A Genuine BMW battery, or a quality German made replacement is your best bet. Most F10's require a 950cca 105ah AGM Battery and registration with the IBS is absolutely critical. This is routine maintenance, no different than tires or brakes. 3-5 years is typical service life with normal use of the vehicle. It is not possible to register the battery without diagnostic equipment such as ISTA.
If you want to save a little money seek out a reputable independent BMW Specialist near you and ask them for an estimate. Repair shops make next to nothing on tires/batteries/and oil services so don't count on the price for a quality replacement professionally installed to be remarkably less.
