Test/Review of TrustFire 14500 900mAh (Blue) LC

[size=+3]TrustFire 14500 900mAh (Blue) LC[/size]



Official specifications:

• Shell material: steel
• Rated voltage: 3.7V
• Internal resistance: <= 100 milli ohm
• Low voltage cut off: 2.75V
• Over charge voltage cut off: 4.2V
• Maximum charge current: 1.5C
• Maximum discharge current: 1.5C
• Diameter: 14.0 +/- 0.5mm
• Height: 51.5 +/- 0.5mm
• Environmental temperature (operating): 0~45'C
• Environmental temperature (charging): -20~60'C

As expected the capacity is lower than rated.











The batteries can easily handle a 1A load, but due to capacity differences they are not suited for usage in series.















[size=+3]Conclusion[/size]

These batteries has better performance, than last time I tested them, but I will still rate them as acceptable for a cheap battery.

Battery was supplied from LightCastle for review.

I have tested this battery before, but with a different result.

Thanks a lot for your time & effort. Your excellent review is very helpful & informative. :thumbsup:

Trustfire = Ultrafire?

I ordered several of these to run in some pocket AA/14500 Cree flashlights...would like to know if the above applies to them as well
