The battery for a 450sl, post 1974, should be found in the trunk. Inside the trunk compartment, on the right side inner wall, you'll find a little black knob at the top of the paneling. Turn the knob to the left and pull the panel down (its on a hinge). You'll find a square plastic box with two metal hinge straps. Unlatch those straps, lift the lid of the black plastic box, and voila!....you've found a rather large 12 volt battery. BTW, to the right of the battery casing, you should find your tire jack and tools in a compartment. Suggestion: If you're planning on replacing your battery, make sure you get a good one. Remember, you're dealing with a 70 watt system, and a cheap smaller battery won't work properly...these cars are electrical pigs...they're powering a lot of stuff. I've always used SEARS DIE HARD batteries....they're just a few dollars more, and worth every penny. You should be aware that car batteries usually last 3 to 4 years...5 years tops, otherwise you're taking a chance ...and that goes double if you live in a climate with snow or exceptionally cold areas.
