Test/Review of UltraFire XSL18350 1200mAh (Orange)

[size=+3]UltraFire XSL18350 1200mAh (Orange)[/size]

I got this battery from two sources with a few months between.

[size=+2]Sample from LightCastle[/size]



Official specifications:

• Rechargeable Yes
• Lithium Ion XSL 18350 cylindrical rechargeable batteries
• Typical Capacity: 1200mAh

As usual with cheap batteries, the capacity is considerable lower than specified.










As long as the battery is keep at low currents it works fine, but drawing 2A or more the batteries looses capacity and they do not track.

Official specifications:

• Lithium Ion XSL 18350 cylindrical rechargeable batteries
• Typical Capacity: 1200mAh

Again the capacity is lower than specied.










These cells has less capacity, than the first batch, this may be due to age (Note: I did test them in December).
They have the same problem with currents above 2A as the above cells.















[size=+3]Conclusion[/size]

These batteries are acceptable for cheap batteries.

One of the sets was supplied from LightCastle for review.

Interesting, I've had a couple of these for quite a while and have been happy with there performance.

As usual HKJ your tests are greatly appreciated.

Thanks Norm

I've been hoping you would test these and confirm what I suspected. Thanks! You saved me the trouble of buying/testing them myself. :thumbsup:

For any of you reading this test wondering "what is the best 18350 for higher drain applications?", AW's 18350 is a fine cell. I have used and tested several of them quite a bit. :thumbsup:

Another excellent test review! Thanks a lot for your effort & time as always. HKJ! :thumbsup:
