Battery and cold weather?
Posted: Mon Dec 22, 2008 8:27 am
Does cold weather (0 - 10 degrees) affect battery performance? 
YES it does. Some batteries worse than others. Lithium batteries work the best in the cold - but once its below 20 or so - the battery chemistry will start to slow down - and has the chance of freezing.
Other battery types go out much sooner.
You can end up with a reduction of 60-90% of capacity - or more...
