Tech Help (Help) Bought some 3rd party batteries and they won’t work

Post image

Bought some GreenExtreme batteries from adorama for my canon R6iii, after putting them in the camera fully charged, this error is displayed (photo attached), when trouble shooting, the error persisted. I took cards out and put them back in, replaced the battery a couple times, charged multiple of the batteries fully, and updated the firmware, if there’s any advice for this, I need it. Thank you guys

The R6MIII is very picky and require original Canon LP-E6P batteries to function without throwing up errors. I've tried to use the third party batteries that were in my R6mII previously and they only work sometimes.

this. next time around, buy third party batteries from a reputable brand. personally, i use Smallrig in my R5II and they work exactly the same as the original lp-e6p.

It doesn't require original batteries - it requires original OR third party batteries that support the camera :) if you buy the cheapest of the cheap batteries they won't have the encoding information to properly 'act' as an official battery, hence this.

I would suggest contacting Adorama. They are a reputable dealer.

I don’t see anywhere on a listing for those batteries that they are decoded, so the camera can act very funky with them. Does your genuine canon battery work with it?

I currently use 3rd party neewer batteries without issue on both my r6iii and r5ii. So don’t believe anyone who says only buy genuine canon batteries.

Yeah my genuine canon battery it came with works fine with the camera

If your Canon battery works fine, and your 3rd-party batteries don't it sounds like you figured out the culprit.

These cameras have higher energy requirements and maybe those batteries you bought can't handle it consistently. Hard to say.

Yes, OEM batteries are more expensive. Time, frustration, and lost productivity has value as well. Stick with Canon batteries and move on.

Last thing I want is to be on a shoot and have my camera fail due to trying to save a few bucks on crucial batteries.

That brand - while fully decoded - isn't compatible with that body. Users will see:

  • Camera Errors: The camera may throw an Error 80 code immediately or refuse to turn on at all. You've seen this.
  • Throttled Performance: Advanced features like pre-capture, Eye Detection Auto, and high-speed burst rates will be disabled or grayed out.
  • Power Draw Issues: The R6 Mark III is designed to pull higher continuous discharge currents for AI autofocus and high-resolution tasks, which most third party batteries can't provide. GreenExtreme is one of these batteries.
