OH NO! Did you cut your battery?
I made a small slice in the bottom of mine but did not cut all the way through. I was surgically removing bits of that honey cone mess where the bracket goes. Using a die grinder with a cut off wheel in it. Something looked and sounded funny. Plastic looked shinier and felt kind of slicker.
Good thing is my wife keeps asking me when I am going to get a new battery. We have both read posts about these batteries going belly up after 2-3 years.
Good God have batteries gotten expensive. Got my eye on that newer Odyssey.
Someone really should put out the warning/ word that you need to remove the battery before starting this project.
