Need help : problem with a TENERGY 18650 battery

It's about a new TENERGY 18650.
A few days ago I have tested in a TIABLO A8 to see the runtime. All was OK, I got even a better runtime than with a AW 18650 !!??

After recharging the battery, I have tried it in a LUMAPOWER M1 .
Surprise : the light flickered once and that's it...
I have tried it in the TIABLO A8 : same result , one flickering and no light coming...
I checked the lights mentioned with an AW 18650 and they are working flawlessly.

The TENERGY 18650 is charged but it doesn't want to work anymore
What could be the explanation ? Just one from a bad batch ?

Could it be the current draw was too high and it tripped the protection circuit?

It would have only tripped the protection circuit if the circuit was either flawed, or the load was over 1.5C or ~4amps.

Both the Tiablo A8 and Lumapower M1 are Q5 lights that are 1A max. That should be no where near the protection circuit limits.

Tenergy stands behind their cells with a 6 month warranty. I'd contact them.

I have tried this AW 18650 in my 3-rd 18650 light : JETBEAM PRO IBS . It doesn't work with this either !
Thanks for the tips Jason. I didn't know that TENERGY is an american company and they have a warranty policy. Just send them an e-mail.I will see what theyt will do !
