U-Charge Power System
™
Kilowatts of safe Lithium-ion power.
For the first time in the industry, Valence Technology, Inc. delivers Lithium-ion
technology in universal Lead-acid sizes for large format applications. The
U-Charge™ Power System is a family of 12-volt Lithium-ion energy storage
systems that offers twice the run-time and a significantly lower total cost of
ownership than standard Lead-acid deep cycle applications.
Traditionally, the motive industry has relied on Lead-acid batteries to power
devices such as wheelchairs, scooters, electric bicycles, marine vehicles
and more because Lead-acid was the only choice. The U-Charge Power System
Family is changing that! Today, the U-Charge system is conveniently packaged
in standard Lead-acid sizes ideally suited for a variety of motive applications.
Utilizing Saphion® Lithium-ion technology, the U-Charge system combines
superior performance with safety features making it the high-end alternative
to Lead-acid deep cycle battery solutions.
The U-Charge system is the choice over Lead-acid
systems For years, the industry has accepted the many hazards of Leadacid batteries, including the explosive gases generated during charging, the
toxic nature of lead inside the battery which creates disposal issues, and the
corrosive sulfuric acid electrolyte. Now, with the U-Charge system’s patented
Saphion Lithium-ion technology and massive energy potential, there is a direct
replacement for traditional Lead-acid solutions: A replacement that is longer
lasting, lighter and safer than Lead-acid battery systems.
Lower overall cost of ownership The U-Charge system requires
little to no maintenance, delivers greater energy density, better reliability and
more safety at a lower cost of ownership than Lead-acid batteries. How is
this possible? Saphion Lithium-ion technology makes it possible.
Saphion technology provides long run-time, exceptional cycle life, and superior
shelf life. Saphion technology combines the power of Lithium-ion with the
safety of phosphates making it a superior alternative to traditional Lead-acid.

Saphion technology utilizes a phosphate-based cathode material in place
of the metal-oxide materials typically used in Lithium-ion solutions. Saphion
technology is chemically and thermally stable, enabling the creation of safe,
large format battery solutions like the U-Charge system. And, it offers the
energy density advantages of Lithium-ion technology. The U-Charge system:
A high quality product of considerable value.
