Battery Storage:
The recommended storage temperature for most batteries is 15°C (59°F); the extreme allowable temperature is –40°C to 50°C (–40°C to 122°F) for most chemistries. While lead acid must always be kept at full charge during storage, nickel- and lithium-based chemistries should be stored at around a 40 percent state-of-charge (SoC). This level minimizes age-related capacity loss while keeping the battery in operating condition and allowing self-discharge.
Proper Storage:
- Keep batteries in original packaging when possible.
- Do not store new and used batteries together.
- If a battery feels warm, it should be discarded.
- Ideally, batteries should be stored in a cool, dry place.
- Never store batteries at temperatures over 130 degrees F.
- Remove batteries from equipment if it is not going to be used for 30 days or more.
- Don't let the terminals of stored batteries come in contact with each other.
- Remember-AGA Power batteries have a 3-4 year shelf life!
