Hey fellow corner carvers,
Just wanted to share my experience as I don't see much talk of lightweight batteries around here. Thanks to this thread I decided to finally get around to installing my old Deka ETX9 7lb battery from my old Miata, which had been sitting in my basement on a trickle charger for a year. My car is a daily driver, so for now I've got my stock battery sitting in the trunk just in case. No permanent modifications needed other than a little trimming of the battery tray and drilling a hole in the nylon battery strap. If it dies I can swap my OEM battery back in with an 8mm ratchet in about 5 minutes.

From @s8v4o 's thread:
Hump that needs trimmed
After about 5 minutes of Dremel work
Stick something in the gap to make a flat "floor" for the new battery
Drill an extra hole in the strap
Test fit
All set
On mine I had to trim out the corner of the tray near the positive side of the battery because the ETX9 is very short and the wiring leading to my positive terminal was extremely stiff and did not want to bend down. However if you go with a taller battery like an Odyssey PC680 or Deka ETX15 you shouldn't have to do this.
