Test/review of UltraFire CN18650 9800mAh (Yellow)

UltraFire CN18650 9800mAh (Yellow)

Official specifications:


  • Voltage: 3.7V
  • Capacity: 9800mAh
  • Lifetime: 1000 cycles

UltraFire%20CN18650%209800mAh%20(Yellow)-info
A cheap battery with serious overstated capacity.

UltraFire%20CN18650%209800mAh%20(Yellow)-Capacity
The CELLS can deliver about 1A, at 2A they start to loose voltage and at 5A they cannot really do anything.
The two cells matches fairly well, this probably means the battery is manufactured this way, i.e. it is not a old rewrapped cell.

Conclusion
The cell is as expected, this means low capacity and not able to deliver much current.
The protection specified on the wrapper is not included, this is a bare cell.

Wow ! That’s just blatant misrepresentation. So how do they come up with their numbers ? Do they just put a bunch of numbers in a big tumbler and spin it , then pick one like bingo ?

Thanks for the review!

Tak!!

Unfortunately the people who do not know any better,,,ones NOT on BLF/CPF/The Flashlight forum ect.

Before I found BLF/CPF I started off 7 years ago w/ these kind of batteries when buying flashlights on T mart whose Lumen/Lux numbers were phony on their flashlights also! LOL

Please avoid fully quoting lenghty posts, namely with nested quotes. Trim quotes down to the essential. Helps with neatness and legibility. Thanks.

The human mind, and its programming, is at the forefront of a particular battle of The Light vs evil dark forces. Nearly every human being on this beautiful planet “Earth” has some sort of negative mind programming in its mind. And you better take care of your mind programming, or someone else will in this wicked world.

Now be nice!

It's clearly indicated in writing on the wrap:  "DO NOT knock the battery".

tongue-out

Smile! It makes others wonder what you've been up to.

I really want to put these into my spring-bypassed Q8, in the garden, flick it onto turbo, and see what happens.

But then I like my Q8 so I don’t think I should.

Notable lights: Q8 with 4 x 3V XHP50.2, bypassed springs, brass driver and tailcap screws, Anduril firmware, removed anodisation, AR glass, warm white switch LEDs (16,800lm)  |  Convoy S2+ with triple Luxeon V 4000k, Led4Power B4 Driver, Carclo 10507, bypassed springs (2900lm)  |   D18 in sand  |  D4V2 in sand  |  D4S in grey  |   FW3A with warm white XP-L HI  |   KR4 Mule in blue

Nothing wrong, really. Its unlikely they'll burst, not even if short-circuited. Both their energy and power density are quite low, energy or power cells from a decade ago or more made by the main manufacturers are far superior. Go figure.

You'd have more luck in a shooting range. Wink
