Panasonic introduces a new line of NiMH cells that are superior to standard NiMH products in applications with low-rate charge at high temperatures. Improvements were made in existing Panasonic NiMH cells to the negative plate alloy and, separator fiber density. A new electrolyte composition was achieved to improve performance. Superior long-life characteristics can be achieved when combined with appropriate intermittent charge control circuitry. The intermittent charge consumes 1/3 th the electricity compared to trickle charge and more than doubles the expected life of the NiMH cells compared to NiCd cells that have been trickle charged. Features Applications Higher capacity in a smaller size and lighter weight than other battery back-up solutions (Lead-Acid, NiCd) Efficient Charging at high temperatures (up to C) 8-1 year expected life when used with the proper charge control circuitry Network storage-cache memory back-up Uninterruptable power supply units (UPS) - (HHR5SCH) Emergency lights Counication base stations (Micro cell, Pico cell) Load leveling

An intermittent timer charge improves charge efficiency, extends battery life (-vs- trickle charge) and reduces electricity consumption up to 3% compared to *trickle charge. Intermittent Timer : (see diagram) At the beginning of the charge, an IC timer is started and charging is activated at a current of.1it until the timer stops and the charge is terminated. When the batteries self discharge down to a set point (V), the timer charge is re-activated. Example of intermittent timer charger system: Average Current:.1ItA Re-charge Time: 16 hours Pulse charging can be used VB Intermittent VB *Trickle charge is not recoended for NiMH batteries. Please consult Panasonic on any NiMH applications requiring trickle charge.
