10180 batteries test

Batteries and Chargers Rechargeable Batteries

A few weeks ago i received a Klarus Mini One while not remembering ordering one and not even knowing anything about that flashlight... after a few embarrassing moments i eventually found that GB had mistakenly sent me this one instead of an other flashlight.

While the light looked nice and the price was about the same i decided to keep it and ordered again the other one. After some tests i liked it so much that it became my pocket edc light and i ordered a second one plus some spare 10180 from ebay so here are the test results of the 10180 batteries i have :

What :

  • 2 Klarus LiR10180 3.7V 0.26Wh (so that's 70mAh) that came with the two Mini One
  • 2 unbranded, unmarked blue 10180 from ebay (this seller but many others sell what seem to be the same batteries)

How :

  • SkyRC MC3000 charger/discharger
  • Before each discharge test the batteries were charged @50mA, 4.20V with a 10mA end current (lowest possible on the MC3000)
  • Discharge end voltage was set to 2.80V
  • While the 10180 batteries are shorter than the minimum size, homemade extender covered with copper foil were used
  • DC resistance is the value given by the MC3000 averaged from several measures

Test results :

K1 K2 EB1 EB2
DC resistance 670 mΩ 680 mΩ 510 mΩ 580 mΩ
50mA discharge 67 mAh 52 mAh 74mAh 74mAh
100mA discharge 64 mAh 48 mAh 71mAh 71mAh
200mA discharge 56 mAh 33 mAh 64 mAh 60 mAh

Very disapointing result for the second Klarus while the ebay ones are surprisingly ok and even more knowing that they are less than 1/4th of the Klarus price

Thanks :+1:

Nice. I’ll have to get some. I was needing some more 10180, but was hesitant to try unbranded/untested cells. Especially on eBay, there have been lots of fakes.

Well, I didn’t buy from your vendor, but you were right. There are plenty of listings that look like the same product. I hope it’s true. I paid a little less by going with a different vendor. :money_mouth_face:

For fakes to exist there must be something worth being faked. ;-)

Cheers ^:)

Yeah, I thought about that. The 10180 isn’t exactly a very popular size. Sales would be limited mostly to people like us. Then again, there are plenty of fakes in other sizes, so how hard could it be to add a smaller size to the line-up in a Chinese factory that’s pumping out fakes already?

Thanks for the test!

Nice info, thanks for testing!

Received two of these 10180 cells today, 70mAh at 200mA discharge rate and 61mAh at 300mA, 440mΩ IR :+1:
