Typical Charge Characteristics
HHR330APHCylindrical L-Fat A size (HR 18/67)
Dimensions (with Tube) (mm)
Specifications
1After charging at 0.1It for 16 hours, discharging at 0.2It.
2For reference only.
3Need 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
4With 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
