Quick Answer

A battery grip that won't charge usually has dirty contacts, a faulty power source, or a grip-specific charging path. Start by cleaning the metal pins and testing the battery in the camera body.

Why the Grip Itself Doesn't Charge Batteries

Most camera battery grips do not contain a built-in charger. They are designed to hold batteries and pass power to the camera. If your grip isn't powering the camera, the issue is often a poor electrical connection between the grip and the camera body, or between the grip and the battery.

The Nikon MB-N11 and Canon BG-E22 both rely on clean contact points. Dust, oxidation, or a slightly misaligned battery can stop the circuit. Always check the metal pins on the grip and the corresponding contacts inside the camera body first.

Common Misconception: Charging Through the Grip

Some users assume they can plug a charger into the grip's DC-in port. This is not how most grips work. The grip's external power port is for connecting an AC adapter or external battery pack, not for charging internal batteries. If you plug a charger into that port, nothing will happen.

For both the Nikon MB-N11 and Canon BG-E22, you must remove the batteries and charge them in the dedicated charger that came with your camera. The grip only provides power to the camera body.

Diagnosis Steps

  • Symptom: The camera powers on from the internal battery but not from the grip, or the grip's battery indicator shows no charge even after inserting freshly charged batteries.
  • Likely Cause: Dirty or oxidized contact pins on the grip or camera body. Also, a dead battery in the grip that the camera's charging circuit cannot detect. Check that the batteries you insert are fully charged in the dedicated charger first.
  • Corrective Action: Remove the grip. Clean the metal pins on both the grip and the camera body with a dry microfiber cloth or a pencil eraser (gently). Reattach firmly. Insert known-good batteries. If the grip still does not power the camera, test the batteries directly in the camera body to rule out a battery issue. If the camera works with batteries inserted directly but not through the grip, the grip's internal circuitry or contact block may be damaged.
  • Stop or Choose Another Option: If cleaning and testing do not restore function, the grip likely has a hardware fault. At this point, consider replacing the grip. Both the Nikon MB-N11 and Canon BG-E22 are available with a 1-year warranty and free UK delivery. Do not attempt to disassemble the grip yourself — it can void the warranty and damage the electronics.
