can two CR123a batterys be used instead?

No, for 2 reasons: the CR123a are too big around to fit in the battery compartment and 2 CR123a together are too much voltage for the LED. You can fit 2 of the CR2's, but they are also too much voltage for the LED. I use AA rechargeables and 14500 batteries and they work fine. I hope this helps and have a good day.

It's not recommended as the charge and discharge rates are different for the two batteries. It's best to use two batteries of the same capacity.

Yes this does use the CR2032 battery, I haven't had to replace mine yet though.

Lithium 3V photo batteries (CR123A) like these: DL123A Duracell Ultra Lithium 8 Batteries-CR123A

If u are talking about replacing 2 cr123a batteries than the answer is yes. Thos battery is a tad bit wider but most flashlights etc. accomadate for the wider profile.

It takes two CR123 or DL123AB batteries. Use lithium batteries for longer life.

I'm not sure but it seems that the CR2 batteries are very similar in size and voltage to the cr123 batteries which is stated as acceptable.

You probably can but I doubt you would have room for both batteries. I have never tried it and never would.

I don't think so. I looked in several cross reference charts for batteries and they are not mentioned as being compatible. Additionally a CR2032 visually appears to be slightly larger than the CR1632, but I didn't have a CR1632 to make a physical comparison.

It uses the 18650 3.7V. I may accommodate two CR123's if I recall correctly. Hope this helps.

I use a small one purchased from Radio Shack. One of the options is a 3V lithium which is what the CR2 is.

One of these does work to replace two CR123 batteries IF the device is designed to handle either. For instance I have two Fenix flashlights that both use 2 x CR123 batteries. One is an older model and a 18650 does not fit. One is newer and was designed to work with two CR123 or a single 18650. If your device does not state it can use either type its a tossup - as previous posters noted the diameter and voltage and terminal shapes are different.

You can use that battery as long as the physical size is the same and voltage is same as 4228, and new battery has to have same or more voltage and amps but no less.

I think you need this charger: Trustfire Multifunctional Universal Lithium Ion Rechargeable Battery Charger for CR123A, 16340, 14500, 10400,... because it can accommodate both of the batteries you mentioned. It is $9.98 from Amazon... No I don't work there...

i just looked that flashlight up on amazon and it said it takes 2-cr123a or 1-... 18650 and that is the battery you are asking about ...so yes you can use that battery

No, but you can use the CR123A, just don't use more than 3, and of course the 18650, and 3 of them as well.
