Let's do batteries again!

[thewomenfolk]

What does 'protected' batteries mean? I found a battery ad that says...."A protection circuit is attached to the battery to ensure that you do not overcharge or over discharge the battery." Is that what it means, or does
'protected' mean something else?

Also, if I get 16340 batteries for my Super T2, what mAh should it be, 800, 880, 900, 1000? What's the difference?

 

[bearscreek]

I'd say you got it basically right about protection, and I'd say the more mAh the better. That just means, in theory, how much charge the battery will hold and for how long. For example, the standard e-cig batteries have a very low mAh (like I think the 510 is around 180), so that's basically why they poop out so quickly.

 

[jboze]

Pretty much spot on about the protection. Supposed to prevent the batteries from discharging too far so that they won't recharge. Also, the mah is usually overstated by manufacturers so don't worry too much about what the mah reading is. Just get some decent 16340s and you should be ok.

 

[thewomenfolk]

Another question....one package calls the batts 'lithium' and another package calls the batts 'Li-ion'. Which should I get and is there a difference? (the Lithium says its protected but the Li-ion doesn't mention protection)

 

[BrockJ]

Li-ion is Lithium Ion. Their are protected and unprotected batts. Just depends on what your wanting and or buying.

People call the lithium polymer LIPOS.

Potato / Potahto - Tomato / Tomahto

 

[thewomenfolk]

So if the battery is simply called 'Lithium', it's a Lithium-Ion?

 

[jboze]

So if the battery is simply called 'Lithium', it's a Lithium-Ion?

Yep. Just a shortened form.

 

[BrockJ]

No.... if it says lithium it contains lithium as the anode.
Li-Ion (carbon Base liquid) / Lithium Polymer (polymer based carbon ion)/ Li-Fe (which is an iron disulfide / Think Alkaline)/ Lithium Cobalt Etc..

 

[jboze]

I stand corrected!

 

[thewomenfolk]

I stand educated! Thanks so much to all of you for helping me understand these complicated things.

I vote we get a sticky one day (when David's finished my PV's ) that explains all in one place what batteries and chargers are recommended for each of the Super-T's, and maybe explains a few things about protected and unprotected batteries, and other things we might need to know, etc.

I get confused on David's website because in one place it says the Super T1 uses cr123a batteries..

"The Super-T1 runs on a standard 3.6/3.7 volt Li-ion Cr123a/16340 rechargeable battery rated at 880 mah, which is 5-8 times the capacity of stock batteries.

Available 6 volt extension sleeve. Allows you to run two 3.0 volt CR2's for a 6 volt vaping experience.

Is the difference in the two, CR123A and the CR2 the length ?? or the diameter ..

​

The super 6 uses CR2s? and CR2s are the ONLY WAY to get 6 volts ?

I hate battery stuff ...

So good to learn something each day.
Especially if it's about vaping.

Yes, that is correct, the Super Six is thinner then the old T1 and thus can only fit one 14500 for 3.7 volt vaping or two Cr2's for 6 volt vaping.

Hope that helps!

No worries Hokie, you got it

Just depends on what you want for options.
The ST1 has a locking button but is a little larger than the Super Six.

The ST1 can use a single CR123a/16340 without a sleeve, for vaping at 3.6/3.7 volts. If you buy the sleeve you can use two 3 volt CR2s for 6 volt use.

The Super Six uses a single 14500 battery for 3.6/3.7 and two 3 volt CR2s for 6 volts. (No sleeve required.)

As for size:
The number tells the size of the battery
The first two dictate the diameter
The second two are the length

16340 = 16mm diameter x 34mm long
14500 = 14mm diameter x 50mm long
Since CR2s don't seem to use the same system I measured mine at:
CR2 = 15.2mm diameter x 27.6mm long

Keep in mind these approximate measurements in the numbering system and, like most things from China tend to vary a lot.

You can however see what David has done with the different battery options. The Super Six size is dictated by the room required to take two CR2s at one time. The ST1 size is set from the diameter of the 16340 with length dependent on using one 16340 for 3.7 volts or adding the sleeve and using two CR2s.

OK now I have begun to ramble and probably making no sense at all.

If I am really lucky I may have helped - if the norm rings true, I probably added to your confusion.

