How to Store a Cell Phone Battery
Storing your cell phone battery correctly can prolong the life of the battery and also make the battery last longer between charges when it is put to use.
Things You'll Need
- Airtight bag or container
Let your battery run down to about 40% charge. Lithium ion batteries are used in the most recent crop of cell phones, and they depreciate quicker when stored at full charge.
Store your battery in an airtight container or bag. This will keep out moisture that may damage or otherwise reduce the life of your battery.
Store your battery in the refrigerator. A cool place provides optimal storage for cell phone batteries.
When you are ready to use your stored battery, leave it outside the refrigerator for an hour before using. Cell phone batteries cannot operate at refrigerated temperatures.
Clean the battery contacts on the battery and on the phone with rubbing alcohol. This permits maximum energy transfer between the battery and your phone.
