So I recently bought a 2012 Leaf with a degraded battery and am in the process of upgrading it to a 40 kWh battery that I bought as part of a donor car.
An issue I'm having is that at some point, the previous owner of the donor car jacked up the car and missed the jack point, lifting the car by the battery pack. Or maybe some forks got it at the yard. Either way, there is a seam between two pieces of metal on the underside of the battery pack and that seam is caulked at the factory. A three inch section of the bead is no longer sealing the case, and there's maybe a 1mm or 2mm gap letting air into the battery pack.
Any idea what would be a best practice to reseal the battery pack?
Also, I found a previous post by Dala on pressure testing a pack. See:

I had an idea I wanted to share on pressure testing a pack. My cpap machine is capable of accurately maintaining a pressure of 0.23 psi (approximately 17 cm of water column), so I was thinking of hooking my cpap machine up to the 'new' battery pack with some vinal tubing, a barb fitting, a check valve, and a manometer tapped in between the check valve and the battery pack. Thoughts?
