Battery OPTIMA or OEM BMW

Everyone likes to shit on BMW for being too complicated when it comes to having to register batteries with the car, but this is the result. Batteries in other cars die way more quickly.

I just changed my 2018 F36’s battery a few months ago. They really do last a long time.

2016 328i. Original battery still alive and kicking!

The battery on my previous F20 lasted over 12 years before I replaced it last winter. Had enough voltage but bad resistance readings, mechanic advised me to change it for the winter.

I’m just over 10-years on my ‘15 M235i.

BMW i3… loved that little toaster but 80 mile range wasn’t cutting it anymore. I still enjoyed running errands and zipping through parking lots.

Ich fahre im Moment nen BMW i3 von 2015 mit nur rund 15 kWh Batteriekapazität und knapp 80k km runter. Da die eh so klein ist und das Auto auch kein großartiges Lademanagement hat, knall ich (und wahrscheinlich alle Vorbesitzer auch) die Batterie eigentlich so gut wie immer auf 100%, was man ja eigentlich vermeiden soll. Das Auto liegt über den Daumen gepeilt ca. 10-15% (eher 10) unter den Angaben, die man so im Netz findet.

I’m not satisfied with the range (70 miles) or the charging speed (max 19.2 kW via J-1772, taking 4 to 13 hours to charge) of the BMW batteries in my Lion Type C electric school bus.

I purchased one because of my car stereo upgrade, thinking it would be a better choice. Within a few weeks, I noticed that my cranking was slow and labored. It is almost seven months later, and I find myself having to randomly jump-start my car. Note: At first, I was concerned that my audio amps were not turning off properly and checked to confirm that everything was off. I think I may need to go with a different solution now.

I went through 2 of them in my Corvette. The last one was making sizzling noises after I needed a jump from a 200 amp battery jumper. The top of the battery was meled,.Not worth the money. Never again!!!
