F90 M5 main battery

[A8 PMJ]

Hi everyone,

The main starter battery on my 2019 M5 is getting towards the end of it's life.
The original battery fitted is Li-ION battery. I have researched to find a replacement and the lowest price is £911.00.
Can I replace the original Li-ION battery with a Lead Acid battery?

Cheers
Pat

Not recommended as it may well skew the charging system metrics.

Not saying it will, not an expert, just not worth the risk if it all goes wrong.

They are places you recondition these batteries if you do some forum research.

Definitely not a good idea.
