I put this battery in my 1996 Mazda Miata. which has a rear battery in the trunk and a 1.8l up front. The what I think are M4 hardware used for terminals is small for my application but its something I had to deal with when I put a tiny battery in my car. I autocross the car so the battery needs to be heald down. The battery, box, and strap, and a the wiring to hook it up to stock car termimals weighed in at 6.2 pounds. the battery I took out with mounting was 40.4 pounds. So well worth it. car has sat for 4-5 days without starting and starts fine. also has started and turned off 6 times within an hour with the autocross runs.2 scary parts. when you see the battery its TINY. it does not look like it would start a car. I hooked it up right out of the box and fired right up. Also every now and again. im starting to narrow it down to after a short drive followed by a short sit. like going to a restaurant and having dinner. I feel like it barely starts. you get a slow crank that gets faster and faster and then it starts. It has always started. all in all its a great battery and Odyssey's sticker has earned a spot on my roll bar with flyin miata and boss frog racing.
