I’m about to own a car with an AGM battery installed in the boot.
I’ve read that AGM generally have long lifespan when installed away from heat such as the engine bay. Does anyone have experience with AGM in boot but with their car parked under hot sun about 6 hours each day? How does the AGM fare in terms of lifespan? |

The battery design with auto start/ stop in mind, if not using auto start/stop can last you many years. My F30 last me around 7 years.

Thanks for sharing your experience. In my case, I’ll be using the start stop feature. Your AGM lasted for 7 years without using start stop feature was with parking under hot sun daily? |
