Winterizing lithium batteries
How do I winterize my lithium batteries or do I have to. The temperature is starting to drop at night. I read if fully charged they only lose 3% per month.

Steve thanks but would the core freeze if they are left outside?
no they dont get hurt from storing them even fopr up to a month at -45C and up to a year to -35C. the numbers posted above are for usage at different temps, the battery must be above 0C to charge it and above -20C to discharge it.
if you get below -35C then I would thing about disconection it and brining it inside the house.
Once again PianoTuna is quoting numbers from older Li chemistry.. as long as it is not at 100% you will be fine, thats why I say discharge it to 90% and let the natural loss take it down while in storage. I even wonder what starting at 100% would do in all reality... even new smaller Li batteries that are shipped in stuff are normaly at 75-80% when you buy them now, not like 20 years ago when you bought a new cell phone and had to charge it over night before you used it.
