[RE-wrenches] Battery at temp

[Hugh]

So maybe we should be heating our batteries up to 
get more energy/capacity out of them :-)  Better 
tell Roy's customer to turn off his AC.

I did read a serious design document that told me 
I should heat battery compartments to 25 degrees 
C in order to maximise performance but I decided 
not to do that in my arrogant way.  I decided I 
knew better how to design an efficient battery 
system than the experts who wrote this particular 
standard.  That was around the time I decided to 
give up adhering to standards and being an 
accredited installer.
