After 13yrs of owning my car the battery finally died.so i decided to go from the flooded battery it came with and go with a AGM battery,Theres a guy on youtube "VehicleDIY" did a video on upgrading but my issue is that battery(Interstate H8(49)agm 1355853) cant find it online to buy from interstate.i did find InterstateMTX-49/H8 but not sure if this would fit.the battery that came with my car is
Battery Markings:
BMW
61 21 7 575 572
746075 720 Amps
Guess what im looking for what other e90 335 2006-2008(not sure if 2009 & newer applies here) owners if they have done the AGM upgrade and what Brand was used. I know Interstate is a good name brand and was sliding that way.looking for some feedback,thanks.
