.?? I’ve dried bats this way for 30yrs , never had a bat break yet
I’m not recommending doing it, but being left in a car or van has the same effect etc. My airing cupboard is 30c,,,my van in summer can be over 40c,,,my car has seen well over 40c if parked in the sun
I’d say this is the one area batmakers are trying new methods, to compete with the Aussie gn bats for instance
Buying public want the big light bats
I’m not talking David Warner style 5percent moisture, just getting as much out as possible
My experience is the bats have a standard moisture once they’ve been dried out, then this can vary a couple of ounces each way depending on storage conditions.
