Dear, I need change battery of my M3.

I have a new model battery version SP306. May I use it?

Operation istructions of battery SP306 suggest check BIOS version, because it must to be V18.01.10 (M4) or V22.01.07 (M5)... 

If I try to upgrade BIOS of M3, lastest version available is V14.01.07 ! 

Thanks

Alex

Hi Alex,

as far is I know, the SP306 can not offically be used is PG M3, at least there is an offical post in german forum, link below (maybe you can use translator).

Nevertheless, there is stated tat only batterys SP304 and SP305 (both discontinued) could be used with PG M3.

Maybe it is worth creating an support request in this regards to receive official information.
