Need specially designed control system
Control System:
dT/dt cut-off; 1 to 2°C/min
- V cut-off; - V per cell = 5 to 10 mV
T-control; T=65°C
Rapid charger timer; 2.4h (at 1.25a)
Trickle timer; within 2h

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.
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.

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
