If it’s not a bad batch of batteries, what can kill a battery in a parked vehicle?

Did you make sure to get the battery to a full charge (ie: trickle charger or a drive to Canmore and back) before letting it sit idle?
If it wasn't fully charged, then the fact it can drop too low can be a problem, even if it is new. It's also possible that it's a culmination of factors. Maybe slightly incorrect storage from Canadian tire (if original and replacements were from same store/batch) and perhaps some issue with the same batch (so replacements are still subject to the same issue)?
