Will better 18650 batteries make my laser pointer stronger?

[DanTheMan69420]

I recently got a high power laser pointer on eBay from China and everything works great and burns stuff but the 18650 batteries it came with feel cheap and claims it’s 4800mAh which is obviously a lie. So my question is would buying higher quality batteries from a reputable manufacturer make the laser pointer stronger? Thanks in advance

Not in a lower power pointer like that. Higher mAh batteries will only last longer between charges.

It’s around 500mw

Yeah, because laser diodes are current regulated you should only get longer periods between charges.

*if* your laser could draw more current then those batteries could supply, then yes better batteries with a higher current output could increase its output power. This is almost certainly not the case though. I would still highly recommend getting good quality batteries though, those cheap trustfire, ultrafire, whatever-fire batteries have a bit of a record for actually causing fires. Handy tip, if you have any vape stores nearby, most of them sell 18650 cells for use in vaping devices, but they'd work excellently in a laser too. LG, Samsung, and EFest are whats available around where I live, typically they go for 8-12$ per battery. Oh, and those stores probably also sell decent quality chargers too.

Edit:
I would also look into some laser safety glasses from a reputable source, the glasses included in a lot of lasers off places like ebay can be severely inadequate. Protect your eyes!
