According to Trojan, it would need to get below -62F or -52C with a battery charge of 85% for it to freeze. Trojan lists the freezing temperature for a fully charged battery as -92F or -68.9C. I was stationed in Germany. We did not have a problem with the batteries for the vehicles in the motor pool freezing although they would get cold enough that they were not able to crank the Diesel engines. We had to run them to keep them charged enough so that they would be able to start if we had to roll out on short notice.
We did have a voltage regulator in our M577A2 Command Tracked Vehicle go bad. It was boiling our batteries. We had to stop and get out away from the fumes. Then we spent a very cold overnight until the motor pool could get a mechanic out to fix it.
