I've used their Tenergy brand Li-Ion, Li-Poly, NiMH and Alkaline cells with very good results. Some were used for prototypes and small run projects, some for larger volume (1000-5000 pc.) production use. Overall, I've found their cells meet or exceed their specifications. I was surprised at their Alkaline cells -- virtually identical performance to Energizer or Duracell at about half the price. I have a couple customers that are using the Tenergy Alkalines in production and have had no problems. I designed a medical device that uses a AA size Li-Ion cylindrical cell that has performed flawlessly for about 3 years now. I'm about ready to design that same cell into another product.
