CR123A batteries for WL Sonar

I have ordered a Sonar from Wicked Lasers. The specifications state that it uses CR123A batteries.

So I'm wondering if it will function with "RCR123A" - the rechargeable version of the CR123A battery. I'd like to purchase some from Amazon. I've heard that WL says that their lasers are not certified for use with these rechargeables, but I interpret that as meaning that they haven't tested them using those. As a related question, the Wicked Lasers Pulsar (red) uses two AAA batteries. If I purchase the "Sanyo Eneloop Rechargeable AAA" batteries from Amazon, will the Pulsar function with these rechargeables just as it will with the single-use AAA's that are included?

Another question: Does anyone know of any specific RCR123A batteries that will fit in a WL Sonar? I ask because I read a review or two in which the writer stated that the rechargeable cells he ordered didn't actually fit in the tube. I would think that another company's version of the exact same type of battery would be the same size, but apparently not. I'm wondering if anyone knows of a specific brand of RCR123A's that you've tested with this laser.

And finally: I notice that the Wicked Laser "Universal Li-Ion Charger" that they sell for use with their 18650 batteries also has two horizontal slots that look like they might be for the RCR123A. Does anyone know if this is what those two slots are for? The specifications doesn't specifically list any information about those slots.

Thanks!

No most rcr123 cells are 4.2v cells. the Sonar requires 3.0v You have to make sure they are the 3v kind.
Also the charger you are referring to is for the 4.2v cells, so no.

Try this from lighthound here in the US
3 Volt RCR123a Unprotected Battery
and this
Nano 3 Volt Charger

I actually emailed Lighthound about this a few days ago, and they replied that none of their RCR123A batteries are truly 3.0v, even if they're marked that way. All of them actually put out 3.6-3.2v. I don't know if that's enough to damage the diode or not, but I wouldn't be inclined to risk it myself.

The email itself read:

"Sorry, there are no batteries that will work. The batteries that are rated at 3 volts, including ours, actually charge up to 3.6 volts and deliver 3.2 - 3.4 volts over the course of their discharge, so they are too powerful for a 6 volt flashlight."

Try Juice rechargeable CR123A batteries, I believe they are 3.0V exactly.
