Panasonic NCR18500A 2000mAh Battery

[anavidfan]

Anybody use these? I need a new batch 6-12 and figure these might be good in addition to my AW button top 18500/490's.

They sell them at a popular place where many here buy their batteries, but am confused as the site also has a disclaimer on almost all the battery description.Its on almost all the pages with batteries in the warning part.

DO NOT USE WITH E-CIGARETTE, VAPORIZER, OR SIMILAR DEVICE

I use the other green panasonics in the 18650 size, so just want to make sure Im not missing something.

Thanks all

2000 mAh is a relatively high capacity in an 18500 form factor. That means it has a relatively low CDR. The only number I can find is 3.8A, but I'm not sure how authoritative that is.

I do not know those batteries and am unsure if their rating is accurate (you can really only find that out by looking at Mooch's blog and test results, he has a handy table of authentic batteries he has tested and recommends, and there is a handy table that also lists the reputable suppliers.

You will probably find that warning however with most batteries you buy. Recently, IMRbatteries.com (which is my preferred "approved" vendor) has put that warning on batteries for e-cigs because they don't want to be sued in case of battery incidents with inexperienced users. So, it doesn't mean you can't use them, but I would be more inclined to buy directly from an approved vendor, and usually the big three batteries are Samsungs, LGs, and Sony's. Approved vendors are often LESS expensive than other (rebranded) batteries so it may be worth checking out.

Best of luck,

Anna

Those NCR18500A batteries have a Very Low Constant Discharge Rate (CDR) which the manufactured says is 3.8 Amps.

So unless someone was Vaping at like 10 Watts or Less, I wouldn't think they would be a decent choice in a Regulated Mod.

And No Way could they be used in a Mech Mod.

Assuming that 3.8A rating is correct, if someone was vaping at 1.1 ohm or higher on a mech that battery theoretically could be used according to my Ohm's Law calculator. Back in the day, before there were regulated mods, that's how we vaped with cartomizers and cartotanks on mechanical mods.

And as far as Orbtronic's warning not to use Li-ion batteries in e-cigarettes, that is a warning that is extended from the battery manufacturers themselves.

...

Theoretically this is True.

But given that there are No Safeguards when using a Mech, I would Never suggest using this Battery, or any Battery, where I was Right on the Edge of it's CDR Rating.

So a Mech User would want to be more at something like 1.4 or 1.5 Ohms. And at those Ohms, they probably are Not going to get a Very Good Hit.

And the Desire to go with a Lower Ohm may creep in. And that is where a Big Problem could arise.

Thank you all for the info, and again, Im torn, I will stick to those batteries Ive been using for years. I liked the rating on the Pans, but I could not find the amp rating anywhere.

I usually use AWs (18500/490) and vape at no lower than .85 to 1.2 depending on device/ battery.
18500 is my favorite form/ size. I use AWs and Efests, but since I use the same Pans on my 18650 devices, saw the mah and thought wow, more use time.

I searched all over for Mooch's charts and ratings, and for 2017 could not find anything on 18500's.

SO its either pay 10 a pop for the AWs or more effests , thought the Pans were a great alternative. I did find that Sanyo makes some 18500 with a bit better mah rating than the AWs and bit less expensive, but again, cant find any actual user info.

I am in total agreement with you. However, we don't know what kind of vaper anavidfan is. If he is a Tootlepuffer (high resistance, low wattage), then 1.5 ohm might be right up his alley.

Yeah... Not even sure if anavidfan uses a Mech.

I just Don't like to see people get Batteries with such Low CDR's. No matter what they Use. Because there is so little "Wiggle Room" for them to use Different Ohms/Watts.

Although I Do Understand a 18500/18490 user's dilemma. Because there just Aren't a lot of choices out there for them.

It's kinda that Classic Tradeoff. More mAh but Less CDR. Or more CDR with Less mAh.

What Mod(s) do you run these 18500/18490 in? A Provari?

