Interesting...was working out in the garage yesterday with the door open. It is like 30 deg out.... after about 1 hour my BP would not fire. Brought it inside and all was good. The batteries ran for another 4 hours before needing to be charged, so they had a good charge on them.
So it seems Cold does something (either to the contacts or to the batteries..).
