The physical sizes are actually indicated by the number of the cell. Such as :

14500 reads 14mm ( dia ) X 50 mm ( length ) X O ( O indicates a cylindrical cell )
18650 reads 18mm X 65mm cylindrical cell
17670 reads 17mm X 67mm cylindrical cell

-AW
what about these?
15266  reads 15mm ( dia ) X 26 mm ( length ) X 6 ( 6 indicates? )
17335  reads 17mm ( dia ) X 33 mm ( length ) X 5 ( 5 indicates? )

15266 = 15mm X 26.6mm  The ' 0 ' is omitted due to a standardized 5 -digit numbering system
17335 = 17mm X 33.5mm

Wow!

Thanks for everyone posting their info on the battery cross reference. The size reference will also be a great asset to have on the thread. I know I would have spent days (possibly weeks) trying to get just the Li-ion cross reference to a half-way decent state. Thanks again for all the valuable info.

Sincerely,

Shaman

Shaman, thanks for bringing this to our attention. 

This is a very interesting topic - thanks to all of you for your participation, especially AW.  That's why I hereby designate this thread as a Sticky Thread.

AW (and anyone else who offers these kinds of cells) - would you mind posting some additional details on the cells you offer ?  Some info I have in mind are things like
- Protected / unprotected
- Capacity in MAH
- Some details on the level of protection, such as
  a) Protected from discharging more than X amps
  b) Protected from overcharging with more than X volts
  c) Protected (or not) from over discharging to less than X volts
  d) Discharge curves (if you have them for the more common cells)

Actual maximum diameter or the cells if they are larger than the industry standard. (Someone told me that the CR2s are slightly larger in dia at the max than the IEC standard)

I know this is a lot of info to ask, but it actually helps a lot, especially with flashlight design.  I am particularly interested in the CR2 size, but many others are going to of course be interested in 123 and 18650 versions.

The level on protection depends on the PCBs itself ( the 14mm, 16mm has different spec. than the 17 & 18mm ).
- over current cutoff is 4.5A +/- 0.5A for the 17/18mm cells ; 1.5A for the RCR2;
- overcharging is set to 4.35V;
- low voltage cutoff is 2.4V;
- all the protected cells I offer have PTC thermal protection built-in;

The slightly larger diameter is due to the PCB connecting strip running along side of the body. For the RCR2, the outside diameter is the same with a regular CR123A if you peel off the outer sticker label.

Here is the discharge curve for the protected RCR2 ( 350mAH ) under 1C :

Thanks AW for the info.  I had read those threads in detail, and they contain a lot of info on the AA  / 123 / larger cells, but I could not find much info on the RCR2.  I appreciate the additional detail, and fewer posts to read.  :)

I assume you meant that if you pull off the sticker, the RCR2 is the same size as a standard primary RCR2 ?

The 1 C discharge curve is very helpful.  Is there any chance that you have a 2 C discharge graph ?

Obviously my interest is in trying to qualify the RCR2 cells for using in my "BREEZE" CR2 side x side custom light, as I may have found a technical path for doing this, but it would run the cells at 2 C.

Thank you very much for your assistance.

HarryN,

Please see this thread for the Protected RCR2 ( fewer posts )  ;)

http://candlepowerforums.com/vb/showthread.php?t=105270


BTW, this batch of protected RCR2 seems to be 0.5mm shorter than a regular CR2 ( still within industry standard ). However, I 'll try to get them as close to standard as possible for the next batch.

Regards,
AW

AW is the best!  One of the 5 best sellers on "that other forum" I have ever dealt with...and everything always gets worked out to your full satisfaction.  I have ordered from him at least 15-20 times.

AW, you might also want to put the new Pila battery model numbers on that first page of this thread. 

Size Reference :

18650 = 168A / 600P
17670 = 168S / 600S
18500 = 150A / 300P
17500 = 150S / 300S
14500 = AA
16340 = CR123

10280 = N cell
10440 = AAA
14250 = 1/2 AA
14270 = **
14430 = **
14500 = AA
15266 = CR2
16340 = CR123A
17335 = CR123A
17670 = 2 X CR123A, Pila 168S
17500 = Pila 150S
18650 = Pila 168A
18500 = Pila 150A

Yes, AW is one of the best dealers I've worked with.

I will add a couple of comments:
10220 = 1/2AAA (AAA diameter but 1/2 the length)
10280 = AAA diameter but N length (note: thinner than an N cell) 
14270 = AA diameter but CR2 length
14430 = "short AA" (AA diameter but 7mm shorter than an AA cell)
15270 = CR2

This all looks good to me.  I captured this in my Firefox Scrapbook for offline viewing.

Hi  - I am looking for some discharge curves for AW protected 18650s and the pila equivalent.  I searched several forums for 2 hours, and I am somehow just missing it.  Could someone please post the info or a working link ?

Thank you.
