Battery cost?

$45.00 - 150.00 try and put a gel battery in it.A modern gel battery (also known as a "gel cell") is a VRLA battery with a gelified electrolyte; the sulfuric acid is mixed with fumed silica, which makes the resulting mass gel-like and immobile. Unlike a flooded wet-cell lead-acid battery, these batteries do not need to be kept upright.

If you don’t have a battery programming tool, is to take it to the dealer for the replacement. From various posts, the cost averages about $500, which is $250 for the OEM BMW battery and $250 for the installation and programming. Some say the programming alone can be as low as $100 if you do the rest yourself, but dealers seldom let you leave with a bill of only $100.
