Is RCR123 Lithium Ion

[Albinoni1967]

Bit of confusion here, I know that CR123 is Lithium just your normal CR123A cells but regarding RCR123 is it actually Lithium or Lithium Ion.

Reason I asked is because on ebay I saw Nitecore RCR123 batteries and in the description they said Lithium Ion.

Hello Albinoni1967,

The R in front of the CR123 tells you it is Li-Ion.

OK a CR123 is Lithium correct, and a RCR is Lithium Ion

Yup. The former is a "primary" and the latter is a "rechargeable".

For our flashlight applications, we use pretty much exclusively standard Li-ions ("ICRs") and IMRs. IMRs are for the insane-output lights that have extreme amp draw, but have much less capacity than the standard Li-ions.

RCR123 or R123 is a rechargeable CR123 and they are usual LiIon batteries of some type, but not necessary with 4.2 volt charging.

OK thanks everyone for clearing it up with me. Now my other question here, in flashlight collection I have a Nitecore EC1 which takes either a CR123 or RCR123 battery. I know the primary CR123 is rated at 3V where as the RCR123 is rated at 3.7V, but I think the CR123 has a higher mAh (correct me if I'm wrong), so

1. Will the RCR123 give out a brighter beam ie utilizing the full 280 lumens of this light.

2. Will the LiIon RCR123 have a higher run time although its rated between 650 and 700
mAh.

Thanks

1. 310 lumens primary, 400 lumens Li-ion.

2. No, Li-ions run at a higher voltage with less mAh, you can expect roughly half the runtime on Li-ions. As usual, primary for runtime, Li-ion for output.
