Why some vendors don't mention Batteries Amp ?

[rzil]

by Ohm law , we also need to know the current so how come for example
Efest IMR 18650 2000mAh Flat Top 3.7V Rechargeable LiMn Battery

they didn't write the amp of it ? I see it in many sites , how do I know if that's what i want ?

 

[Kracker]

why not just go with the Sony's ?

Not so sure that was the Ops question.
Perhaps availability?
Maybe preference?
Got any VTC5 in 18350?

Sorry Op, I'd also like to know why the battery industry does not provide better specifications to the consumer.

Yup I don't get it , Amp is a major issue here , perhaps when they mean it's a standard of 10A who knows?

by the way I'm conflicted between efest and AW

AW IMR 18490 Battery

Efest IMR 18500 1000mah 15amp Flat Top Battery

Both are receiving good user reviews. AW has been around for a long time. Biggest problem with either is avoiding Fakes so only buy from a trusted vender.
Remember - abusing any battery can lead to failure. Know the limits and leave ample head room.
If it is rated for 10 amp don't build to 10 amp draw - 9amp max, but 8amp or less is better.

I had efest 18500, then a buddy gave me an AW 18490 to try in my Provari. Maybe it's a mental thing, but Provari does recommend AW and it simply worked better in my device. It's not that much more expensive, so I replaced my efest with AW.

Most of the batteries we use are not made exclusively for vaping. They are used for other applications, where maximum continuous or pulse draw aren't an issue.

Not Listing Detailed Battery Specs is something that Kinda Ticks Me Off. Especially as a Read More and More Threads/Post from New Vapers who want to go with Lower and Lower Ohms.

I also don't think it would be All that Difficult for a Seller to post on their site a Little Information about Calculating Amps and General Battery Info.

Check this thread for the specs on that battery. It's 10C according to a post there. That would make the maximum safe continuous discharge rate 20A. Calculate that by multiplying the 2000mah rating by 10 (the C rating). The 2000mah rating means that it would last for an hour at a 2 amp continuous discharge rate. Vapers do that intermittently, but it adds up over time and is affected by the recovery rate between vapes.

10 (C rating) * 2 (2000mah)=20 amps

There are several amp ratings with batteries. The most important is probably the C-Rating, which is the safe zone for continuous use. Max ratings are there to keep people from blowing themselves up (if they actually read the specs and abide by them).

Here's a significant test chart that show performance ratings for lots of popular batteries. lMR is noted where applicable. There are charts in that link showing the number of hours at various discharge rates. It's worth a close examination. There's lot of info there if you take the time to understand what the charts are telling us.

The link below is an explanation of what the C-rating means. It's a number that when multiplied by the battery's MAH rating gives you the maximum continuous discharge amperage the battery will safely withstand.

Vape suppliers really have no excuse. The info is out there, and they should know it anyway.

Maybe it's the cynic in me, but I think it's so they can charge more for crappier batteries.

AW IMR 18490 Battery

Efest IMR 18500 1000mah 15amp Flat Top Battery

Until sub-ohm vaping came into being, a battery's amp rating was relatively unimportant. The spec that everyone looked for was capacity or mAh rating, which gave an estimation on how long the battery could be expected to work between charges.

With sub-ohm vaping, the continuous discharge rating in amps has become more important than the mAh rating. Battery manufacturers and vendors have not provided this info voluntarily, although it seems some vendors and manufacturers are beginning to see the importance and adding this info to their spec sheet. Keep in mind that sub-ohm vaping is still just a niche market in the grand scheme of the world's battery market.

While researching for my blog Battery Basics for Mods, I had not found a resource which listed all the high-drain IMR batteries with their mAh and amp ratings, so I set out to make one myself. I quickly found out how difficult it was to find the amp rating for different batteries. Most manufacturers and resellers list the mAh rating on their spec sheet, but finding the amp rating was very hit or miss (mostly a miss). After a month of searching online, I gathered what I believe to be current and accurate battery specs for the most common IMR and IMR hybrid batteries used in vaping.

18490/18500 IMR batteries:

AW 18490 1100mah 16.5 amps

Efest 18490 1100mah 8.8 amps (red)

Efest 18500 1000mAh 15 amps (purple)

* Personally, I'd choose an AW battery over an Efest any day of the week.
