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.
The nice people at Optima would love to hear from you.
I put an Optima Yellow Top battery into my 2018 OB 3.6R because the CCAs of the stock battery were pitiful (490 vs 720). Maybe check out other brands aside from Duralast? Also, get something that’s way beefier than the stock battery, especially if you live in hot or cold climates.
I bought an optima just because it and it's custom hold down looked cool. Unfortunately I let it sit with no tender for over a year and it discharged almost completely. I've been able to nurse it back and it is functioning at this time, but not sure it will hold a charge. We will see. I'm happy with it otherwise.
Haven't been impressed with the quality of optima over the last 5ish years.
Have two red tops in my 05 GMC. Sneaky suspicion one is bad. They were new when I got the truck six years ago.
Went to start truck after sitting five days and it was dead. Meter showed 12.1 and it charged in an hour which is very fast. Truck would turn over but not run. Checked charge again, primary at 12.4 and secondary at 12.7. Swapped places and truck starts, runs, all accessories work now.
Stay away from optima batteries unless your car specifies an AGM battery because they can be very problematic.
