Storage and maintenance of nickel-cadmium camera batteries
19 years old. Gear and prices may have changed since.
What the thread found
- Nickel-cadmium batteries self-discharge over time during storage and should be recharged before use
- For storage periods exceeding six months, fully charged nickel-cadmium batteries should be placed in a sealed plastic bag and kept at approximately 8 degrees Celsius to minimize discharge
- Batteries that have discharged beyond recovery point may sometimes be recovered by repeatedly placing them on and removing them from a charger until the charger begins charging again
- Some charger models are more effective at recovering deeply discharged batteries than others, particularly simpler designs without intelligent circuitry
Depends on
- Storage recommendation applies specifically to nickel-cadmium types, not other battery chemistries
- The recovery procedure for deeply discharged batteries is time-consuming and success is not guaranteed
- Recelling costs approximately 120 currency units per battery unit
- One user experienced failure of previous generation batteries regardless of storage method
