New Solarforce RCR123A Battery Test



These are the new RCR123A batteries from Solarforce ...
DIA = 16.7mm
Length = 36.1mm
Protection Circuit [ cuts in @ 3v to protect against over discharge ] 


I was lucky to get my hands on some of the new Solarforce batteries . And I would like to thank http://www.solarforce.hk 
for the opertunity to test the new cells . The first thing I wanted to test for was discharge levels , in other words 
how well the cells are matched for discharge , and to say I was suprised is an understatement . The cells are very well 
matched , and I find no fault in this regard . I tested at different levels and if they were not to close to call they 
were the same [ results ] , for example , with the SSC P7 pill in the L2m , I got 2A even for the cells tested . This is 
better than expected , considering the little RCR123A's would have been pushed very hard .

Testing the older Solarforce RCR123A resulted in 1.79A in the SSC P7 
The AW RCR123A did 1.81A 
And the new Solarforce RCR123A as mentioned did 2A even .

Now this runtime graph is going to look a little different , simply because Im using a single mode low voltage Solarforce 
pill in my L2M [ 1 x CR123A with single mode XR-E R2 ] , which would be Buck Boost ... which hopefully explains the curve .. 



Now termination came about from the protection circuit activating at 3v under load , all batteries tested , were terminated by the Protection circuit  ...
And as can be seen , the new Solarforce RCR123A perform very well . 
They performed well in discharge [ well matched ] , as well as capacity , and look to be a serious contender for your hard earned money .

Update 

I put a cell through my [ new ] balance charger , Discharge rate was 0.5A and ended at 3v , resulting in some 721mA being discharged .

 Always remember , the easiest thing in the world to do , is to expel hot air from your lungs and through some vocal chords ..
The resulting sound may , or may not be worth listening too ….

Wow , those looks very good!
Nice review, Thanks!
I hope the "consumer" also will be good. (The test version are sometimes better, as the final production)
I'm thinking, i will buy 4-6 from the 18650 V2, but i wait your review!
Can you tell us the physical dimensions?  ("Important" data, for some flashlight)

I usually include DIA + Length ...  Ive just started testing the 18650 

DIA = 18.1mm

Length = 67.7mm , it will take a few days

ARGHHH... my older version just got delivered 4 days ago !!!.

 2.0 amps for the new models, 1.79a for the older version. What does an extra .21 amps (10 percent more) mean for my Solarforce XP-G bulb ?, will it give my 320 lumens bulb another 32 lumens ?

Just depends ...   Higher current usually means more output , but less run time ..

These new cells , offer both , better discharge , and improved capacity ..  But check out to make sure they fit , as they are on the long side ... [ New cells ]

Saw them before new years , but not ATM ...

I'd send them an email asking them to combine the shipping cost as obviously $18 is madness. They should just charge you the $6 even that seem a little over the top.

Ahh good, good. It was possibly just a mistake on the listing, I know things can get complicated if you're listing in multiple eBay domains.

You guys are not going to like this ...

I put the Solarforce V2 RCR123A through the Imax B6  @ 0.5A  and some 721mA was discharged to 3v Tongue out

Thats good , especially considering everyone exaggerates capacity ..

Or maybe the parameters are different , like the cells are discharged to 2.5v or something ?  Anyhow , 721mAh is very good .  

What I meant by people not liking it , was , ATM , these cells are a little bit hard to find ...

Thanks old!   It looks like my next RCR123A puchase will be from Solarforce.

Hi old4570,

Just want to make sure, is it true that the old Solarforce is not a good one (according to your thread in here http://budgetlightforum.cz.cc/node/1327) and the new Solarforce is prety good.

New Solarforce has more length compare to the old one, will this be a problem to some of flashlight?

Thanks.

Yes the new Battery is good , No , the older batteries are just that , old , they did not age well .. How the new ones will age ? 

Yes , they are long , in fact a little longer than the protected Flame Trustfires , and yes in some lights , that might be a problem . 

I use them in my A20 T5 , and I had to mod the light a little to make room for the batteries ...

Atm, Solarforce is selling 2 types of RCR123’s

A white one with blue text, and a white one with black text

Is the blue text battery the newer version to the black text?
Or
the black text battery is version 3, and version 1 is no longer sold?

Secondly, is the diameter of both batteries the same?
I’ve heard the blue battery has a 18350 size.
On the Solarforce page, it says the white one is a CR123A, then says it’s a rechargeable, then on the battery it says 16340 which sounds like an IMR.

Blue text on white = New 

DIA = 16.7mm
Length = 36.1mm

 

Black text on white = Older 

Dont own any ATM

Then I bought 2 of the wrong ones > <
The black and white version looks so respectable though.
Thanks for the info, old4570

Do you think both the RCR123 versions can handle 1.5A safely?

Yes they can but run times will be short.
