Rayovac and Sanyo have formed a strategic relationship with the objective of expanding the presence of rapid-charging batteries in the U.S. $5-billion worldwide rechargeable marketplace. Rayovac Corp., a marketer of rechargeable battery brand in the U.S. and Europe, and Sanyo Mobile Energy Company, an in-house company of Sanyo Electric Co., Ltd. and a leader in rechargeable battery technology, have recently entered into a technology and manufacturing agreement to develop additional applications and markets for the next generation of Rayovac's patented I-C3(R) (In-Cell Charge Control) technology for Nickel Metal Hydride (NiMH) batteries.

"We view our relationship with Sanyo as an exciting and significant development in our ongoing objective to remain at the forefront of rechargeable battery technology," said Rayovac David Jones, chairman and CEO. "By teaming up with Sanyo, an established worldwide technology leader in rechargeables, particularly in the important OEM category, we expect to capitalize on the established strengths of both companies."

Under terms of the agreement, Sanyo's research and development group intends to further refine and develop Rayovac's I-C3 technology, optimizing Sanyo's high-capacity technology and extending it to other applications and battery sizes. Sanyo will also manufacture the new advanced rechargeable batteries for Rayovac and is expected to adapt the technology for Sanyo- branded NiMH batteries in Japanese and other Asian markets.

Rayovac's patented I-C3 technology is said to recharge NiMH batteries in 15 min. The company says the technology offers significant performance and convenience advantages over existing rechargeable and disposable battery systems. This technology transfers control of recharging from the charger to the battery itself. A pressure control mechanism in each battery regulates its charge. Rayovac's I-C3 NiMH can reportedly last up to four times longer than alkaline batteries in digital cameras.
