Got this laser for my bro and I

https://m.dhgate.com/product/most-powerful-burning-blue-laser-torch-445nm/420675733.html

And there seem to be many alike it but the battery model is not specified. Anyone know how I can decipher from the laser what the exact battery model name is ? My stores might sell em otherwise a link to a site with the 2 batteries it needs would be appreciated.. Comes with the charger tho

The laser in the first photo looks like it takes two 16340 batteries. You may be able to squeeze in two 18350s at a higher rating capacity. There are several cheap lasers shown on the page you linked and one of the last ones takes a single 18650 battery. That is the best I can do for you without more information.

Woah great deduction skills, thanks, you listed em in order of resemblance to the photo. Are you sure those last 2 you listed are safe to try and won't fry the circuits ?

Also, any good site that would free ship those to Canada with potential for returns lol ?

I recently purchased two 16340 batteries for a new build, but the batteries didn't test well being rated at 700 mAh and testing below 600 mAh with a dynamic internal resistance of ~160 mOhms. They cost me $6.99 and came from California, but I wouldn't recommend them. I buy all my 18650 batteries from Liionwholesale.com. They have a $10.00 shipping charge so it is best to buy all you might think you will need. I got some great deals on four 18650s for a total cost of $30.00 with two measuring more than 3500 mAh and the other two better than 2500 mAh though they were rated at 3500 mAh 2100 mAh.

Yeah not fair that they can boast false mAh's as folk do with wattage here all the time. Burninglaser.com claims 1200mAh which isn't even worthy of lying about so I shall perhaps try them

Any place claiming a 1200 mAh capacity for 16340s is just lying. The highest I've seen is 700 mAh. If they claim more than that, they aren't likely to even do 700 mAh. Don't buy any batteries with the name fire in it. They are all trash. Crapfire, Trustfire, XXXfire just pass on them.
