Typical Discharge Characteristics

Typical Charge Characteristics

HHR300CH 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.

Note:

[It] was previously expressed as [C]. [It] is an IEC standard expression
for the amount of charge or discharge current and is expressed as:
It(A) = Cn (Ah)/1h.

• [It] is the reference test current in ampres
• [Cn] is the rated capacity of the cell or battery in Ampere-hours.

n = the time base [hours] for which the rated capacity is declared
