Sanyo Lithium ion Higher energy density, Higher Voltage

Smaller, lighter, more powerful

Meeting today’s needs for a compact, portable, and robust source of energy.

Devices designed to make our lives easier are being developed at an increasingly rapid pace. With the multimedia age

dawning, the market is becoming more diversified with such innovations as lightweight, compact video equipment,

personal computers, and data-processing equipments. Such devices have created a need for high-quality, reliable power

sources that provide excellent functionality.

Sanyo now introduces a series of lithium-ion batteries offering a higher energy density and three times the voltage of Nickel-Cadmium (Ni-Cd) and Nickel-Metal-Hydride (Ni-MH) batteries. What’s more, lithium-ion batteries are composed

of materials that are both safer and less damaging to the environment.

Smaller, lighter, and more powerful. Sanyo introduces the new generation battery for the forth-coming multimedia age.
