I keep mine on a battery tender. I had the battery on my 2016 replaced earlier this year. Even though it still tested OK, I did not want to take any chances as we were going on an overnight trip.

My 2019 GS was purchased new in April of 2018. It is in unheated storage from November 1st until April 1st and spends all winter on the battery maintainer. Same for periods of more that a week during driving season. The battery load tested "good" recently and shows no signs of deterioration. I know that 5 to 6 years is the average life expectancy of the OEM battery so I'll be keeping a close eye on it from here on in but, so far so good.

I would say 5-7 years is the expected battery life. I replaced the original battery in my 2014 after 5 years - nothing was wrong with it but just did a proactive replacement to prevent any problems. I do keep my car hooked up to a battery tender when not being driven.

Since we drive to remote areas with no cell coverage, I used to replace our C5/C6 battery every 3 years (~35k miles). With the C7 battery that isn't exposed to the hot engine compartment, I'm using a 4 year cycle.

2014 Z51....Sold with the original battery in 2021 (no issues) - 7 yrs old, kept on tender
2017 GS... New to me when purchased December 2022...no issues with battery but changed it anyway a month ago... - 6 yrs old but purchased new one as I knew one would be needed soon anyway and why push my luck not knowing if the previous owner used a tender or not.
A 2019 of course would be 4 yrs old...if no issues and it tested fine, I'd probably go 5-6 yrs but test it every year as you would be rolling the dice....

I live in a red zone and replaced my battery at 5 years, just for peace of mind.
Really not hard to replace, but be careful with that tiny black wire. It stayed attached when I did the replacement, but I must have pulled a little too hard on it. After a week of driving, it had worked itself out of the connector, and I started getting the Low Battery warnings.

I've had my 2019 GS since 4/21. Still has OEM battery. No tender and don't think I need one here in the S.F. Bay Area. Still running strong, driven regularly. But I am a member of AAA with 100 miles range. Four (five?) years so far and throwing the dice...

My 2018's battery died maybe a month ago with little warning at around 18k miles. Bought around 15k in October, so there's no telling what it went through.
It's an FLA battery from the factory. Expect 4-7 years out of them. An AGM under normal usage will see 7-10 years, and with proper care taken they can last 10-20 years -- my first AGM from the 90s lasted somewhere around 14 years after being repeatedly flatlined.
It might be worth noting that I never use a battery tender. YMMV.

I replaced mine when it was between 5-6 years old. Noting wrong with it, but I just felt I was on borrowed time and did not want to have a failue at a most inopportune time.
