Re: [pvusers] Battery Time



Hello,

This is my first post.  I hope I'm sending to the right address.

I wanted to make sure I understood the State of Charge and Freezing Temperature Chart correctly:

Do I have this right?

* When the temperature is -76 (Fahrenheit) a battery that is 100 % charged will freeze. 

* And at -6 (F) a battery that is 40 % charged will freeze.


At say 0 degrees fahrenheit ( the lowest in my area) at what state of charge would a battery freeze?

Thanks,

Randall

Rough numbers:
State of charge (%) /     Freezing Temp (degrees F)

100 / -76
90 / -69
80 / -62
70 / -27
60 / -17
50 / -11
40 / -6
etc. (do we care?)
