Test / Review: Sibeile IMR18650 2800mAh (Black)

Sibeile IMR18650 2800mAh (Black)



Official specifications:

  • Model: 18650 lithium battery
  • Brand: Sibeile lithium battery
  • nominal capacity: 2800mAh
  • nominal voltage: 3.7V
  • battery material: lithium rechargeable battery
  • positive pole: Nipple top

  • Storage Temperature: -5 ~ 35oC
  • Dimension: Diameter 18mm, Height 65mm

The capacity is not that impressive for 2800mAh batteries (this might be because they are 4.3 volt batteries).



After shipping the samples to me, some print was added to the box.








Very nice discharge curve, the two batteries track perfectly and the capacity does not change with load.















Conclusion

The batteries looks good.



Notes and links

The batteries was supplied by Sibeile for review.

So it looks like these actually are IMR?

I doubt it, they look like Sanyo UR18650ZT at 4.2 volt, but newer than the ones I have tested. Try my comparator and compare them, check 0.2A discharge curve. You can also compare the charge curve in the reviews.

Thanks a lot for the review! Frontpage’d and Sticky’d.

thank you for making the effort to insure good quality.
we have questions about the chemistry of these cells.
are you sure that these are IMR cells ??
maybe there was a mistake.
these cells do not behave exactly like other IMR cells.
but otherwise seem like nice batteries, depending on price.

and where is your battery manufacturing factory located ?
can you give us a link to the website for your factory ?
thanks for your consideration.
