Any battery I've ever heard about with the word "fire" in its name are low quality with reduced capacity for run time.

Not normally, unless the laser is poorly designed without a constant current regulator. However, if the battery you are using has too low of a voltage for the regular to produce enough current to the diode, then yes, it could.

A few days ago, I used a laser and saw that the light of laser was too much, but after a few seconds, the light decreased.....for this i thinked if i buy new battery can back to that light And be fixed (sorry bad en).....Why did it happen and what do you think is the reason? battery or laser?

Hard to say, maybe someone without a tin hat on their head can answer.

Hi,
If the beam dimmed down after you turned it on it can be a few things . The driver might be out of regulation being a cheap version . Or your batteries are of poor quality and not delivering the correct Voltage to operate the driver.
Or the diode is failing .. Its hard to say with out knowing what laser it is also.

Hi,
Samsung, Sanyo, Panasonic , Efest and AW are all great batteries . Please dont use Trust fire, Ultra Fire and as Alaskan said anything with the word Fire in it. They are dangerous and poorly manufactured batteries. thats why they are cheap by the dozen. Buying cheap batteries is a recipe for disaster..

Any idea where I could get cheap 16340 LiIons without the word "fire" in them. All the decent ones I've seen cost like $10 for a single battery... ideally I'd need something in the $3-5 range

Beware, find a reputable seller, there are knock-off unauthentic copies.

Strongly suggest moving this thread to "Drivers, Test-load, Power Supply, & Batteries" sub-forum

I use those VapCell 16340s from liionwholesale that Encap linked. They're one of the only ones that are unprotected. Statistically speaking, at 800mAh and 7A it's one of the best. Performance wise, I've found them to be all around pretty solid.

Never would've thought to look at vape batteries, I'll give em a shot!

Edit: ... after COVID dies down, the shipping's still a bit steep for me and I have an UltraFire source near me anyways (I could just buy new ones if mine degrade fast)
