18650 battery at 13 watts

[bgoracy]

Hello All,

Does anyone know which 18650 battery would last the longest when vaping at 13 watts? I have listed some below but any not listed recommendations are welcome as well.
(PS please don't respond with battery safety information or suggestions for me to look at mooch ratings)
Also, does anyone know if the vendors in the last 3 below links are reliable?

Thanks!

Well, the one with the highest mAh rating, but then the usage variables get involved. There is a battery sub-forum. Search within that forum.

Dude - "(PS please don't respond with battery safety information or suggestions for me to look at mooch ratings)" Guess you didn't see that?

Any 18650's with more than 3500mah that are not crap batteries lying about it?

Yes I did.
Good luck trying to fit a protected battery into your mod.

Hi, where can I find that info? Didn't even know batteries were protected and unprotected...

 

[stols001]

Well, if YOU are unwilling to look at Mooch's blog and then tell us not to reference it I am going to recommend that you buy 500 of the protected batteries and "vape" with them. They will be best for not BLOWING you up so GO FOR IT I say even if you have to scavenge off Ebay and well, enjoy your protected, counterfeit rewrapped efests. But you won't go BOOM.

Come on now. The only rational reason to this post is like, you would like us to give you the "least dangerous" battery that is still dangerous.

So there you go. Have fun.

I'm sorry but JESUS.

That link to Orbtronic battery (last one), if you scroll down it says:

You can't use a protected battery at 13 watts? My evic primo shows about 2.7amps when firing. I would never buy batteries from any vendor that is not recommended, hence my question above.

Protected batteries use a more volatile chemistry and many are too long due to the "protection" circuit.
@Mooch can explain better than I.

 

[Punk In Drublic]

Any chemistry can be used. A protected battery has a circuit or fuse attached to the positive end of the cell. This increases the length of the cell which makes fitting into a vape device problematic. The circuit or fuse will increase the internal resistance, therefore decrease the watt hours of the battery. They are also limited to 10 amps or less.

@bgoracy – on the topic of batteries it is difficult to NOT reference Mooch. This is not just due to battery safety but due to his years of experience, skill sets and testing methodology. If you care to read his blogs, and watch his videos you will learn that mAh is not the only factor when it comes to battery life. mAh is measured at <1 amp down to 2.5 volts. We do not vape at <1amp and down to 2.5 volts. Watt Hours can be measured at any current draw and down to any terminating voltage. It also displays the amount of energy a battery may possess for a specific duration. Two 3000 mAh batteries could have vastly different Watt Hours. In fact, a lower mAh batter could employ a higher watt hour over a higher mAh battery for a specific current draw.

Also...the 2.7 amps you are reading on your Primo screen is coil current, not battery current. With a regulated device the battery does not see the coil resistance, it only sees what the regulated circuit is requesting in terms of wattage.

What the eVic Primo shows on the screen is the current draw on the coil from the chip. This has absolutely nothing to do with the current draw from the battery.

PiD beat me too it.

Nothing personal, but if you don't want advise from mooch, who is by far the most respected battery expert in these parts, why come here asking for advise?

Ok - Thanks all, I was just looking for a recommendation for the longest lasting 18650 using 13 watts and a 1.6ohm coil. I have never actually used a protected battery and probably shouldn't have linked to them as they probably wouldn't fit as puffon mentions. What I didn't want was a long technical discussion about battery chemistry and safety, I just wanted some actual users of actual batteries in their mods to let me know which 18650 seems to last the longest at around 13 watts. Sorry for any confusion.

 

[englishmick]

I use HG2 LG batteries. Mostly 1.3ohm coils at 12 W. They last quite a long time. I haven't measured how long they last or compared how long different batteries would last. It wouldn't be a big deal to me if I found out a different battery lasted a few hours more. I picked them because Mooch recommended them as being safe and reliable. Seriously, if you want that kind of information you need to go to someone who has actually done those measurements, and you know who that is.

 

[Punk In Drublic]

Difficult to determine what is the best battery for every compatible battery would have to be tested and compared under your vaping conditions. We do not have such luxuries.

The Sanyo you have chosen is an excellent candidate – won’t say it is the best but will suit you well.

I've just read this guide: (9) Battery Basics for Mods; the Ultimate Battery Guide | E-Cigarette Forum (how do you tag specific parts of this forum by the way?)
It really explained a lot, I wish I saw it before. Seems I was quite lucky as I had no idea what I was doing and somehow managed to buy the right batteries for my mod (smoke majesty luxe+ tvf12 prince tank)- the brown LG HG2. But having read it, I probably should have gone for lower mah and higher amp batteries.

These protected batteries: the comments below the guide state that protected battery technology is outdated, and these comments are from 2013! I don't know why anyone would consider buying something that was outdated 7 years ago...

forget the question about links, i see it converts the link automatically pretty new to this forum lol

Sorry, but have to agree... I often do low draw (amps) MTL but still look at Mooch's advice... also do RTAs with (slightly more draw (amps) Mooch's info is so good... why not look into it... or don't, doesn't matter to me what you do.
