an optima in my garage queen, wasn't even hooked up most of the time(unhooked it till I wanted to drive/work on it). it died 2 years and one month later, with MAYBE 1000 miles on it, no replacement/etc. now it's a doorstop in my garage.

Optima batteries have slowly gone to shit since they were bought by Johnson Controls.
