The charger said battery's too cold. Temperature has been in the 20s here. I have never had a temp sensor on battery's before and never had any trouble with battery's freezing. Has the charger just out smarted me.
Any thoughts?
The colder a battery is when charging it the higher the voltages that must used for the various charging stages.
Perhaps what the charger was trying to tell you - based on the battery temperature readings that it was getting from the sensor - was that one or more of the proper stage voltages to use on the battery at the temperature it detected were too high (out of range) for what the charger was capable of. There are commonly available charts that show recommended battery charging voltages versus battery temperature.
In other words, perhaps what the charger really "should have told you" was ... "the battery is too cold for the charger to apply the required charging voltage".
