LITHIUM - Niobium Lithium Rechargeable

The Niobium Lithium Rechargeable batteries have been added to Panasonic's existing line-up of rechargeable coin batteries for memory back-up. The desirable feature of the NBL is to maintain a higher memory capacity at a lower voltage. This makes it ideal for applications using the newer technology low voltage IC's such as cell phones.

Features:

Excellent at withstanding overdischarge and overcharge
Low self-discharge rate
Maintains higher capacity at lower voltages
Ideal for new technology using low voltage IC's
Super compact design for back up applications

Applications:

Power source for backing up memory data in:
Mobile telephones
Memory cards
Pagers
Other small-size communications devices
