Which Battery
Is either a DieHard Gold or Duralast Gold OK for my '05?? At the same price of $219 wondering if they're the same manufacturer with a different name?? Other suggestions???

DieHard, Duralast, and Everstart are made by Clarios. Match up all 3 by CCA, etc and buy the cheapest

Thanks everyone for the advice. Crazy, bizarre thing happened....removed the center console to prepare for a torque tube rebuild and after unplugging the seat heater switches, 4-way flasher switch, traction control switch and cigarette lighter plug wires the car wouldn't start. Interior lights came on, green light on start button, no dash lights, no door poppers, but radio stayed on!!! Disconnected the battery ground, reconnected it, same thing. Hooked back up the console, same thing! Thought the battery had died as I hadn't started the car prior to all this. Reached out to Dano523 on the site and he suggested removing both cables at the battery and touching them together to bleed off any possible "float" voltage that could be screwing with the BCM. Reconnected the battery and varoom....started right up!!! How bizarre is that!! Took the console back out again with no problems. Guess my battery is OK after all!! However I should buy one in the near future as it's 3.5 years old. Thanks to everybody who chimed in.

Not to Bogart this thread but I inherited my fathers '05 in October last year , he had a AAA battery installed in '21 , keep it on a battery tender when not driving . Any input on the AAA replacement batteries? I'm a Aaa member so that's not an issue ... haven't had any battery issues or problems just looking at replacing possibly next year or '26 .

AAA has about the best warranty at a good price. Make sure it's the right size (CCA, etc) and replace it with another.

Very interesting.....AC Delco 42 month group 86 (which fits a C6) quoted $146 through local dealer that sponsors our Vette club. That's cheaper than anything else I found with a better warranty as well.

I have been buying from Walmart batteries for decades always look for sale, with good warranty.