Yeah, I don't believe Mooch did any testing for the 18490/18500 batteries.

I checked my database and found that the AW 18490 battery's specs are 1200 mah with a 15 C-rating. Using the battery amp calculator below that's 18 amp CDR. That's pretty darn good for a 18490 battery. That would imply that 0.23333 ohm would be the lowest you could go. However, using that resistance would severely affect the capacity since its only a 1200 mah battery to begin with.

I would never trust the advertised specs of an Efest. I couldn't say for the Panasonic's specs either. Many folks trust their spec ratings like they do Lg, Samsung, and Sony as they are all major manufacterers of batteries with reputable specs.

Hi, Im almost exclusively a mech user, I love em.
Depending on what I using, and the atty, I vape at no lower than .85 to 1.1, simple single coil.

18500/490 is my favorite in form and size, mostly due to the size as my hands are rubbish. I use AWs and some purple Effests. When I use 18650s , I use green Panas, or LG or AWs.

For my 14650/500 again, mostly AWs, but I did pick up some 14650 AWTs and am enjoying them. When I use my little slim mechs, I usually build at 1.1, because the small slim atties tend to be warmer.

Its so hard to choose, so much conflicting advice, I figured since I do use the Pans in 18650 form that the 18500s would be fine, but like you all found the amp rating is kinda on the low side. There are some Sanyos but they are harder to find, I will have to see if I can find the amp rating on those or just stick to the AW and Effest.

Every year I replace my older sets, so that means 6 to 12 new 18500 batteries.

I Wouldn't recommend those NCR18500A's for a Mech user vaping in the .85 ~ 1.1 Ohm range.

They just Don't have enough CDR even if the OEM's rating is True.

Panasonic makes a variety of different 18650 cells with different suffixes and different CDRs. They're all the same green, so you can't judge them by the color.

Thanks to everyone, might go with my usual AWs and then I keep hearing good things about the AWT? theres a red label and yellow and they both say 18A , which Im sure is more like 15, but still better than the amp rating on the Sanyo and the Panasonics

These are the AWT in looking into right now

 

[AzPlumber]

I wouldn't use one right in front of my face without knowing what the NCR chemistry is and how it behaves during a thermal runaway.

Mooch has only tested/published results for two 18490/18500 batteries:

18500 Test Results

• Basen Black 22A 1100mAh 18500 Bench Test Results...a wildly overrated 12A battery
• Efest Metallic Purple 10A/1000mAh 18500 Bench Test Results...a decent 10A/1100mAh battery

Based on Mooch's AWT 18650 battery tests, I'd refrain on using their 18500. AWT seriously over-rates their battery specs:

• AWT 40A 2600mAh 18650 Bench Test Results...only 20A/2500mAh, might be a 25R2
• AWT Yellow 40A 2600mAh 18650 Bench Test Results...only a 20A battery
• AWT Red/Black 50A 2600mAn 18650 Bench Retest Results...preposterously overrated, now lower grade
• AWT Red 35A 3000mAh 18650...ridiculously overrated, not IMR
• AWT Red 40A 3000mAh 18650...enough is enough, just don’t buy it.
• AWT Black 50A 3000mAh 18650...obscenely overrated, do not buy
  
• AWT 35A 3500mAh 18650...laughably overrated, only an 8A battery, do not buy

Only one cell was tested at 7A, and by the looks of the curve looks like it was the lowest performing one. About 70mΩ brand-new DC internal resistance.
Perfectly fine for coil loads down to 0.85Ω, because:
I = Vmax / Rtotal = Vmax / (Rload + Rcell) = 4.2V / (0.85Ω + 0.07Ω) = 4.2V / 0.92Ω = ≈4.565A
Rload includes other negligible resistance parts of the circuit also, of course.
Looks optimal to me and provides great runtime since it can still provide above 3.2V hits at 3.5V unloaded cell volts with the aforementioned 0.85Ω coil load.
