You are correct because we all know high level corporate CEO types that have to fly all over the world do not have time to replace a battery in their 15 year old truck with over 350000 miles on it.

How long did your OEM car battery last?

Mine just died in the Home Depot parking lot, but to answer your question it made it almost 7 years, so no complaints on the lifespan.

Best advice I ever got from the owner of my auto service provider is to replace the battery every 3 years as the average life of an auto battery in the in the Deep South is 3 1/2 years. Never been stranded or inconvenienced with a “dead” battery in 20+ years I’ve followed this practice.

This is not a terrible strategy in the South for lead-acid batteries.

I've gotten as little as 3 years and up to 5 years in the past. At least if you replace every 3 years it's on your terms, not who knows where.

The newer AGM batteries on newer cars might be an exception. If the charging system is designed for an AGM they can last much longer. I have a 2018 F150 that I changed the OEM AGM battery out at 5 years just as a matter of "it was time".

I do this as well, every 3 years (or even slightly before). The incremental cost is small compared to dealing with a dead battery at an inconvenient time.

Wife's 2020 CRV still has oem battery. I bought a $60 jump pack from Costco and showed her how to use it, if the CRV wouldn't start. CRV (with stop/start) has EFB (Enhanced Flooded Battery): An upgraded, higher-durability version of a standard wet-cell lead-acid battery. It features a special scrim material on the positive plate that improves charge acceptance and provides roughly double the cycle life of a conventional battery.
