Valence to end sales of small back-up battery systems

For Valence Technology, bigger is better.

The Austin rechargeable-battery maker said today it will phase out its N-Charge products, which are typically used as back-up power for notebook computers and other electronics.

Valence said it will cut off sales of one N-Charge model immediately and stop selling the other July 31. It will continue to support the 12-month warranty on the systems and provide tech support, the company said.

For the past four years, Valence has shifted its resources and energy away from the small N-Charge models in favor of larger battery systems made to power vehicles, boats, Segway scooters and cell phone towers.

Valence’s batteries are made of a lithium-phosphate chemistry that is more stable than the lithium-ion batteries found in most notebook computers and many other consumer electronics. That allows the company to make bigger systems for larger applications without the added risk that can arise with less-stable chemistries.
