Why should batteries be stored in a fridge?

Storing batteries in a fridge can help prolong their shelf life by slowing down the chemical reactions that occur inside them, particularly for certain types like alkaline and lithium batteries. Cooler temperatures can minimize self-discharge rates, reducing the loss of stored energy. However, it’s essential to ensure batteries are in a sealed, moisture-proof container to prevent condensation, which can cause corrosion and damage. Always allow batteries to reach room temperature before use to avoid potential performance issues.
