Long-term storage practices for lithium-ion camera batteries during periods of non-use
12 years old. Gear and prices may have changed since.
What the thread found
- Lithium-ion batteries experience irreversible capacity loss when stored in a fully charged state for extended periods.
- Batteries should be stored in a charged condition but not at full capacity, with a partial charge around 40% being preferable.
- Keeping batteries in cool environments during storage helps preserve capacity.
- Batteries stored for more than two weeks enter a deep sleep mode and reactivate when moved, loaded, or placed on a charger.
- Periodically running a discharge and charge cycle during long storage helps maintain battery health.
- Storage duration of one to two months with proper temperature control and partial charge state typically does not cause significant problems.
Depends on
- Guidance comes from device manuals and may not apply to all battery models or manufacturers.
- The exact optimal storage temperature is mentioned as around 10 degrees Celsius but this specific value is not consistently confirmed across all sources cited.
- No direct testing or comparative data is provided to validate the claimed benefits of periodic cycling during storage.
