Help thinking of placing a wind turbine.?

I have an unheated garage of the house of my battery bank system for residential wind energy. I worry because here in Michigan to achieve higher temperatures - 30 degrees F. I read that Storage battery banks must be kept near 70 degrees F. Ideas on what I should do?

Lead acid batteries work well at low temperatures. Its current production is very limited, and brownouts, but when heated, yields of capacity. Watch car batteries. You can stay away from extremely cold temperatures, and start the engine, but not both at temperatures higher. If possible, insulate the garage and install a heater with a thermostat is set at 32 º F. Or put the batteries in a sealed insulated with Fire inside, this way is enough to warm the body is not all the garage. Percy has good information. But I would not use sealed lead-acid marine to eliminate the problem of hydrogen gas. And use a charge controller suitable for prevent overloading, which also prevents gas production and extends battery life. .
