batteries in winter storage

But I don't live in 32 below weather, so maybe bringing the battery inside ain't such a bad idea. Although the main thing is to keep a charge on it by charging it once a month or so. That should keep it going through the winter aok. Some people say to not keep the battery on concrete and to put it up on wood. But I'm pretty sure that was an old wive's tale that has been disproven.

Here is an excerpt from a very good battery website that I have found:

"If the temperature is below 0 degrees F (-17.8 degrees C) and you are not using an AC powered engine block and battery warmer or if the vehicle can not be parked in a warmer location, then disconnect the battery, take it indoors, keep it fully charged, and reconnect it just before starting the engine. (Please see the CCA vs. Temperature Diagram in Section 7.2) Alternatively use two 12-volt AGM (Ca/Ca) batteries in parallel and a low viscosity synthetic oil in the engine. Batteries that have less than a 40% State-of-Charge will freeze at 0 degrees F (-17.8 degrees C) and fully discharged batteries will freeze at approximately 20 degrees F (-6.7 degrees C)."

I can provide you the link if you are interested- it is very comprehensive.
