2024 M4 convertible

bishop4142 · 12-09-2023, 09:53 AM

I just picked up my M4 and wow what a automobile and this is coming from a 2019 GS Corvette.

I have tons of questions but I'm RTF manual first. However I need help choosing a battery tender. As much as I love BMW I like to avoid the bimmer tax.

Which CTEK should I be looking at and what kind of battery does the M4 have. Can the battery be charged through the cigarette/power port ?

Thanks

Your M4 convt has a lithium battery. The CTEK charger for that is listed below. My old C7 could use the cig lighter. I don't think the M4 can. I attach the charger to the positive battery connector (red) under the hood and the neg to any nearby bolt head.
