I have a kraken nr-1000 dive light that came with a rechargeable 18650 that only lasted a few charges, but since its not frequently used, its out of warranty. Looking to replace with another rechargeable...thinking maybe something like this molicel would work but not sure if 10A is appropriate. Can't find anything on the light or documentation to indicate. Any thoughts or suggestions? Thanks.
What battery amp?

That battery should be fine, but check the length of the battery that came with the flashlight. Since the included battery has a USB charging port on the battery itself, it will likely be at least 70mm long. Also, the flashlight will only use the amperage it needs up to the battery cutoff. I cannot find any information on what LED that flashlight is using. Typically, 1000 lumens in a modern LED flashlight will be around 6A or less.
BUT, that can vary (up or down) based on the lumens per watt of the LED. If it's using an old cheap LED that only does about 60 lumens per watt, then it would draw closer to 9A, and if it's really inefficient at say 40 lumens per watt, then you would need about 13.5A to hit that 1000 lumens.
