Warning - use of non-OEM batteries
Oct 28, 2022 09:01:56 #
I had the same warning message appear when using “BM” batteries in my R5. I put them on a shelf and didn’t use them for a few months. One day I decided to try them again and so far everything seems to work fine. However in looking at the specs on the BM batteries and and “Powerextra” off-brands, I notice a voltage variance. Canon LP-E6NH batteries show 7.2 volts. The off-brand batteries show 7.4 volts. The .2 volt difference could possibly cause issues, but I’m still using them without any more warnings or problems.

Hopefully the battery power goes into a voltage regulator circuit where the extra .2V would not be a problem.
(The camera may actually run on 6V.)

the .2 volt isn't a problem besides if you measure the voltage they may not be what they said.

I have been using 3rd party batts in my Sony A7R series cams for years, even professionally in a series of documentaries in extreme conditions in the Arctic. Still working fine at full capacity, as good as OEM.

The ‘smaller’ battery - used in my small-sensored Pentax MILC - shared with Fuji and Kodak - is 3.7 volt. The ‘regular’ battery used by some K-mount cameras is 7.4 volt. Perhaps this is just a case of Canon’s being different because they can be. What is the standard Nikon battery??

Most of them are 2 cells 7.2V.
3.7V is one cell.

"Standard" can change as technology changes. It depends on what on voltage the circuitry for a particular camera uses.

A lithium ion battery cell voltage is about 4.2V when fully charged. It would drop down quickly to about 4V and then down to 3.7V for most of the remaining useful charge. So the manufacturer of a 2 cell battery pack can rate it anywhere between 7.2 to 8.4V because that's how much the voltage changes when you use it from full charged to empty.

I only use OEM batteries. My thought is, if something were to happen to the battery and that damaged the camera, big expense. So you have noted. Why gamble?

I couldn’t agree more. Just not worth the risk.

WARNING: A cheap (or expensive OEM) lithium battery case can warp if it overheats in your camera and then it can be difficult (if not impossible) to remove from your camera. I have seen this happen. If a battery does not easily slide in or out of your camera's battery compartment, stop using it! Of course, if a cheap (or expensive OEM) lithium ion battery catches fire in your camera, that is the end of the camera! That is why the FAA does not allow lithium ion batteries in the checked luggage hold of aircraft.

So Pentax has their voltage regulator set a tad higher than Canon and Nikon do.

Exactly. It wouldn't surprise me of Canon puts a chip in their batteries so they are alerted when you're using a knock-off. Much like printers. Once you do a firmware update they learn the camera is not using their equipment and shut things down. Epson printers are famous for this sort of behavior.

Too bad some of the best tested batteries seem not to be available in the US.
