Go to http://www.illumn.com/ or https://www.mtnelectronics.com/index.php and pick and choose from there. Those cells you have are NOT 5000mAh and anything you buy from either of these sites will perform better. You can trust the mAh ratings of the cells advertised at these two sites.

Others can suggest trustworthy Chinese suppliers that ship to you.

My gratitude to those who are willing and able to help others (in whatever way you can)! Being human is more than just existing for yourself. Smile

Yes, and likely very poor quality cells. If my life depended on it (and depending on your dives it might), I certainly wouldn’t use those cells. Get some quality name-brand cells from a trustworthy supplier. And while you’re at it, make sure your light is legit too.

You will want to buy Panasonic, Sony, Sanyo, Samsung, LG batteries.

These Sanyos have the highest capacity available (real 3500mAh):

You will notice they never call them by the brand names though.
Those brands make those cells for battery packs and they don’t want you to use them outside a pack (like in flashlights).
For safety and legal reasons they prohibit or do not endorse selling them for use outside battery packs.
They should be handled with extra care, because there’s a lot of energy in those things.
