Re: 16340 = cr123a ?

They are the same size cell, but sometimes saying "cr123a" implies a primary (3v) cell while "16340" generally always means a rechargeable li-ion cell.

That is an IMR cell. They have a bit lower capacity but have very high discharge current. that cell can discharge at 4.4A!

They have regular ones too, and trust me they are much higher capacity than all these xxxxFire cells.

Edit: here ya go

@Goldpunch, here is a link I used to use quite a bit when I was new here and trying to figure out all the weird battery sizes.

Rechargeable Lithium Battery Information - Protected vs. Unprotected Li-Ion Batteries - Lithium Ion Battery

Size Chart
This is a chart that illustrates the approximate sizes of the various rechargeable lithium batteries that we sell. The numerical designation of the battery gives an approximation of the size. For example, a 10280 battery is approximately 10mm in diameter and 28mm tall, the final 0 indicates that it is round. Please note that the sizes are approximate, and some batteries, especially protected batteries, may be too large to fit your particular application, please check the exact sizes before ordering.
10180 battery - 10mm x 18mm (1/3 AAA size)
10280 battery - 10mm x 28mm (1/2 AAA size)
10440 battery - 10mm x 44mm (AAA size)
14250 battery - 14mm x 25mm (1/2 AA size)
14500 battery - 14mm x 50mm (AA size)
16340 battery - 16mm x 34mm (nominal CR123a size)
17335 battery - 17mm x 35mm (nominal CR123a size)
17500 battery - 17mm x 50mm - slightly wider than CR-123, fits most lights, but 1.5 times the height of the typical CR-123a battery - two of these will generally replace three of the CR-123a batteries

17670 battery - 17mm x 67mm - about the size of two CR-123a batteries, but less overall voltage, 4.2v max vs. 6v max from two primary batteries

18500 battery - 18mm x 50mm - wider than CR-123a, about 1.5 times the height of a single CR-123a battery, these will only fit lights designed for their wider size

18650 battery - 18mm x 65mm - wider than CR-123a, about 2x the height of a single CR-123a battery, these will only fit lights designed for them

Re: 16340 = cr123a ?

the final 0 indicates that it is round.

People always say that the 0 means its round, but I'm pretty sure that's not the case.
The way I think of it, the first two digits are the diameter and the rest of them are length with one decimal place.

ex.
18650 18mm dia. 65.0mm long

15266 (aka CR2) 15mm dia. 26.6mm long

CR 2032 20mm dia. 3.2mm long/thick

those last two are both round, but neither have an 0 on the end.

I guess they are original, there is nothing to indicate that they are counterfeit.
I buy a lot of my batteries through Battery Junction, they have fast shipping and good prices.
