We’ve talked before about storing batteries, and how to do it properly. We even showed you a little trick where you can use a Styrofoam cooler to keep the temperature in check.
However, this post is here to give you a more permanent solution to storing your batteries safely.
Temperature
As we’ve said a before, heat and batteries don’t mix. So, storing your batteries in the correct temperature and be everything. It is generally recommended that you keep batteries in a “cool, dry place”, which is generally considered to be 15 degrees Celsius. -40 to 50 degrees Celsius is the extreme allowable temperature.
