There are many battery chemistries to choose from, and depending on your application one or more chemistries will have advantages to you over the others. The following is a brief overview of the chemistries Ultralife designs with.

Lithium-Manganese Dioxide: Our Lithium-Manganese Dioxide cells and batteries allow full rated capability at start-up (no voltage delay) and are significantly safer than any comparable high rate system. Cells have a 10-year shelf life and are available in various standard sizes.

Lithium ION: Our Lithium-ION prismatic (rectangular) cells offer high energy density, high capacity and long cycle life in the most common, lightweight sizes - with no memory effect. These cells, which operate over a wide temperature range, are ideal for many portable electronic devices - including rugged military equipment.

Lithium Polymer: Ultralife Polymer® rechargeable batteries combine high-energy chemistry with state-of-the-art polymer technology. Every battery component is solid - there are no liquids that need to be contained by bulky, heavy cell housings. The result is a powerful, safer, thin and lightweight rechargeable battery with a wide operating temperature range and no memory effect.

The Ultralife Polymer cell operates at an average voltage of 3.7 V, desirable for single-cell applications like digital cameras and other portable electronics. Cells can be configured in series or parallel to achieve optimum voltage, capacity, and rate capability for specific applications.
