Hi all, i'm new here because i'm looking for help and hints for my 18650
I got 18650 because of flashlight and lasers.

The 1st ultrafire was hidden under another ultrafire brand :FACEPALM:
The one with "TZ 18650-1331-12" mean something good ?
To the right the one "nude" is the same as the one below.
So for the cheaps ones here, can i use it ?

The Sanyo come from here: Genuine SANYO 18650 2600mAh Rechargeable Battery with Protection Board - Red (Pair) - Free Shipping - DealExtreme

The Sony ? come from HP portable batterie only 3 because the other ones was 0V, this 3 one was fully charged to 4,18 - 4,20V without being hot.

The last one come from a free mini charger, i don't know if i can safely use it !

My charger is a Nitecore i4.
Thanks for your held and advice !

First of all, Ultrafire batteries are inferior and should only be used as a last resort. Store them in plastic containers or they may cause damage if they explode.
With that said, let's have a go at these...

Top left battery looks like an entirely fake cell. Meaning that on the inside it is probably not an 18650 but rather a tiny battery and the rest flour or sand.
Next from left looks like a 'legitimate' Ultrafire battery, capacity is fake but not too bad. It is still probably a true 18650 cell.
Next red one looks like another FAKE. Most likely counterfeit battery, same as 1st.
Your TZ 18650 is protected which means it is very unlikely that it will explode. Not the best battery but it will not injure you.
Your 'nude' battery, top right, should be thrown out immediately. Otherwise if it comes into contact with metal it may have an uncontrolled short = explode.
Middle right, red battery, looks to be another legitimate Ultrafire. Fake capacity but still an 18650 cell. Should be 1000-2000mAh.

Next row.

CTD18650 looks to be a good cell, no danger.
Sanyo of course, good protected cell.
Those green batteries do seem to be Sony, they are pretty safe cells.

:beer:

Thanks for your answer.
Sorry my english is not very good, so if i understand it's something like that ?

For the batteries who are the same you said "Next red one looks like another FAKE. Most likely counterfeit battery, same as 1st."
If i remove the plastic it's the same as the TZ 18650 but the problem is the protection cirtcuit isn't covered now so maybe it's dangereous, so i dont know if i can continu to use this one.

Yes that battery will be safe with the protection circuit uncovered.

Even for the metal bar on the side ? Thanks

Which metal bar? Are you talking about a laser host? If you're still afraid you can always cover the protection circuit with a bit of tape.

This bar on my battery, not protected now.

If you took it out of the plastic casing you should probably throw it away like the other exposed battery. It will not be useful like that.

Ok thanks too bad, they look likes just good batteries. Sorry for late.
