At the moment, there are no third party EN-EL25 batteries available. However, third-party chargers for the EN-EL25 do exist:
- Kastar EN-EL25 AC dual battery charger
- Kaster EN-EL25 USB dual battery charger
- Kaster EN-EL25 AC single battery charger
Also, Tether Tools now has a “dummy” battery (CRN5B-C) for connection to their Case Relay Power System, which allows you to continuously power the camera for a longer time. Tether Tools backed off from producing this.
