Battery
Just information for those interested. My 2015 Z51 C7 was delivered to me Nov. 23, 2014 and has the original battery. Had an oil change done on Thur. Dec. 10 and asked the Dealer to check the battery. Battery Rating is 565 CCA, battery registered 655 CCA, 12.68V, and 4.12 mOhm. Battery has NOT been kept on a trickle charger and has seen multiple times of over 30 days not being started from usually twice a year vacations. Again information only for those interested. Battery over 6 years old!

Sounds like it is still in good shape, but you never know when it will hit the end of its life cycle. I swapped mine out when it was 6 years old and still working well, just to be on the safe side.

No real surprise as I've posted here probably a dozen times that a quality battery that matches or exceeds power requirements specified by the vehicle's manufacturer, vehicle's charging/starting system has been and is in good condition, and used/stored in a fairly moderate climate should last 5-6 years. I base this on my buying/selling/warranting literally thousands of batteries in my auto parts stores over the years.
I've never understood why so many automatically replace their batteries at 3-4 years old. Now after 6 years, you are living on borrowed time.

Unless I'm upgrading something I only replace it when it needs it. That includes auto batteries. In 44+ years of driving I've never had an auto battery fail in under 6 years. Most of mine have lasted longer, sometimes much longer. Having said that, my C7 seemed to crank over a little slower this fall. When I take it out of storage next spring I'll load test it and keep an eye on it. Maybe my corvette will be the exception?

In my, not so knowledgeable, opinion, the environment has a lot to do with a battery’s longevity. Here in Las Vegas, where months of over 110* heat, the battery’s life is usually 3 years with 4 years cutting it close. Since I moved here 20 years ago, I’ve had batteries go bad in less than 4 years. This was on a C5 and a C6. I now have a 2018 Grand Sport, and will probably be replacing my 3+ year old one. But, to each his or her own.

Good to know. Mine just turned five years old and has been on a CTEK when not being used frequently. I still decided to replace it this month to ensure another five to seven years of no trouble starting. After more than fifty years of car ownership I’ve learned it is a matter of WHEN not IF a battery will fail.

I replaced my factory Vette battery at 3 yrs even though not having problems. I use a battery tender. My AAA battery in my Sonata failed in the garage at 32 months. 36 month full warranty. Had it replaced at home - no charge. Southern Arizona heat is hard on batteries. That is why a tender is on my Vette. Do not want unexpected problems with the Vette battery being a difficult installation.

Here's why I changed the battery in my 2014 at 4 1/2 years. If the cost to buy a new, 4 year, quality battery is $200 (probably less), that averages out to $50 a year. For $50, I'm not going to let my pride and joy break down. Add to that, input from other forum members shows C7s do some weird things when the battery is running down. To me, it's not worth it. YMMV
I'm glad for the guys who have had batteries last 6 years or more. I've never had that happen. I've ridden several batteries to the very end, but the best I've been able to do is get a 4 year battery to last a tad over 5 years. So I choose to replace it shortly after the exp date is reached.

New to me 2015 with 11K, perfect condition. After reading post about being locked out, changed the battery, tried the key in the FOB to make sure it works, car is parked with battery tender plugged in, hatch down but not latched and windows opened. In the garage for most of the winter now.
Battery in my 2006 Kubota is original but I can't be locked out and if it dies, it is in my yard. It only pays to be cheap when it makes cents.

I bought my Corvette brand new off the lot Feb-2018. Before test driving, they had to charge the battery. I knew it was an omen. FFW to APR-2020 and the battery dies. No warning. No "low battery" notifications. Just dead. It was charger kept during storage. Chevrolet was going to replace it with a lower CCA battery gratis, no thank you. Bought a H6 Optima yellow top for CCA and deep cycle instead. I'm happy (again, subjective).
