    Storing Lithium Batteries During Winter

    I disconnected the negative side on my Lithium batteries.

    Will they be ok if I left them in the trailer during the winter or should I pull them and bring into the house?

    I don't have lith's but I remove mine and keep them inside. Once a month I put a charge on them. Never have any problems with them.

    From the Battle Born website:

    "The storage temperature range is -10°F to 140°F. We recommend bringing the Battle Born Batteries to a 100% charge and then disconnecting them completely for storage. After six months in storage your batteries will remain 75 – 80% charged. Storing batteries in subzero weather (-15°F or more) has the potential to crack the ABS plastic and more importantly could cause a faster loss of capacity, in some cases drastically more than the typical 2 – 4% per month loss."

    Thanks everyone. I think to be safe I just bring them inside.

    It might be my OCD that lead me to search for this topic here, having already read the Battleborn guidelines for winter storage. Here in southern New England, dead-of-winter lows are generally in the single digits, highs in the 20's - 30's. On occasion we can get a cold stretch down to about zero for a day or two. I've never seen it below -5 (neglecting wind chill) in the 18 years we've been here.

    Yet I too will likely bring the batteries inside out of an abundance of caution. It's not a big deal for me to remove them (and easier to do it now instead of middle of January!).

    Just this year the midwest had record lows reaching -31 F. Safe to say it was too cold for any batteries.

    Not even close to too cold for lead-acid batteries. They can handle down to around -90F.

    You shouldn’t top them off like that. Lithium batteries age faster at full charge or very low charge in storage than they would if being used because of deterioration of the anode and cathode. You want them at a mid-level SOC while not being used for best life.

    Sure, they can "handle" the temperature, they just don't work well. According to Lifewire, lead-acid batteries drop in capacity by about 20 percent in normal to freezing weather, and down to about 50 percent in temperatures that reach about -22 degrees Fahrenheit.

    But that isn’t permanent, and this thread is about winter storage. Cold storage is far better for lead-acid batteries than warm temperatures.
