Ultralife isn't just a battery company anymore; it has a new life selling power supply systems for communications equipment. The company continues to design and manufacture rechargeable and non-rechargeable polymer and lithium batteries, which account for more than half of sales. Its newer division provides stationary and portable power systems accounts for about a quarter of sales. Ultralife sells its products around the world to original equipment manufacturers (OEMs), distributors, and retailers. The US accounts for 80% of revenues. The company also sells directly to US and foreign defense departments. Military sales (both directly and indirectly) account for about 65% of Ultralife's revenues.
