Thoughts On JSBurly\'s New Batch Of 4.2V 123R\'s!
Don't look for technical data here as I'm not a technical sort of guy. I just wanted to let folks know Jon's new batch of 4.2V rechargeable 123's, (that are now on his site!), have some nice improvements over the originals.
These cells are the higher voltage rechargeable Li-Ion 123 cells and work wonderfully on single cell lights such as the Firefly, McGizmo lights, KL1 heads, etc. Because they are of higher voltage, they add that extra "kick" to your one cell lights that you can't get from a regular nominal 3V 123 cell. As an example, I'm running a KL5 head on one of these and I can get full brightness like I was running it on 2X123's that it was made to run on. Of course the runtime is shorter but hey, they're rechargeable! They are also fully under/over discharge protected and are as safe as you could want. These cells are safest and best with one cell lights.
All in all, the originals are a great product and most work as advertised. However, (as some of you are aware of), the original batch of these 123R's had some height uniformity and construction problems and a small number were found to not hold a charge. As an example, none of the original batch would work in my particular Firefly, (because of their shorter height), without some modifications that I refused to do.
With this new batch that Jon is currently selling on his site; www.JSBurlys.com the height uniformity issue is resolved. The height is now uniform from one cell to the other and that is good news! These now work perfectly in my Firefly with no alterations whatsoever to the light or the cell. The examples I have, all came off the charger, (after resting a bit), at 4.1-4.2 volts. These also have improved venting over the original batch which is a minor point but a plus nonetheless.
I have to be honest and say that these Rev. 2 cells are not perfectly constructed and still have a little ways to go. Some of my examples exhibit very small imperfections in the wrappers but all in all, they are much improved over the original batch. As earlier stated, the BIG improvement with these is the height of the cells are now uniform, no more "crushed" look to any of them and they will now work with any light that accepts a 123 cell, as long as it can handle the extra voltage.
Jon worked extremely hard to bring all of these rechargeable 123's into fruition and should be commended for that and for his continued improvements to them. At $20.00 a pair and $28.00 for a pair and a charger, these are a bargain! Jon also sells the nominal 3V rechargeable cells for a slightly higher cost but all of these will save you BIG in the long run. I LOVE rechargeable Li-Ions as unlike NiMH's, you can charge them, put them in your lights and spares carriers and they will hold their charge for a LONG time.
Jon is one of our better dealers here on CPF, if not the best! He's honest and tries hard to please. Thanks Jon for continuing to improve an already great product!
