Learn how to use the Canon CG-800 Charger with compatible batteries, plus how to set up continuous power with a SmallRig D-Tap to LP-E6NH dummy battery cable for long shoots.
Quick answer
The Canon CG-800 Charger works with LP-E6NH batteries and can be paired with a SmallRig D-Tap dummy battery cable for continuous power during long shoots.
Why a dedicated charger matters
Using the Canon CG-800 Charger ensures your LP-E6NH batteries charge safely and at the correct rate. Third-party chargers may not support full battery decoding, which can cause error messages or incomplete charges.
If you shoot video or time-lapse, a dummy battery setup like the SmallRig D-Tap cable lets you run your camera from a V-mount or gold-mount battery, avoiding mid-shoot swaps.
How to use the Canon CG-800 Charger and set up continuous power
- Charge your LP-E6NH battery: Insert the battery into the Canon CG-800 Charger until it clicks. Plug the charger into a wall outlet. A red LED indicates charging; green means full. Do not force the battery in backward—it only fits one way. Remove the battery once the LED turns green to avoid overcharging.
- Connect the SmallRig dummy battery cable: Insert the LP-E6NH-shaped end of the SmallRig D-Tap cable into your camera's battery compartment. Route the cable through the provided slot or channel so the compartment door can close without pinching the wire. If the door won't close, check that the cable is seated in the dedicated groove—never force the door shut.
- Power from an external battery: Connect the D-Tap end of the cable to a compatible battery pack (e.g., V-mount or gold-mount battery with a D-Tap port). Turn on the external battery, then power on your camera. The camera will recognize the dummy battery as a genuine LP-E6NH with no pop-up warnings. Always disconnect the dummy cable from the camera before removing the external battery to avoid voltage spikes.
