What I Check Before Buying

I store them in a cool, dry place so they stay ready when I need them.
Performance in Everyday Devices
From my experience, the best battery is the one that works consistently in the devices I use most. A Rayovac 9 volt battery is usually a practical pick for low to moderate drain devices.
