This video makes it pretty clear, even in German. No need to remove anything other than the front service cover (hood).

Update. It appears that the video from Germany above is a Smart car without A/C ducting. Looking down at the battery, you can barely see 1/3rd of it on my car compared to the full battery of the video. Only 5 inches, so no other choice. I plan on trying to remove the ducting using the Torq screws it looks like.

OK. I have replaced my 2017 Gas Smart Car Battery. It completely died after midnight when it set off the alarm and would not shutoff. I finally got it stop, but could not lock the doors electronically. Anyway...
OEM = Fiamm 12V - L2 EFB 60Ah 510 (EN)
Per the internet you can use an AGM battery (as an upgrade to the EFB battery.)
New Battery = Duracell Platinum AGM Size 47 (H5) - At Autozone and others. I got mine at Sams Club.
Here is what you have to do. (see pictures below)
01. Remove the front hood.

02. Pull the weather seal strip off the edge. Mine had sticky tact, but not glue on it. (Right Green circle above)
Stop when you get to the right green circle area where the vent cover has a split
03. Use 2 different sized Torx screw drivers and remove the Torx screws in the red circles.
04. Slide and remove the form insert at the end of grill area (yellow circle above on the left).
05. Using a flat blade screw driver pop and pliars to remove the 2 push snap plastic connectors in the left green circles.
06. At the top of the right red circle there is a small slot above the Torx screw hole. Use the flat screw driver and slide it into this slot to the left. This popped the plastic grill off and able to remove the top piece.

07. Using a Size 10 Metric wrench with an 5 inch extension, unscrew the 2 bolts in yellow circles above.
They are over 2 inches long.
08. In the blue circle above, there is a foam rubber tube with split finger ends that will slide out when you remove the bottom part of this grill.
09. The bottom part of the grill can now be pulled toward you. It has some guidepoints on the bottom to align it when you put it back. Move this to the side.
10. The battery is now exposed to remove it.
11. The negative terminal above uses a #10 size metric that you can barely reach it under the electric wire, but you can take it off and move it to the side.
12. Remove the red cover over the positive terminal

13. remove the 2 nuts on the top of the positive terminal above (yellow circle)
14. I would cover the positive terminal harness with tape since it is hard to keep it from falling over.
15. In the red circle is a LARGE Torx screw bolt clamping the battery down to the base of the battery holder.
16. My largest Torx was too small. I had to use a large 15 inch long flat blade screw driver to get this out.
17. The battery is now able to be removed.
18. Remove the mounting bracket from the top of the old battery positive terminal with a #10 metric.
19. Take the mounting bracket in step 18 and put it on the new battery positive terminal.
20. Next, I took the clamp from step 15 and put it in BEFORE the battery. I only turned it a few turns.
21. Place the new battery in leaning/slanting it toward you so the lip of battery goes under the clamp.
22. Tighten down the clamp for the battery base.
23. I removed the tape from the positive terminal harness and reconnected the nuts from step 13.
24. return the red rubber cover to the positive terminal.
25. Re-connect the negative terminal with the #10 Metric
26. I tested the battery at this point. Car started up fine. lock/unlock.
Reverse the steps to close out the replacement.
27. Bottom part of grill - Reverse actions on Steps 9, 8, 7
28. Top part of grill - Reverse actions on Steps 5 - be careful, do not use a hammer. very close to glass on 1
29. Reverse actions on Steps 4, 3, 2, 1 - YOUR DONE!

Kevin, I notice that you have the same battery, p/n 453-982-02-00, on your 2017 ICE smart as I do on my 2017 ED smart.
I have found out by calling and email communication with Connecticut Mercedes-Benz of Fairfield, that the online catalog links are in error, and the ICE engine should take the p/n 453-982-00-08 battery, which is a bit less expensive.
You can confirm the correct battery by calling and asking your M/B parts counter guy the correct part for your car. Once you have the correct battery, it may be cheaper to order the part online than from the parts counter at the dealership.
The email to me stated "Will note this error. The online catalog is managed by an outside source with pulls data from our system. How often they update it against our own catalog I am not sure of. But it will definitely be noted. Thank you."
And thanks for posting how to remove the battery. I had given up when I noticed to that the battery couldn't simply be lifted out, but your instructions have given me hope.
Moderators: Maybe the sticky can be linked to the ED section of the forum too, so other 453 ED owners can find it?
