A battery for my Catapult mini?

Back in February, I got a ThruNite Catapult mini Amazon. With very little use, it's 18350 died on my. The return window closed on me and now I have to get a couple batteries.

The 18350 is branded a ThruNite product. Is this not a top tier brand or did I get a defective product? From the get-go the runtime was fairly snd it charged very quickly, two red flags I should have noticed.

So is there a particular brand I should consider? I assume the 18350 is the highest capacity battery that will fit in the Catapult mini.
