Car is a 2005 BMW E46. Factory/regular battery is a traditional (not AGM) battery.
I've read about some advantages of AGM batteries.
Advance Auto and Autozone both have AGM (and traditional) batteries for my car (H7 size).
Are there any disadvantages or problems in using an AGM battery in a car that didn't use an AGM battery from the factory?
Are there any special maintenance requirements when using an AGM battery?
**BTW Both AZ and AA have disclaimers when searching for batteries for my car: IDK if they'll refuse to install this:
"REQUIRES PROFESSIONAL INSTALLATION; Battery is vented to outside; Computer must be reset; See manual for safe installation; 30 minute Install; Battery in trunk; DO NOT attempt to install batteries in this vehicle. The battery information must be reset in the power management system.; Please inform customers and recommend that they have their battery replaced at an authorized BMW dealership/shop."
I am pretty sure "The computer must be reset / battery information must be reset in the power management system" part is non-sense, as no such procedure is needed in an E46 (I've had regular batteries installed before at Walmart but not at AA or AZ). I think all that resetting/reprogramming stuff is only for E90 gen and later.
