: Thanks to your help I was able to remove the rear seat cushion to get to my battery. By the way what's a good replacement battery? Factory or Die Hard? Thanks again!!! : Actually had mine out yesterday. It's simple. There are only two spring clips that hold the lower seat cushion down. At the center of each seating section, grasp the lower front edge of the cushion. Then pull sharply straight up. This will release the clips. There is one on each side. Once you've done this, you'll have to pull the cushion towards the front of the car to clear the seatbelt receptacles.

For what its worth, an article from the newsletter of the Allegheny Chapter BMW CCA, re-printed in "der Bayerische", (July/Aug 99), National Capital Chapter of BMW CCA; strongly recommended not using a maintenance-free battery. Paraphrased it said, BMWs come with lead-acid batteries, most maintenance-free batteries are lead-calcium. The batteries differ in their characteristics and operation. Differences in charging rates and internal resistance will soon create a condition where the regulator will not fully charge the battery.
