Test/Review of Keeppower IMR18650 3200mAh (Black) 2014
Keeppower IMR18650 3200mAh (Black) 2014

Official specifications:
  • Nominal voltage: 3.6V
  • Nominal capacity: 3200mAh
  • Min capacity: 3100mAh
  • Max discharge current: 20A

Keeppower%20IMR18650%203200mAh%20(Black)%202014-info

This is a high current battery with very high capacity.

Keeppower%20IMR18650%203200mAh%20(Black)%202014-Capacity

Running this battery at 20A is a bit high, but it does 10A fine and with nearly full capacity.

Conclusion

High current cells has increased significantly in capacity during the last year and this cell is the highest capacity I have seen to date. I cannot match some of the ultra high current cells, but it does very good at 10A (I believe that Keeppower has been a bit optimistic in their marking of the cell).

I will call it a good cell.

It looks like NCR18650BE and it performs better than NCR18650B, NCR18650BD, NCR18650PF.

This is 18650BD right?

A bit better then PF, but yet not sure if the cost of + 10$ is justified….price/performance is not very good on most online stores. Thank you for one more fantastic review!

HKJ, can you tell me what does the second blue line means?

You get the lines for both cells I have tested, here there is some difference between the cells.

It can’t be the NCR18650BE. That cell has a maximum continuous discharge of 3.636A. Since it appears to be good to 10A, it has to be the NCR18650BD (gray wrapper).

Without lamps, there’d be no light.

Have you seen the official specsheet or are you going off by what some random seller or forum posted? Just becomes panasonic rates it at one thing doesn’t mean keeppower can’t rate it for more.

Have you seen any review confirming that NCR18650BE cannot handle higher current? The NCR18650BD positive terminal does not match this keeppower like the NCR18650BE.

18650BE are not high drain, they are lower rated then NCR18650B, which are like 5-6A cellss (max)

What review have you seen that makes that claim? Here is the NCR18650BE performing very well at 5A continuous discharge:

Another thing. Isn’t the BE simply an ICR cell? This Keeppower is specifically listed as an IMR. And although the BD is actually a hybrid rather than a true IMR, hybrids are often sold as IMRs.

Without lamps, there’d be no light.

A mystery cell.
What can it be. ??
Who knows what it is ? Anyone ?

Thanks, because I am on a phone.

Can anyone match this graph to a Panasonic graph ?

Can anyone link the Panasonic Specs
such as ( 20A ). ?
and what panasonic model number is this. ?
-
– is there a protection circuit ??
It says IMR on the label.
Is this IMR, or not IMR ?
If this is a hybrid, what is the correct way to say so ?
Is a hybrid really an IMR. ?
-
I guess I will see how many IMR batteries
that Panasonic makes.
I guess if you think about it,
IMR could mean anything.

i don’t know what that stuff means.
as long as it says made in japan somewhere on there,
i know it’s a good battery
if y’all would not keep testing all these batteries,
we would not be getting so many complaints about them

Do reviewers ever unwrap batteries? Shouldn’t this be a relatively easy question to answer?

If batteries aren't double wrapped, you probably may not find any useful information on the bare steel shell. Or maybe you can.  What does this mean?

The low mode should be lower.

I guess we will never find out the truth about this battery.
Has it been proven there’s a Panasonic inside ??

As you can see in the review I specify it contains a Panasonic cell.

This is because Keeppower has told me that it is a Panasonic cell and I do believe them.

I have not seen a manufacturer lying about the cell yet, they may hold information back, but they do not lie.

Thank you I now trust it is a panny and a good battery , of course.
Does it’s graph match the graph of an IMR battery ?

Try checking out HKJ's website in his signature to compare graphs yourself.  I think you'll be very pleased.

Neither of these batteries in the two links claims to be an
IMR cell. If it is IMR, why dont they say it at FT and BG. Is this battery in the keeppower shrink wrap
really an IMR cell. ? Is a hybrid properly called an IMR ?
I am confused by this label.
I can not be sure this keeppower battery is a BD ,
because no one else calls the BD an IMR.
Is anyone selling this keeppower branded Panasonic ??

LOL. Stop with this nonsense please. They are IMR cells – hybrids.

For this test, has anyone confirmed whether these are NCR18650 BE or NCR18650 BD?

They are of course NCR18650 BD

C’mon man, look at the posts above yours and do some research.

I'm confident that it's not the BE.  Here's a review for the BE.

Here's some of the notable differences:

  • BD is thicker
  • different bottom plates
  • BE has more capacity up to 1A
  • BD has more capacity at 2A and up
  • datasheet for the BE limits current to 3.636A.  

I'd hate to see what would happen at 20A. 

The low mode should be lower.

Whoa, mate, you really need to get that stick out of your arse there.

I did look around and I couldn’t find conclusive evidence myself, thus the question.

But since your post, I went through Fasttech’s website again and compared their BD and BE cells. Their BD cells do look more like the Keeppower cells reviewed here. That leads me to my next question – is there a HKJ review in the works for the NCR18650BE cell?

I’m not very grateful for your foul use of derogatory phrases but I won’t take
offense from someone who themselves is spouting that amount of crap.

You are correct that there is no explicitly explained evidence that identifies the cell.
However, every scrap of information given tells us that this is a panasonic NRC18650BD cell.
