An example is Powerstream
Batteries <http://www.powerstream.com/LLLF.htm> show in their
specifications charge down to -40 C.
I just looked at that, and I read the charge temperature range to be from 0
C to 40 C. Am I reading that wrong. I just checked the CALB (LiFePO4)
specifications I have, and they state charging is allowed from 0 C to 45 C.
Spring can't come soon enough.
You're reading it correctly: 0C to 40C for charge. -10C to 60C for
discharge. It is confusingly written, though.
The CALB CAs are, as you state 0C to 45C for charge, -20C to 55C for
discharge.That extra -20C is why I chose to only heat my batteries when
the truck is plugged in. I'm not particularly concerned about them
getting cold during the day while I'm parked at work.
