Why only button top? Batteries are not manufactured that way. I know the answer and despite I can sort of accept it, it is not of my liking.
If anything a wide button top is better, providing extra contact surface.

Cheers :-)

:+1: or a Raised Flat Top like the VTC5A…

not for me

my lights with physical reverse polarity protection rings, (example Jetbeam RRT-01) dont make contact with flat tops and wide button tops.

Why dont you want to use button top?.. They work in everything, unlike flat and wide tops…

Here are the reasons behind button tops:

  • Original equipment manufacturer (OEM) concealing.
  • Lack of reverse polarity protection in devices.

I didn't say I wouldn't use button tops. I do not support the reasons behind, though.

Cheers ^:)

I have an envelope chock-full of Murata VTC5A cells, thanks for reminding me.

They're plain (not raised) flat tops without a doubt, just checked.

Thanks

Could you help me?

Why did all my pictures disappear?

I quoted links to pictures that could be displayed before.

Now it’s gone.

In what post?

Thanks,
We are very pleased with your comments.

will sell battery in Ali soon :slight_smile:

When I look at the source of the first post - there are image links there.
Copying a link and opening in another tab shows me image - so this is working.
However when I reload the BLF site and look at network requests - my browser tries to load the images but your server refuses to give them with error “403 Forbidden”.
I don’t know maybe your web admin added some embedding “protection”?
Anyway the issue seems to be with your image host.

Thank you very much. I uploaded photos on a different website.

Now it’s all right.

Looking at the below discharge graph, this 16340 has more capacity at 5A than at 2A? Something doesn’t sound right.

Anyway, I ordered a few from illumn to try.

The fact we cannot understand something does not make it impossible. Such phenomena can happen. For example:

Source: HKJ's comparator and review of Samsung ICR18650-30B 3000mAh (Green) @ lygte-info.dk.

In general, I’d just ignore mAh readings. Wh is a much better indicator of capacity.

My 16340 800mAh Vapcells still haven’t arrived even though I ordered them on April 4th. Once they were returned by customs and sent again.

Capacity is the whole are below the line in this graph not just the finishing point.

The Vapcell 16340’s I tested at 3 amps seem to follow the supplied graphs pretty well. It’s the best 16340 I have tested.

I was referring to the actual capacity values listed in the table directly below the graph.

Sometimes you get higher capacity at higher discharge rate because the battery “doesn’t get discharged completely”. This is why energy is a much precise way to measure the real capacity because it can be translated directly into lumens/hours.
