Optima yellow top. It's around $300 ish. The last one was replaced after a decade. The new one I have will probably be the last one.
I will second a class 3 Bosch. I have one in a hilly city that absolutely rocks the steeps and has a great battery life. Going on 2 years strong and I've had zero battery issues. It rains a lot here but no problems with the Shimano drivetrain either, just regular maintenance.
Its an AGM battery, once it gets depleted heavily this happen. Just replace it. The factory batteries are made by exide or varta so just seek out a same spec replacement from those brands
Cells in the battery are probably done. Happened to my wife\u2019s accord. Said the battery was fine and wouldn\u2019t charge because she barely drives it since she works from home and recommended we get a battery tender. Come to find out the charge of the battery was fine but the cells were dead which is why it wouldn\u2019t charge. Time for a new battery.
My 2021 with 84k miles was very similar. Even had the auto start fail to restart the car once when it was cold. I just had the battery replaced with the new larger size one and it made a huge difference.
The Bosch has slightly lower Cold Cranking Amps at 330 vs the Yuasa at 360. Also Bosch has 4 yr warranty vs Yuasa 5yr.
Not going to say yes or no,but get a battery check before buying it ???? Bmw warranty covers the battery up 6year or 100.000km,so no more battery warranty.. It has 6 modules to replace(not 1 battery) and last time i checked it was around 1000 per piece without labour. My 2020 330e with 98000km had this check and it was at 84% state of health,so this one might not be looking so great.. but get it checked anyway
The father in law had one & also had battery issues.
I bought a 6v Yuasa battery for my old Harley and it lasted about six months. Would drop from fully charged to 2.5 volts in a week of sitting.
A colleague had it, endless battery problems.
