Deka batteries. I’ve turned wrenches for twenty years and they’re the only ones that still consistently test far above their rated capacity when new. I have one that’s 7 years old and just installed one in my other rig last year.
A lot of people say the Optima is not a good battery anymore, but I continue to have good luck with them.
I replaced mine at age of 5 and half year, just to be sure - I am leaving the car at airport for 5 days regularly and I did not want to have another trouble solving in my life.
Price was 54 Euro. I have used Yuasa 5000 battery.
Old battery was sitting in garage and has swollen within week and lost voltage.
Just got the notification on my 2019 m3p. Scheduled an appointment for Tuesday. 6 years and 1 month of ownership 77k miles in Ohio. Pretty good longevity if you ask me!
Just replaced battery as EV had stopped working, and the battery dealer said it was. Good battery for hyrbids (Exide X40DPMF)
I replaced the battery with an optima battery brand new I assume the high quality battery. If the battery was a problem would fix it but it did not and now I’m back to square one
I had a Red Top Optima battery, but it’s so dead that even my NOCO AGM charger won’t recognize or charge it.
The OEM battery was junk and crapped out the next day after I got home from purchasing it.
replace battery twice..something is draining it..and 3 x not starting...had to use a jump starter to get it to turn over... no codes registering and dash indicators are not helping..once I get it running all warnings disappear....so I drive around with when is it going to happen again....
Yes, my 2021 battery died mid 2024. No warnings, no abnormal behaviour. Luckily it was still under warranty and the towing and repairing were free.
