Battery ODYSSEY or OEM BMW

These were very very well made batteries. They also used to be insanely expensive. Now, BMW knows the game and offers a 2 year warranty, which is pretty low for batteries, but they are very competitively priced.

My 2021 45e usually gets 30-34 in mild southern US weather per charge.

I drive a 2016 f15 x5 40e. After 7 years i still do the same distance full electric, maybe 2-3km less but can be my driving style

I have been driving a 2022 330e since March 2022 and haven’t seen any battery degradation to date. In the NY winter I still get at least 20 miles on a full charge, in the summer 23-30.

I set off to test the X5 battery to see if degradation was better or worse than my iPhone's 10% degradation over one year. We've driven 29,996 miles, 15,296.5 electric. My best all-electric range achieved was about 41 miles when new. After one year, I achieved exactly 41 all-electric miles from a full charge in ideal conditions. Zero percent degradation as measured by this test. It appears temperature and AC/heat use have much greater impacts on range than actual battery health at this stage. Results look better than expected for long term ownership and residual value.

Being designed for industry they have a reputation for much longer life (up to 10 years) and better performance at cold temperatures.

Odyssey batteries have served me well. AGM. My Benz has the battery under the passenger seat so I it’s irritating to change. My last Odyssey lasted 9 years and didn’t fail: I just decided to change it as a matter of maintenance.

I'm on my second Odyssey Extreme (first one lasted from 2017-2022) and they are pretty good. I got the 34R-PC1500T. I give it a charge once every month or two with the Odyssey charger.

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've had a few of the Odyssey batteries... Never lasted more than about 14-18 months before dead. Take a look at these: https://shop.antigravitybatteries.com/products/starter-batteries/automotive/ag-h6-rs/
