Best Battery Replacement?

[sledaddict73]

My AC Delco in my 2007 Tahoe LT is dying. I have read several posts on here about replacing with DieHard AGM or even Optima Batteries. I also read about a reflash that may fix a drawdown issue with this vehicle. Well, I don't know that the reflash was ever done, but the battery has been fine until recently. If it struggles to turn over, when it does, the clock resets and the temp controls come on with the AC running. Could someone please recommend a good replacement battery? I have read to get 800 CCA at least. I don't want to spend an arm and a leg but I want to put a solid replacement battery in this truck. I plan on keeping it until it dies so the longer this will last, the better. If you give me a recc, please include a model #

Thank you everyone for reading the post......DK

If it's the original battery it's definitely time to change it. The Wal-Mart batteries are usually the best price and warranty is good. I would suggest the 3 or 5 year battery.
