Weird battery question

As amazed as I am about how much I’ve learned and how much I know, it also amazes me how much I have yet to learn.
I’d like to pick up like a dozen batteries so I’m good for a while, and there’s some things I don’t understand. First off, 18650s are available through so many various suppliers and they come in 1800 mah, 5000 mah, all different mahs.
I don’t even know what a mah is and frankly don’t care. But I DO need to know if I need to stick to a certain mah so I don’t blow my face off, or is higher may just better and longer lasting?
And I suppose secondly, my hyper vapes nephew told me just to get Ωgrown or Ωlife, whatever those ones are called, because at whatever price they are the best.
And where to buy? Cheap Chinese?
Thoughts?

Here is Battery Mooch’s youtube: https://www.youtube.com/channel/UCePHh3NMvu3rW2LFJeOWo-Q
Everything you need to know about vaping batteries. The short version is mah is a number indicating how long a battery will last. Higher the number the longer it will last. Current rating is the “max” current draw the battery is rated for. And of course, like a lot of the vaping industry, batteries are constantly over rated. And yes, the chinese are making inferior look alikes as well as claiming outrageous specifications. Battery Mooch does battery testing and publishes the most reliable specifications available for vapers.

It’s a measure of how long the battery will last (in simplest terms).

The more important question is: what power (wattage/voltage) do you typically vape at?

Second, what’s the MAX power that you will vape at?

@joel’s right @Chef_Johnny, illumn carries legit batteries. I personally only use Samsungs and Sony’s with mostly Sony’s being the majority. Mooch IS the battery God.

I have provided a little more information which might help choosing/evaluating batteries.

Note: mAH is measured from full charge to 2.9 Volts DC battery voltage. My own (and it seems some other) mods do not function well (or at all) when the battery voltage consistently drops below 3.3 VDC (3.4 VDC on my Pico 25, and said to be as high as 3.5 VDC for the comparable SMOK item). Consulting the published spec-sheets (as well as empirical, albeit approximate, observations as to battery life) for my Samsung 25Rs (rated at 2500 mAH) and Samsung 30Qs (rated at 3000 mAH) - when measured at 5 Amperes continuous DC current discharge rate - both battery models cross 3.3 VDC at nearly exactly the same time (and with virtually identical discharge voltage curves prior to that time). As a result, the (actual, useful) battery mAH capacity differences are close to nil (in such mods as listed above). Something to possibly consider to keep the subject of battery current capacity eminently simple and straightforward, not at all unlike falling off a log.

Samsung 25R delivers maximum power at ~10 Amps discharge rate. The 30Q, at somewhat lower current.

Model --------------------------- Discharge Current (Amperes) ------------------ Watt-Hour Capacity —
25R ------------------------------------------ 10 Amps ---------------------------------------- 7.78 --------------
30Q ------------------------------------------ 10 Amps ---------------------------------------- 7.50 --------------
25R ------------------------------------------ 15 Amps ---------------------------------------- 7.02 --------------
30Q ------------------------------------------ 15 Amps ---------------------------------------- 6.30 --------------

I generally run a geekvape legend or similar with regular old mesh coils and never go over 80 watts unless I’m goofing around, my units are always between 48 and 63.

Jeeziz, 24 bucks for ONE battery? Does it whisper sweet nothing’s in your ear?

Sounds like you might be getting up towards 15 Amperes discharge. This Canadian brand Molicel (last time that I checked) was the only battery manufacturer on the planet who is officially OK with people using them for vaping devices. All other brands (and, I read, most if not all the vendors, who cannot make claims for defects) will reject any/all customer claims for defective products - (if) the customer indicates to them that they are used for sinful vaping rituals and such.

This (by “Molicel”) was “The Mooch’s” big winner (in this Fakebook post, with April 2019 re-test post here):

That’s probably going to be for a protected cell- they are typically used in flashlights AND NEVER for vaping.

If you don’t know much about batteries, I’d recommend using this calculator


It asks a couple questions and then suggests the type of batteries that are suitable for you.
The higher the mah’s, the more energy the batteries can hold, so the longer you can vape between recharges (generally speaking, talking about quality batteries). The higher the mah’s, the lower the continuous power output as well (generally speaking). But you’ll be safe with the suggested batteries.
(do not use this calculator for mech mods).

The efficiency of your mod should be in your mod manual. I know for a DNA 250C it’s 98%, but if you don’t know, leave it on 90%.

This is all very useful, thanks!
I’ll have to review all this stuff.
Haven’t heard any (as Raven would say) empirical evidence of any particular battery being a standard.
Maybe ill get 4 expensive ones (not 24 dollars) and see if I notice a difference.
And oh, I kinda knew that Chinese probably isn’t the best idea, well, cheapo Chinese.
I was hoping would just say, “here get these”, and others would agree.
But I’ll do my homework.

You gotta be careful with stuff like this. Some people don’t lock their mods and put it in a pocket… then accidentally fire at max power. Question should be, what is the max power that your mod will fire at (including those accidents)?

Well, here you go, from demi-god Mooch (nice guy). Updated August 23, 2019.
The Molicel P26A - Best All Around 18650 (if that is what you are seeking, anyway):

… especially with the kind of Wattage you are projecting (at least with single battery cell mods). I only draw 2-3 Amps with my mods - so the higher Amps capability is not critical, and I use Samsung 30Qs and 25Rs.

Regarding Molicel P26A:

… if you run your cells down to 3.5V-3.6V (when put on the charger), and wanted a slightly more consistent vape that could run for longer, then the P26A is worth trying. … The datasheet lists the minimum capacity at 2500mAh and typical capacity at 2600mAh. The six P26A’s I tested delivered 2607-2641mAh at 520mA (0.2C) down to 2.5V. This is great consistency and they all easily met their minimum capacity rating. … I am rating this Molicel at 25A continuous with a temperature-limited rating of 35A as long as you stop before the cell reaches 60°C. …

… The P26A is my choice for best all-around 18650, for up to 25A or 75W per cell. The combination of its great performance along with its availability from authorized Molicel vendors makes it the best choice in my opinion for moderate to high power use in any device. We don’t have to worry about getting low grade, counterfeit, or old cells and Molicel is willing to sell to the vaping community. No other battery OEM is openly willing to do that.

Since no vendors imported the molicel that @Raven-Knightly pointed out to my country (cheaper shipping is a win for me), I use a few pairs of samsung 30q and a few of sony vtc6A now, replacing my lg hg2. That A in the name/type of sony batteries makes all the difference, since it means a higher amperage than a sony vtc6.

mah=Millie amp hours it’s how long the battery runs.the higher the mah the lower the amp which means it’s basically a mouth to lung battery.you can use it for other thing but why?:joy: the lower the mah the lower your build can be.sub ohm, pick up some Samsung 20s the blue ones.man you can vape nice and with confidence that the :battery:isn’t going to have a problem.just don’t have any messed up wraps.

This is a reputable seller, above link is for international customers. I get my Samsungs there for less than 3 euro.
