Rechargeable batteries to TK10 ?

[Mr Luma]

I wondering what sort of batteries i can use in my new TK10.
I have a couple of (Grey) Ulrafire Protected CR123, 16340. (Max 4,2v)
can i use them without any risk to damage the bulb? Or shall i buy new Ultrafire 3v. (Max 3,6v) ??
Does the (Grey) protected UF CR123 fit in the TK10 batteri tube ? :candle:

I have Ultrafire 16340 grey cells too but they are too long to fit into my TK10 and it is not possible to screw in the tailcap.

Old light blue 3.0V protected cells are on the contrary exactly long like primaries and they fit beautifully.

I understand that the use of RCR cells in this light is not a matter of voltage but of length. It appears that the circuit can take at least 8V.

From where can i ordered this "Old light blue 3,0v protected" ?
Please give me a link if it's possible.

I notice that the protected R123A cells that AW sells in the Marketplace (here) appear to be identical in size to primary batteries. They would then fit into TK10.

Any specific experience from somebody else? :thinking:

Hi Mr Luma,

I have both the silver Ultafire and Trustfire RCR123s. They are both too long to fit comfortably in most lights. I highly recommend AW's 3.7v RCR123s. Better quality, protection circuit, and they actually fit in all my lights.

You can get them from AW himself. Lighthound and Fenix-Store also sell them.

Edit: You want to use 3.7v RCR123s for the TK10, T1, and P3D.

Sorry...but AW:s it's to expensive with shipping to Sweden. I must find something much cheaper;-) Like UF ot TF. Please give me advice.

It is unfortunate that it costs too much to have the AW's shipped there, because i use them in my TK10 and they work well:shrug:...i will see if i cant find out what else would fit. good luck

Fenix-Store ships free worldwide

Fenix-Store ships free worldwide

Yes..i know, but the price would bee $36.00 USD, if i bought four AW:s CR123. To much for me.

I'm moving this to the batteries sub-forum, where you will find more information on batteries, including numerous posts about the very poor reputation of Ultrafire cells.

BTW, I think you owe me a reply to a PM I sent you.

I have done after your advice. I ordered six AW RCR123A from the Fenix Store. Price included free shipping to Sweden = $54.00 USD.
I really hope they work with my Ultrafire Charger WF-138. ? :thinking:

The Fenix TK10 does work with 2x 3.7V rechargeable Li-Ion RCR123 - as others have noted it is a matter of fit.

In Fenix TK10 Comparison Review Post #16 I took beamshots of the TK10 on 2x 3.7V RCR123 compared to a T1 on primary CR123A - this showed TK10 was about same brightness on the 3.7V rechargeable RCR123.

Lithium batteries are very powerful, and there have been reports of explosions - I would strongly suggest Protected RCR123's from a reputable source, and to turn off and stop using the light at the first signs of dimming to prevent over-discharge of the batteries.

Thanks for the information...

the TK10 doesnt dim---its designed for 3V cells...and it will draw them donwn till they cant deliver enought current anymore.....i dont know what voltage it is...but maybe its too low for unprotected cr123

 

[jirik_cz]

TK10 has low battery warning (at around 5V in high mode).

 

[Nos]

the deep discharge protection of the most li ion batteries kicks in at 2,75 V. maybe 5V from 2 cells is too low? ... but dont ask me im not taking any risj with this chemistry

 

[jirik_cz]

5V is bad for the cells, but is not dangerously low (I think). I also recommend protected cells for TK10, AWs work great

Mr Luma, if you are talking about this charger, http://www.lighthound.com/index.asp?PageAction=VIEWPROD&ProdID=2515, then the answer is yes. I have the Ultrafire WF-138 charger and I use it to charge my AW RCR123 3.7v, 750mAh batteries... just remember that there is a selector switch on the side and you have to choose the 3.6v setting ie. move the selector to the LEFT.
