I inserted a pair of 18650b’s equally drained to 3.6 v.
In one slot, the battery is charging ok, while in the other the charging stopped at 3.72v, showing 3 solid LEDs.
Sometimes it mistakes a Ni-MH cell for a Li-ion and overheats it pretty much, so I have to keep an eye on it - if the third LED does not start flashing after several hours - I pull the battery out and measure the voltage with а DMM.
Thanks for the info.
Now it worked, tried it a couple of days when I tried before.
I did post to there support about it earlier also, probably like many others
And it was nice to know get/confirmed it was a legit charger.
I have the same thing regarding the magnetic parts on my D4, only the positive is non-magentic, negative and the rails are magnetic and the validation check says:
"Invalid request! Registration unsuccessful.
This product with serial number of 8462548401078217 had been registered for warranty service on (03-01-2015 11:30) . If the first verification attempt wasn't carried out by you, please contact your seller before taking further action."
I googled my code and got a few hits including this:
"Finally, after validating the scratch code 8462 5484 0107 8217 on our validation page(http://charger.nitecore.com/validation), it showed that the first-time validation happened in last year and not operated by our sales! That means it is a counterfeit charger!!!"
"In this case, we think many counterfeit chagers are using this fake validation code( 8462 5484 0107 8217)!"
I see there is also an earlier post with someone who also got a charger with the same validation code
Thanks, I had a good look around Google wasn't anything concrete apart from the charge rate, that link seems to imply that just below 1.6v is a suitable termination voltage?
I charged my Duracell AA's on my new fake D4 and the cells didn't get overly warm, the termination voltage was just around 1.56v, the charging has finished and the 4 cells are now at 1.5/1.5/1.51/1.5v
Hmmm, fill the fake electronics with banned substances, ship them across national borders, carefully vacuum them out, sell the white powder one place and the fake electronics on eBay …. a business plan? Nah, that would be too much trouble.
