Could someone help I bought the BMW battery charger last year not really used it properly so just want to make sure I'm using it right, brand new battery maybe two years ago but with the car not being used I need to get this charger on and bring the battery back to life
. Can someone tell me if I put the setting onto normal or lithium iron? Its the correct battery from BMW and I haven't a clue which it is. Sorry for the really stupid question.