Best of luck
Bob

P.S. Then comes the whole issue of the ST2 and the Minni batteries.
P.S. P.S In chapter 3 we will discuss protected an unprotected sizes
P.S. P.S. P.S. Lets keep chapter 4 simple - Buy 4 each of 16340, 14500, CR2 and 10440. Then order one of each of David's creations and you will be good to go.

 

[thewomenfolk]

Okay, now I've got all the batteries I'm going to need for my Super-Six and Super-T2 on order. I hope you understand this is a great feat.

Thanks to everyone including David who's helped me begin to get all this battery stuff straight!

Here I am writing an entire book, showing my lack of actual knowledge and you sum it up in one sentance while beating me to the "submit reply' button by a hair.

LOL

Thanks olderthandirt
I just read what I typed and am really confused now.

Fortunately took I my on advice and followed chapter 4.
All batteries are in and charged - just need the toys to go with them.

More battery info...

CR2 are 3v and unprotected. I do not like the idea of using them in series because of this. But this doesn't mean you should not use them - you just need to take a little extra care. Throughout the course of a day, switch them around - put the front battery in back and the back battery in front. This will help keep both batteries close to the same voltage. With unprotected batteries a large voltage difference can cause problems when used in series. Also, use a good charger that has circuitry to prevent over-charging. Buy a cheap multi-meter and check the voltage, and keep them in pairs of similar voltage (+/- 0.2v should be fine). Dispose of them (properly) at the first signs of problem or confusion (like it doesn't seem to hold a charge, etc) or heat (warm batteries are fine, hot batteries are absolutely not fine).

RCR123A are 3v and are the same size as 16340s - but 16340s are 3.7v.

Tenergy RCR123A 3v are LiFePO4 construction, not Li-Ion like all the other batteries we use. LiFePO4 are not "protected" in the same sense as most others. LiFePO4s are inherently safer and do not need the PCBs that Li-Ions use for protection. They require their own charger, and should not be placed into a charger made for 3.7v batteries! They will generally read 3.7v off a fresh charge but quickly drop to 3.2v under load, and soon to 3.0v. LiFePO4 produces more consistent power - a 900mAh LiFePo4 will last longer in your PV than a 900mAh 16340. This is because LiFePO4s produce more consistent high-drain power than Li-Ion. Li-Ion batteries will slowly drop off and won't produce vapor, yet they still contain plenty of "juice" - just not enough to power something hungry like an atomizer.

I like the Tenergy RCR123As 3v batteries quite a bit.

2 x 16340 is the same size as 2 x RCR123A - nice to switch between 7.4 and 6.0 volts.

AW and Pila batteries are about the best you can get, with additional safety features and more honest mAh ratings. However, they are about twice as expensive as UltraFire or Trustfire. AW batts can be purchased from LightHound.com, Pila from Pila USA and some other places. Note that Pila batteries use different numbering system.

The Pila IBC charger is probably the best charger you can buy - for $50, about 3x what you'd pay for an UltraFire WF-139. But it has some built-in testing and safety circuitry, and it is very, very good good. The UltraFire WF-139 is the charger I use, even though I want a Pila. The WF-139 is far better than the TrustFire TR-001 that looks similar and is commonly distributed with PVs. Again, some built-in safety features make the WF-139 a better, safer charger. For about $15-$17.

A charger like the WF-139 won't charge 16340s - the negative prong is too far away so you need spacer blocks to fill the gap. It's well worth the $20-$25 for a WF-139 and two spacer blocks and get rid of the 16340-specific charger which does not have the safety features of the WF-139.

RCR123A are 3v and are the same size as 16340s - but 16340s are 3.7v.

RCR123A and 16340 are both size specifications. They are not voltage specifications.
23A means 2/3rds the size of an A battery. 16340 means 16mm diameter x 34mm long and 0 means round. Do not assume that if it says RCR123A it is a 3.0V battery, same for 16340, it could be 3.0 or 3.6 instead of 3.7. Read the voltage specification before you buy anything.

Here's a 3.6V RCR123A: RCR 123A 3.6V 650mAh (2.34Wh) Rechargeable Li-ion battery - Industrial only (1 PC)

Tenergy RCR123A 3v are LiFePO4 construction, not Li-Ion like all the other batteries we use.

This is somewhat misleading, Tenergy also makes Li-Ion RCR123A 3.0V with a PCB and FET. I use this batteries all the time:
