Fenix P3D CE Premium Q5 / Fenix TK-11 - Rechargeable Batteries

[FelixGR]

Dear Ladies and Gentlemen

Since I am a rookie as far as flashlights are concerned,
I came to find a forum in order to "enlighten" myself with
this wonderful world of light.

Please forgive my "stupid" questions :thinking:

My buddies bought me a Fenix P3D CE Premium Q5 flashlight
and I can tell you I am fascinated by its performance

I am also planning to get one Fenix TK-11 and since I tried
to look for batteries for both models in the Net I got lost!!!

So please I need your help for getting out of this
complex world of BatteryOPS...:candle:


My Questions Are

Fenix P3D CE Premium Q5

1) Will it Take Rechargeable Batteries (if yes what type? RCR123, 123A etc etc)
2)Will it take 18650 cells
2) Both Protected & Unprotected?
3) What should be the max voltage of those (max mA doesn't play any role-or does it?)
4) Any particular brand(s) that will fit in the tube? (length & Width?)


Fenix TK-11

1) Will it Take both 18650 and CR123 Rechargeable Batteries (if yes what type? RCR123, 123A etc etc)

2) Both Protected & Unprotected for both cases?

3) What should be the max voltage of those (max mA doesn't play any role-or does it?)

4) Any particular brand(s) that will fit in the tube? (length & Width?)


For both Models

1) What (Where) should I look for Charger for both types of Recheargable batteries?

2) I need both 18650 and CR123 Rechargeable Batteries any ideas?

PS: (@admins: I am not trying to get advertisements, only a little help )


Again Thank you for your time and help!!!

The P3D will happily take CR123 primaries and RCR123 rechargeables of any chemistry. The TK11 will take CR123 primaries, Li-Ion 18650, and RCR123's of any chemistries. It is best to always use protected cells for Li-Ion. The only thing to be careful of is that some cheap protected RCR123 cells are longer than standard, and may not fit length wise in either light. Quality cells such as AW's fit fine.

RCR123's are also known as 16340's, for their size designation. Li-Ion cells are 3.7v nominal, but peak at 4.2v fully charged. CR123 primaries are 3v. There are chargers which charge a variety of sizes of Li-Ion cells, such as this one.

Thank you very much 4 the information!!! :thumbsup:

Very, Very Helpful indeed!!! :thumbsup:


1) For The charger mentioned it is not stated whether it has an
auto-off feature or is there?

2) I also have noticed that there are 3V and 3.7V RCR123 cells
are they both compatible with the two flashlights mentioned above
and the charger?

This "enlightenment" process will never end....!


PS: So Although a Protected RCR123 Cell will end up with 3.7V it is still
supported by P3D Q5 and TK11 which normally operate with 2x3V ?

Thank you again...

I thought you could only use 18650 and cr123 in the TK11 because one 18650 is gonna be 3.7V so why woud its circuit allow twice that voltage when it doesnt have too, can someone explain as i am not very sure.

Got both these lights myself, i EDC the P3D and the TK11 is my bump in the night light.

The charger linked will greatly reduce the charge to a trickle charge when the cycle is complete, but batteries should be removed promptly, and Li-Ion cells should NEVER be left unattended. This goes for any charger.

There are three primary chemistries for lithium batteries. CR123 primaries are 3-3.2v. Most RCR123's are lithium ion, which are 3.7v-4.2v. There are some cells (some Tenergy IIRC) which use that type of RCR123, along with a circuit to reduce the voltage to 3v when in use. They require a special charger. There is also a "safe" lithium chemistry known as LiFePO4, which is around 3.2v, needs no protection circuit on the cell, but is lower capacity (less runtime). 18650's also exist in both lithium ion and LiFePO4 flavors, although lithium ion is by FAR more popular.

Also, the LiFePO4 and Li-Ion chemistries each need their own specific charger.

The TK11 will take Li-Ion 18650's, and run in direct drive on the turbo mode, and regulated in low mode. It will also use any variety of CR123's or RCR123's, however runtime will be much less with either variety of RCR123's.

Excellent!!!

Roger that!

So I will now start looking for any good Protected 18650's and RCR123's (of any normal voltage say from 3V to 4.2V)...., now that we know the charger...

Thanx again for the Intel!!!

For use with the above charger, you can only use 3.7v (4.2v charged) Li-Ion cells, not LiFePO4 cells.

Again thank you for the information...


I happened to come across to some 3V RCR123's. Is this possible?
I thought they only came @ 3.7V :sick2:

Does the charger (in discussion) support both 3V and 3.7V RCR123's?

There are two ways to get 3v RCR123's. One is using a special circuit which lowers the voltage during use. The other is using the LiFePO4 chemistry. Both require a unique charger. No, the linked charger can ONLY charge 3.7v Li-Ion cells.

 

[FelixGR]

Thank you again for all your help

I am now the Proud owner of a Fenix L3D Q5 and a TK11
Both are amazing!!!

Additionally the AW 123 batteries are excellent and they are giving
the L3D great runtimes.

Great Flashlights for a Rookie!!
Thanx for all your help once more :twothumbs
