And I think your memory is failing a bit.
So what temperature was necessary to create a 40% per month self-discharge in a new battery ??
In my memory NO PRODUCTION battery came anywhere near to that figure in temperatures where a human being can exist.
I have no doubt my memory is failing a bit. Thanks for reminding me :B
IEC tests only new production batteries in temperature ranges from -80f to + 150F. most wet cell batteries start falling off at ranges from 1-2% per day in temperatures exceeding 100F, and doubles for each 50 degrees F above 86F. It is not unusual for battery bays or under hood temperatures to exceed 180 F.
At Furnace Creek I recorded 240 F in the battery bay when the ambient was 116F and there are people living there year round.
Don't take my word for it, contact the IEC.
In what part of the battery industry were/are you engaged?
