NICKEL METAL HYDRIDE HANDBOOK AUGUST 2005 NICKEL METAL HYDRIDE BATTERIES: INDIVIDUAL DATA SHEET This information is generally descriptive only and is not intended to make or imply any representation, guarantee or warranty with respect to any cells and batteries. Cell and battery designs/specifications are subject to modification without notice. Contact Panasonic for the latest information. Typical Discharge Characteristics Typical Charge CharacteristicsHHR300CH Cylindrical C size (HR 26/50) for backup use Dimensions (with Tube) (mm) Specifications 1 After charging at 0.1It for 16 hours, discharging at 0.2It. 2 For reference only.
3 Need specially designed control system
Control System: dT/dt cut-off; 1 to 2°C/min -UV cut-off; -UV per cell = 5 to 10 mV T-control; T=65°C Rapid charger timer; 2.4h (at 1.25a) Trickle timer; within 2h
4 With control system
Battery performance and cycle life are strongly affected by how they are used. In order to maximize battery safety, please consult Panasonic when determining charge / discharge specs, warning label contents and unit design.
