Yeah so that's what I recommend. You can decide if you think I'm overthinking it, but I'd not store the battery in a building connected with the house, I prefer to have it in a place where, worst case, you lose a shed.So the battery should not be stored in the garage? I'll have to find a metal box of some sort - perhaps an old tool box we have in the garage - then store it in the detached shed in the backyard.
