My Optima battery weighs 34lbs. This Deka battery (EXT14L) is 12lbs. A 22lb loss for $90 or so and 20 minutes of your time.
1) Deka EXT14L $72.xx shipped (from Amazon last February)
2) Purchase battery posts like XS Power p/n: 580 ($10)
3) Trim driver's side front corner of the battery tray to give the battery cables more length
4) Trim the floor of tray to allow the battery to sit down in the little pocket, giving it support front to back and side to side
5) Fill the hole in the tray with something so the battery can partially sit on it. I used a very dense foam. This can be purchased from McMaster Carr.
6) Drill another hole in the tie down strap that will allow a bolt to go through it and be tight over the battery
