What is the best high capacity 18650 battery?

Of course you'll never feel that 100mAh in real life. But we can't measure a capacity "in real life" that's why we have standards with guides how to do that:) That's what i'm talkin' about:)

None of these BS manufacturer claim numbers are correct. Go look at a proper test done by HKJ and you will see the true capacity.

The 35E has the most mAh, there is no debate about that.

I will order several batteries end of July for me and my friend also. I just want to get the best value product. From the vote, majority say Sanyo is the best (made in Japan) I don’t know HKJ BS procedure testing, but I rather trust BLF users experience. I am just afraid to get fake Sanyo :expressionless:

Any recommendation for some trusted online Sanyo battery seller? (my friend stay in USA)

thank you

Get them from Liionwholesale:

I would get 4xSamsung 30Qs in high drain light scenarios, since they have lower internal resistance, and can lose less power due to heat, along with 4x NCR18650GA or LG MJ1.

Actuall HKJ is one of the best reviewer at here( and yup, he is “BLF users experience”)

You will not get any better “experience” than info from HKJ.

Here is a link to his site…. poke around & check it out. :wink:

The GA keeps a slighly higher voltage than the 35E at medium currents, like 3A, typical of 1000 lm flashlights. I think the higher voltage and total power would be useful for the buck driver that the M2X-UT seems to have.

Still since both are very close I would buy the cheaper one.

Depends what you want.

NCR18650GA has a slightly higher max amperage than the 35E.

35E, however, has a slightly longer run time at lower outputs (<0.5A and below). They are about the same at 1A.

The MJ1’s are pretty similar but seems to be slightly worse.

LOL

If you had a chance to have sex with Angelina Jolie would you do that or you'd prefer to ask Brad Pitt how she does in the bed?

Having all 4 cells in my hands and a good equipment i preferred to do my own tests at the same time in the same conditions, following the IEC61960-2003 standard rather than just sitting in the sofa and posting others' tests.

HKJ has inspired me a lot and i think not only me but also hundreds or even thousands of others. King regards to him from Russia!

In my opinion the Samsung 30Q (and LG HG2) are better than all of them because they also work when it’s cold outside. They also worksbetter in high-powered flashlights and can be charged more quickly. In addition to all of this they are very cheap. Sony cells are also good, but they usually cost much more.

The runtime of the 35E is higher than the NCR18650GA at ALL currents.
Go to the website to compare them at other loads.

It does have more voltage drop at higher currents like 5A, but that only changes the Wh not the mAh.
The MJ1 is definitely worse.

You guys have forgotten the original posters intent and gone way off on a tangent.

What do you expect? This is a website for Enthusiasts! :smiling_imp: LOL!

I think the OP got what he wanted from this thread anyway. :student: :+1:

I’d still buy which ever was cheaper. 100 mah isn’t gonna make much difference unless your driving a led at 1 ma.
Differences in manufacturing and age could make up such a small difference. Same reason HKJ always test two batteries instead of just one.

I decided to order few of each :smiley: All 3 brands seem to be good quality product, so the best is I try them all :+1:
Thank you for your advise!

You have to love Liion shipping rates to Canada. Minimum $52.51 CAD to ship just four 30Qs lol

In the case of a linear regulator it doesn’t matter (apart from the fact that it may fall out of regulation earlier), but if you have a buck or boost driver then Wh is what you care about. Higher input voltage means less current with DC-DC drivers.

That is crazy money. What gives? Is that the shipper’s fault or is it Canada’s?

I don't know but I've been hoarding batteries from Banggood every time they announce they can ship to Canada again. For Liions shipping price, I could just drive across the border and pick up the batteries myself, go spend some money at Harbor Freight and Burger King and still come back with a few bucks in my pocket!

This was talked about in another thread. Apparently, liionwholesale is strictly obeying shipping rules from USPS, and it basically makes it cost-prohibitive to use them. So, they use UPS, which is

(1) Way more expensive, and

(2) You’re going to get burned with additional brokerage fees and taxes when your order arrives in Canada.

It makes ordering batteries from liionwholesale ridiculously expensive for Canadians. So, forget about buying from them.

Instead, I’ve placed a couple of battery orders from Illumn this year. They will use USPS. It costs $15 shipping, but I think that’s for any order size. You won’t have to pay additional fees and taxes when you get your order, either. Much less expensive than liionwholesale, and they’re genuine batteries and extremely well packaged. (Cells in plastic cases, inside a padded cardboard box, inside a bubble-wrap package.)

Anyway, I know liionwholesale gets a lot of kudos here, but I’m guessing that’s just from US customers. Oh, one other issue I have with them is that they won’t guarantee your order, and make you sign a waiver saying that any losses are your problem. What’s with that? They’re the only retailer I know that does that.
