18650 battery and mah ratings

[jersey girl]

Hi,

I have been using an imr 18650 battery 35a , 3.7 v high drain, with a 2500 mah rating. Is it ok to use the same battery with a 3500 mah rating?

I am using a sigelei 40W box mod. I only vape at 7.9W. with a 2.1 ohm coil.

It is time for me to replace my current batteries and I noticed the higher mah is available. I believe the mah rating is how long the battery holds its charge. but wanted to check with on here before I ordered and used the higher mah battery. Always worried about safety.

First thing is make sure you buy from a trusted source. Secondly many battery manufacturers list their batteries with exaggerated mah. Lg, Sony, and Samsung are all listed with the correct mah and the batteries with the highest mah that is safe for you to use is the Samsung 30q, the Sony vtc6, and the Lg hg2. So as long as you buy them from a reputable vendor you will get legit cells and the three listed are all 3000mah which is the most mah you can get with a 20amp ratings which is safe for your setup.

Counterfeit batteries often exaggerate both amps and mAh. 20 amp, 3000 mAh is the best. I would be skeptical of anything claiming more.

Go with one of the recommended brand, from a reputable vendor.

another thing to mention is Mooch who is a member of this forum. He tests all these batteries and is his reviews of the cells is gospel. He isn't paid by the battery manufacturers so he doesn't have any nefarious intentions. Just quality testing of the cells we use so if you search his name you can find his reviews and I suggest you follow his threads because when new batteries come out you can get the scoop on their performance and reliability.

Yea after Mooch's extensive testing his conclusion was that there isn't an 18650 battery made that has over 3000mah and over a 20 amp continuous output. He has tested basically every battery you'll come across also. But you should read his reviews because I'm probably not explaining exactly correct. I am in no way Associated with Mooch, Mooch inc., or any of his affiliates.

The thing you want to be a bit careful about (aside from buying good batteries) is the amperage you're pulling from the battery. At 7.9 Watts (which is an oddly specific number- don't you change that at least a bit for different juice, etc?) you're not likely to stress a good battery much, and you could likely get away with a lesser battery (with maybe more mAh,) especially in a regulated mod, but... honestly you can't be going through batteries that quickly, so I'd think that you'd do best to stick with good vaping batteries, which tend to top out at a claimed 3000 mAh.

I'd also steer clear of batteries that claim a lot more than they deliver- that's a bad sign. With your usage you're actually more likely to have battery issues on the charger than while you're using your batteries in a decent regulated mod, I think. If you want a bit more capacity the LG HG2s are perfectly good batteries that claim to be 3000 mAh (a bit less in my experience, but close enough.) Samsung and Sony also make good batteries in this range. Just make sure to buy from a reputable source, as there are a lot of counterfeits out there.

I ended up taking a snapshot of Mooch's battery list telling us what cell (with pic) and what the manufacture rating is and what his rating is. With his background with these cells and his research I'm going off what he says. Here is a pic of that snapshot incase anyone on here wants to take a snapshot so they always have it.

I'm just going to expand on what you said. Noobies may not know what the "reputable" sources are for good authentic cells so I'm just going to add that 2 of the ones a lot of people on here order from is http://Liionwholesale.com and http://Illumn.com. The OP will find these 2 links to websites of the vendors that have authentication and the cheapest prices.

1) 35amps <- This is a dangerous rating, it is not the Continuous Discharge Rating being listed, but the Pulse Discharge rating, the difference between CDR and PDR is CDR is what the battery can sustain the whole discharge from fresh 4.2v charge down to 3.0v, PDR there is no set variables of what is a considered a max pulse time, it could be anywhere between 1/2 a second to 2 seconds, after that the battery has to shift down to CDR or overheat and potentially vent. The big 4 main battery manufacturers (LG, Sony, Samsung, Panasonic/Sanyo) on their authentic A Bin batteries they sell never list an Amp rating on their casing or insulator wrapping, just model number, a serial or batch number, and the nominal voltage rating 3.7v with the Mah rating. Most other battery "Sudo-manufacturers" like Efest, MXJO, AWT, Eizfan, Beizen, etc buy up the B and C bin discards the big 4 won't put their name on and sell as authentics, re-wrap with the Sudo label with the PDR amp rating. You really want to trust a battery that didn't pass muster to begin with near your face, especially when false advertised as a 35 or 40amp battery, not knowing what actual cell is underneath that insulator wrapper????

2) Best 3 batteries for your vaping application would be the Samsung 30Q (3000mah 20amp CDR light purple/lavender), Sony VTC6 (3000mah 15amp CDR manufacturer spec, independent tested 19amp CDR pine green), or the LG HG2 (3000mah 20amp CDR manufacturer spec, independent tested 18amp CDR chocolate brown) those are the only 3 with the highest mah and safest CDR on the market atm.

3) If you live in the US/Mexico/Canada try getting authentic batteries from these vendors

I respectfully disagree.
Go with a battery that can cope with the maximum power of your regulated mod.
That way if the regulation fails the battery will hold up.
Also there is the possibility of accidentally setting mod to max, or if you hand the mod to some 'drunken noob' in the pub and they start playing with the settings there will be no nasty surprises.

Thank you for all the info. I will order from your recommendations.

Good Deal.

And just a follow up on your mAh question.

Basically, the mAh of a Battery is how much Capacity the Battery has. Think of it like the Gas Tank in your car. If you put a Bigger Gas Tank in your car, it doesn't make your car run any Faster or any Better. It just let's you car run Longer before you have to Fill it again.

Really great analogy that noobs will be able to understand!

Thank you for your answer. If it was the same battery specs and manufacturer, I wasn't sure if increasing the mah's would make any difference other then how long it lasts between charges. So I will be fine ordering my battery is the 3000 mah rather then the 2500 mah. Good to know.

It may seem strange with all the sub ohm and high watt devices on the market. But I love my 30 watt box mod and only vape at 7.9W or 4.2V. No I never change that and been using the same brand/flavor juice for 6 years.
Hardware of course has changed over that time frame. It took a long time to fine what I really like so I stick with it.

Not strange at all. There's no reason you can't have a vape like that as long as you're satisfied. I think there are lots of folks who not only started out low watt and have stayed with it over the years, while some went for the subohm cloud thing. Nothing wrong with either as long as you're happy and not smoking. Congrats on 6 years too!

I didn't think it strange because of the low watts. I mix it up, but a lot of my vaping is pretty low watts, though not quite that low. I switch juices a lot though, so I adjust the watts a fair bit- I'll even adjust a bit for the same juice depending on how it's tasting to me that say. I just thought the 7.9 was very specific . But if you vape the same juice in the same equipment it makes sense.

Ah, I wouldn't disagree with you there, and we might differ in phrasing more than anything else. I agree that even if you'd be theoretically safe with a lesser battery you should still use a good one.

 

[Oomee]

Yes, I was referring to the maximum current (not mAh spec).
A mod that has the capability for high power will have PTC's/fuses that will allow high current to flow. They will only interrupt current above the spec of the device.
So even if the mosfet goes short circuit the PTC/fuse will only offer protection above that limit.
You need a battery at that level of Amps or risk over-current a lesser battery and that is very dangerous to do.

 

[jersey girl]

Even tho I could get away with a lessor battery, because of the watts I vape at. I always use a battery that is recommended for my mod.

I use to be a fan of samsung, but after all their phone issues with batteries, I don't think I would purchase that brand.
