What kind so battery life can I expect with my 3 year-old, 45,000 mile LS500?
AGM battery on my 2018 F150 surprisingly only lasted 3 years. Ford service advisor told me that was about average. Battery life on my Miatas with AGM located in trunk was about 8 years.
Am I going to wake up to a dead battery one morning with no warning?

Depends on how the battery is treated. Batteries that get flattened lose their life quicker, whilst those that never get drained below 50% will last longer. I would expect around 5 years and hope for more. If you're worried about waking up to a dead one then get one of those battery jump starters. Worth having one anyway, just in case.

I just changed my battery first time on my 2018 with 90k miles. No issues at all prior. I didn’t even know I needed it changed but it tested marginal on 90k service at the dealer.

With your environmentally controlled garage, I would not be surprised if it lasted you 8-10 years.

Wow - I just replaced the battery on my ES at five years old. No sign of weakness but replaced as preventative measure.

I've had batteries last 8-10 years, and some fail at less than 3. As a result I keep a portable jump starter in the car and don't give the battery, or it's age, a second thought. If ever need the jump starter for anything other than something dumb, like leaving the lights on, or if I get any signs that it's significantly weakened, then I'll change it. Otherwise I leave it be.
