Got a new charger-Miboxer C4-12, 4 slot X 3A/slot, total 12A output

I used to be getting IR of 60-85 IR but now its way higher

559

No, do you even have a new wrapper to put back on it?
It’s possible the original wrapper might have been removed anyway to keep it from getting too fat in diameter.

When I say “the cell under the wrapper” I don’t mean to cut off the current wrapper and look. You typically have to do some online research or maybe ask Sofirn. Surely somebody on BLF knows.

560

I think your worrying over nothing. What light do you use it in? Is it noticably dimmer?

Maybe you should stop using your C4-12 to measure IR. Surely there is a better way to measure it.

561

Yes I do have a wrapper to put back on it. When i was reading Dales review of the Sofirn C8F updated version, he said it was a 30Q (dont quote me on that though).
I took the wrapper off and it just says “ISR18650”

Here is a picture also… Pink in color

562

Im not using the charger to measure the IR. It is just there for me to always see. My charger is working great with my cells. I am just trying to learn more but if im annoying you guys i will stop.

563

Dale says it’s not a 30Q, but still performs really well. Here is his post.

I can see it needs a wrapper to help hold the white disc on.

564

I seen that also about the disk. Its been a few weeks since I read his post about the cell, so thats my mistake. Sorry. It does perform great! I was surprised.

Thanks Jason, everyone and sorry for all the trouble. You were very helpful

Charger or battery…
…….Scotch Brite Blue or a clean rag & call it a day.
Add a tiny bit of alcohol if needed. No real need to overthink this unless your batteries or charger get much, much more dirty than mine…… :wink:

Thanks

Geez, that’s complicated. It’s no wonder the charger has a difficult time trying to measure it accurately.

I’ll have to read the full length of it later.

568

Here is HKJ’s review of a really easy to use IR tester.

569

I do tend to over think things sometimes. Sorry and thanks. I guess it’s just the way i am.

570

I second that. My C2 6000 measures every cell I have over 100 mohms . All new cells from good source.

571

Cool device, but it looks like $65 minimum price with battery holder. I don’t think I need to know exact IR that badly. Lol. Maybe in the future.

572

No need to apologize, I know how it is. I can be the same way… it takes one to recognize one you know. :smiley:

I’m still trying to learn not to sweat the small stuff in many cases…. :smiley: :smiley: :smiley:
The struggle is real……… :wink:

573

Thats another thing teacher…. I say “sorry” a lot! It is definitely a struggle when you dont know why you’re apologizing.
Good to know I’m not the only one though

574

:+1: … :beer:

575

Yeah, the price is enough to keep one from getting OCD about it. :laughing:

576

I got a bit annoyed having to wiggle my blue Liitokala’s so I fixed it with an xacto knife.

Problem solved. Lol

My black Liitokala’s don’t have this issue.

It looks like there is a new 26650 Liitokala in blue, it’s got a different label, is rated for 5100mah and has slightly extended ends which make contact end to end with no solder blob needed. Just thought I’d mention it. Bye.

577

Actually, I have the same problem on both the C4-12 and the MC3000 (on my MC3000, the negative poles/post leans backwards a lot, and I need to adjust the 26650 for it to make proper connection… this is for the cyan INR26650-50A…)
