Battery Bosch or OEM BMW

Bmw e91 318d del 2009, cambiata la batteria originale quest' anno.

low miles 10 yr old vehicle means its possible it has the original BMW factory installed battery. Some of those can last 10 years, I had a 2013 bmw 3 series and in 2022, I finally changed the original battery.

The OEM battery is AGM. If it was an OEM battery it wouldn't be lead acid, at least here in the US. Not sure what you're talking about. I installed mine three years ago and have had no issues despite winters that range from below 0 to summers that reach 100. Fahrenheit obviously.

OEM batteries are made from fairy dust. I still have my original one in my E92, made in 2007. Def recommend getting an OEM battery.

Why on earth would you pay $600 for battery + terminal. I bought recently a BOSCH AGM for $235 and installed it for free by myself after watching a tutorial on youtube.

if you have a costco membership they sell the bosch batteries for a bit more but theyre amazing. 4 year warranty too

I have used Bosch, Panasonic, and now Amaron in my 2013 WK2. Bosch lasted as much as my previous 2 Mopar lasted.

The mechanic I go to gives me Bosch and they last around 2 years if not more. But then they do die within a day when they do.

My experience: Stay away from Bosch.

I've had a couple of issues with my BMW 5-series, I found Bosch batteries don't last as long as they should. I changed them twice in the span of 3 years or so, each time resetting the battery management system with the correct capacity. I changed it to a Deka Intimidator and I'm much happier with it.
