TENERGY RCR123A 3V 900 mAh batteries AND CHARGER

The Photon Shop - LITHIUM RECHARGEABLE RCR123 £37.95

These batteries are expensive but are protected, so I decided to bite the bullet and try them. On the first charge I felt the power was poor, but then I read the instructions which said that these batteries can be charged up to 5 times before reaching their full capacity. So for once, I followed the instructions.

I purposely left using the GG Transformer at 6v till I could use these batteries, as I had tried a couple of CR2’s that I had, but was not very impressed with the performance, although they were new, and could very well be like these, in the fact that they require up to 5 charges to reach capacity.

However, I don’t, these days like using unprotected batteries, for obvious reasons, so for the purposes of this review, let’s say that CR2 batteries were not tried out.

Anyway here are the statistics as taken from The Photon Shops website.

Charger features

• Smart microprocessor cut off at full charge
• Thermal, overcharge, short circuit and reverse polarity protection
• Worldwide voltage mains adaptor with supplied UK plug adaptor +12V car adaptor
• Charge 1 - 2 RCR 123 in 1.5 - 2 hours

Battery features


• 3 volt working voltage with manufacturer rated 900 mah capacity.
• Can be re-charged up to 1000 times
• Replaces CR 123A primary battery for digital cameras and LED flashlights
• Internal voltage regulator switches from 3.6 to 3V within 12 ms
• Full PCB electronic protection against over charge, over discharge, over current and short circuit, along with voltage regulation
• 16.5 mm dia x 34 length

Now one interesting addition here is the fact I have a Cold, so am vaping Decadent Vapours, Mentholyptus 18mg.
I was previously using the 18650 3.7V battery with the same juice in the GG Trans, and was enjoying the vape, but due to the Cold, was not getting much of a throat hit.

Now having changed to 6V using the Tenergy Batteries, the throat hit is instant. Yet the medicinal aspect of this juice is helping the sore throat, stuffy nose and dry mouth, and making me feel as though I had just been sitting over a hot vapour infusion! Now that can’t be bad !

Mamu recently wrote a guide to 6v vaping, which I found helpful, but as I prefer the long inhale I was biased against 6v. However, as I felt safe vaping with these batteries, silly I know, but somehow you feel, you should not exceed the short inhale advised, in case you blow your atomiser or worse, I took my usual fairly long inhale, and wow... a fantastic throat hit, and that has been followed by many more over the last four hours since I put these batteries in.
Do I feel they are worth the money?

Well they do cost a lot of money, and you are advised only to use their own charger, which charges at a faster rate than the usual nano or the trustfire ones available at Dealextreme, charging two flat batteries in around 2 hours, with an automatic cut off at full charge.

The run time is virtually the same as the non protected batteries, but if you are at all cautious of non protected batteries then they are worth the investment, plus if the claim of 1000 charges are correct, then they will pay for themselves eventually. I can’t of course verify this as I have only charged them 5 times up to now.

One major point, is that they are available in the UK and in the US from Rechargeable Batteries & Battery Chargers - 4 RCR123A 3.0V 900mAh Rechargeable Li-Ion Protected Batteries with a Smart Charger; for $32.99

excellent review of the batteries cat

i am very impressed, you are showing your true colours now,
video reviews, and now written reviews,

very well laid out and explained, easy to read and understand.

I will see if I can find some of these batteries in Australia.

thank you cat.......


I think a copy of this should go into the reviews sticky, it is well worth it ///////

Since I finally understood batteries... thanks to frog, there is no holding me back...hahaha:lol::lol:

you certainly come accross that you know what you are talking about cat, and you explain it well enough that someone like myself who does not undertand much about batteries at all, can understand at least what you are telling us.
even if we do not understand the technicallity of it all.


watch out, now, she will be building her own e-cig next !!!!!!!

Hi Christena Nice review of the charger combo!

I think the price is so unbelievably high though, for something you can get in china for few ££, that trouble in UK we have to wait, or pay premium prices ha-ha!

Tim at smokejuice does 2x unprotected ones and charger for £16.14 including shipping, if you not worried about the protection circuit they good buy for us in UK?

