Do putting batteries and perfume in the refrigerator really extend their life?
In short, storing batteries in a refrigerator might add a few more minutes to their shelf life, not enough to justify the additional time they’ll need to return to usefulness. It is far more important that you store your unused batteries away from heat sources and areas prone to high humidity. Heat and humidity will cause stored batteries to leak fluid, and prolonged storage in a device may also encourage corrosion and leakage.
