Hi All,

as OEM battery are quite expensive can You suggest what are best replacements on the market? Which brand do You recommend?

Try Costco.

The OP has Poland listed…assuming that’s the country and not some city in the USA….I don’t think they have COSTCO there.

A 90AH/92AH/95AH battery is usually a 49/H8 battery class size…so look for the same class size as your oe BMW branded battery. Also, select the same type (AGM/Lead Acid/Lithium/etc).
