How should I store my batteries? Would keeping them in the fridge give them a better performance?

We recommend storing your batteries in a dry place at room temperature. It isn’t necessary to refrigerate your batteries. Be aware that cold temperatures can cause the chemical process powering the battery to slow down. Therefore the device won’t necessarily run at full performance rate (for example: your flashlight may not shine as bright as usual). Avoid also high temperatures as that will degrade the battery.
