Wow..7200 mAh 26650 batteries

Whoaa… for 26650 batteries, it’s up to 7200mAh now? :bigsmile:
7200 mAh 26650 batteries

Another Ultrafire with a different color scheme…7200mAh…hmmmm

This made me think of a note I got from a friend this morning.

He tells me he just bought 2 of these 7600lm Bike Lights for $62.00 each from eBay that he going to use for driving lights.

I point out to him that Fasttech has the same light $7.00 less, and call it a 4000lm light.

I also question the usefullness and value of the apparently sealed battery pack.

I advised him that when he gets the lights he should leave the seller negative feedback and tell him if he revises his lumen estimate to 4000 and refunds $7.00 per light he’ll change the feedback to positive.

I forget the official specs, Ultrafire is divide by 3 for capacity, and roll a 1 on a 20 sided die for explosion?

Yeah, Ultrafire make good to great lights (I love this C1 I have). The only __Fire-brand batteries that are any good are Trustfire flames. Otherwise, stick to AW/Panasonic/Sanyo/Samsung.

Unless HKJ says otherwise.

You forgot to do the math,

7200mah / 6 = 1200mah each :bigsmile:

+1 :smiley:

±300 mAh per cell. More - than +.

Rechargeable battery pack? That’s a good one!

Is this one the protected type?
I see it says “Rechargeable battery with PCB”, this means the protected, right?

Sure, if you are lucky the protection actually works…seriously…Ultrafire batteries are very poor quality typically. I wasnt joking with the 1/3 capacity probability, 1/6 that others posted is even possible. I had some 1/2, 1/3 and 1/10th capacity. The ones with 1/2 and 1/3 capacity started to degrade after only a few charges…then I researched more and never bought Ultrafire batteries again.

i noticed there is no PCB on the bottoms of these super-cells that claim to be protected. :Sp

Similar situation recently, resulted in 3 doa batteries, 1 dud after single use, and 1 that worked but was ultimately trashed when I was informed how vastly unreliable Ultrafires are.

I would stick to tried and true brands; I’ve got some nitecores and panasonics that have yet to disappoint (nitecores going on about 3 yrs old, panasonics are new with heavy use over the last ~month).

The negative credits do not all go to Ultrafire. When bought on ebay, you can expect dubious batteries from waste electrical equipment rewrapped with Ultrafire wrappers (you can buy the wrappers also, usually with 'Ultrafire' on them, even Fasttech had them for a brief moment). Although Ultrafire probably does not make very good batteries, this has not much do with them. I had several Ultrafire batteries that came together with cheap flashlights and lasers packed in a socalled 'giftbox' , and those appear all pretty ok.

These obviously use C cell shell. As fake as it gets. There is some 500 mAh lipo inside or something like that.
Check the feedback for “10x” sooooooooooo funny :bigsmile:

I actually got one of these by mistake from banggood, and they are FAKE… They weigh next to nothing, showed a full charge after 1 hour of charging, and where down to 3.2v after 18 hours of storage, I will take it apart……

Hm… this has NO pcb, holds 2.9v with a 2 amp load

i see no evidence of a protection board either.
read the fine print on the cell.
life is around 10 years.it is GREEN.
good luck on that and whoever printed that is colorblind.it is RED.as in FLAMES!
the 7200mah for the lot of 6 is probably spot on!
