People generally recommend samsung 25rs, lg he2/he3, and there is a panasonic or 2 also. Most of them are 20amp though. illumn.com have been getting the sony vtc 3 back in stock regularly though. I guess sony moved manufacturing plants around...
To risk stating the obvious check continuous amp load - ignore 'pulse' and other dubious stats and stick with sony/samsung/lg/panasonic. Anything with fire or fest in the name is just a rewrap of someone elses they didn't feel selling as their own

Samsung 25R, LG HE2 and HE4 when it comes down to 20amp CDR, with the Samsung 25R being a popular strong runner.
Sony VTC3 and VTC4, as well as the LG HB6 are your 30amp CDR choices at the moment
MXJO
Imren
Efest Purple
and several others are out there with Amp Specs of 35 on up to 40amp printed on the battery wrapper, sadly these are most times as stated above re-wrap of another 20amp CDR battery already listed

These will be your best places to look for authentic batteries.

It depends on what your coil resistances are (if using a mechanical mod) or what power levels you vape at (if using a regulated mod). As mentioned above, the VTC5 has been labeled a 30A battery by many people but it's really only 20A. Not sure then if you need a replacement battery that can handle 20A or 30A.
You've gotten some great recommendations. Mine are...
Up to 20A = LG HG2
Around 20A = Samsung 25R
Over 20A, up to 30A = Sony VTC4
30A and higher = LG HB6
I use the eFest IMR18650 2800mah 3.7v 35A. Great batteries never had a problem with them.
Just remember and be careful, that 35amp label is a Pulse Discharge Rating, not a Sustainable Continuous Discharge Rating, which the CDR on those are 20amp CDR.
It should be take into consideration that no cell manufacturer have ever rated their batteries for a use over 20A . Efest wrap these batteries and rate them for ''80 Amps pulse''. whether or not all these re-rated specs (talking for every brand right here) are real is up to faith really so they should be taken with a grain of salt. I personnaly used Efests in mech mods for over a year and a half and I'm am well satisfied of their. I had issues with autofiring on my stingray and I must say I am thoroughly impressed how they still lives after the stress they have been put into.
That said I now use He4s just for the extra safety in mind. Anyway the way I understand it, You really have to build below the .2 ohm in order to pull over the 20Amps. I just do not recommend to go below .2 ohm exeption made for temp resistance coils. Going below .3 ohms to me is the realm of dry hits and you don't really get much more flavor/vapor from your investment.I'm pretty sure all reputed brand of batteries would do just as nicely in pair inside todays regulated devices. Might be wrong on 200 watts mods though.
There is no such thing as a 35a 18650 battery! But there are more than enough vendors/suppliers that would like you to believe that there are.
They could print their wrappers to say that they're 100 amp batteries, but the cell would still be whatever is under their wrapper.
add:
You might find it interesting that Sony does not state the CDR of their batteries. Instead they state that the specifications of VTC cells are those specified by the company that they are being produced for.

Just curious but how do you know that there is no such thing? eFest is a highly reputable company and don't know why they would intentionally over rate there product.
Several people here and on other forums test, extensively claims of what a battery is capable of.
Examples of such testing from @Mooch 's blogs here ->

eFest does not make batteries .... they rewrap batteries.
eFest has ALWAYS over rated their batteries. They have ALWAYS been the biggest offender!
The trick with eFest batteries is to identify what cell is actually under their wrappers. You will fine that in many cases they are just using "B Bin" cells of quality batteries.
ie: Samsung or LG and the like.
That blog post shows no legitimate factual information or testing but thanks for the heads up.
I do own a 2500mah 35A battery from efest. It is however a rewrapped battery (likely LG HE2). Good thing the rewrapped battery is actually pretty good so I have no complains.
It does pay off to research on your efest batteries before getting them though!

I assure you, the information that is there is factual. I have been testing cells for over 20 years and Efest is one of the worst offenders when it comes to exaggerated ratings claims. Did you scroll down that link? That blog does show testing, for almost 40 batteries, including two Efests.

Efest 35A 2800mAh 18650 Bench Test Results...a 20A/2300mAh battery | E-Cigarette Forum
The 38A/2100mAh cell is really only 20A. At 30A its temperature had risen to almost 100°C, an extraordinarily high temperature and clear evidence that the rating is not 38A. In addition, at only 30A, the voltage quickly drops to less than 3.1V, rendering it essentially useless at 30A.
The 35A/2800mAh is also really just a 20A cell. At 25A its temperature was near 100°C. At 25A its voltage quickly dropped below 3.2V, also rendering it essentially useless for vaping.
Check the discharge tests of any battery reviewer on the Web and you will find similar results. I don't think you will find an Efest cell that lived up to it ratings.

Efest has one of the worst reputations in the industry. Why would they overrate a battery? Simple, it sells more batteries. If pressed on this issue they can just say, "Oh, that's the pulse rating", which is a useless spec and allows them to print anything on the label they want.
They don't rewrap terrible batteries from what I can see. But, they must be thinking that putting the continuous current rating on the label wouldn't sell batteries. Not when the equivalent one, from the companies that actually make the battery; Panasonic, Sony, LG, and Samsung, can be bought at a lower price,