Also e-cigs.co.uk do a kit almost same as the one you bought for £24.99! (although you only get 2 batteries not 4!)

Tenergy Battery Charger Pack

Prodigy Battery Charger Pack (Tenergy Branded) [TENERGYPACK] - £24.99 : E-Cigs.co.uk, Online Store

These are safer than normal batteries in that they cannot explode! this kit use what called LiFePO4 batteries!

"LiFePO4 is an intrinsically safer cathode material than LiCoO2 since exothermic reactions can not occur in batteries based on this material: LiFePO4 cells do not incinerate or explode under extreme conditions. In addition, LiFePO4 cells have a higher discharge current, are not toxic and have a much higher cycle life than LiCoO2 cells."

Have some of these on way for my bulli extreme so will report back after testing them :D

yes I would be interested to hear how these go.

The kit I got included 4 batteries which are 900 mAh compared to Tim's which are 750mAh. So really price wise, there isnt a great deal of difference. Also a set of two batteries sell for around £10.

One thing I didnt mention though, I got a free laser light key ring, very handy for those dark nights, when the key never seems to find the hole...

I did find though that you do have to charge and re charge them the 5 times before they pulled at all.

So I would be very interested in how you get on with those, protected are the way to go, and hopefully the prices will come down. Fingers crossed .. :)

Great review Christena.:)

I do understand about the benefits of the protected batteries, but I can't justify spending nearly £40 when I can get a fairly decent unprotected set with charger for a quarter of that. I just have to be a little more aware using and charging them.

I will certainly be more keen on going down the protected route once these kind of batteries are a lot cheaper......

I agree they are very expensive, but there is one more factor to consider, and that is longevity..

My hubby has just thrown away some CR123's that are 3 months old, and are no longer holding a charge. So a comparison has to be done against those.

And for that one...only time will tell....

No problem Moog, thanks for pointing me in the right direction !

Lisa and Funky.... Tenergy state that these batteries will survive 1000 charges, lets just wait and see.....

I think the formula can only be determined from this point on, as Tenergy have not had these available from US and UK suppliers till very recently. So its back to ...time will tell.

I agree that the Ultra Fires and Trust Fires etc from China are cheap, very cheap, but if you work it out, the ones I have here have been charged once a day for 3 months. So thats 90 charges, and for ease of maths, lets say 100 charges

100 charges = 90 days
1000 charges = 900 days

Now if that formula works out correctly.. then the extra cost is well worth it.

Somehow I doubt it, but I will let you know in 3 years time...hahaha

Due to battery rotation, no battery that I have is ever charged more than once a day.. and to be honest some are left 2 days.

No Funky, I wouldnt say they get hot, warm, but even then, Im very safety conscious, so check them regularly.

These batteries were bought when I bought the SD for hubby, that was 3 months ago, and at the time I bought 6 new ones, and was given 4 by another member.

All have been numbered.

The 4 from another member, went in the bin around 10 days ago, as they stopped holding a charge.

Now these are going the same way. At least three of them are dead within 30 mins of vaping.

But they are not binned yet... so lets see how it goes.

One thing I have not done, but will put that right today..

I did not check the Tenergy batteries with a multimeter, before and after. But will do that today and post the details.

If a battery is 1000mah that means it can in theory deliver that amp for an hour or 1C. Of course not all batteries can do that without something bad happening like loss of charge/discharge cycles in its life. The less current you take out the looonger it lasts! I wonder if our CR2 batteries and other batteries from DX are exceeding their C discharge rate? The atomiser wants an amp but will the little batteries provide? They don't tell us usually what the discharge rate is!!

were your SD batts protected 3.7Vs? if not that that could have contributed as well, i never go below 3.4Vs on3.7V batt before i recharge them, never go below 2.8 with 3Vbatts

funky they were not protected. Hubby takes 2 or 3 with him when he goes out to work and as one tails off, changes over.

I have used a MultiMeter on them, not all the time of course, but readings have always been around 3.5v.


Tribal, you are right, no one tells you discharge rate, although I think I saw something on Tenergys website.. will check it out.
