*** For rapid charge: use dT/dt charge termination method. Refer to the
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:
** For reference only.
* After charging at 0.1It for 16 hours, discharging at 0.2It.
Approx. Internal impedance
at 1000Hz at charged state.

Discharge
Capacity*
Charge
[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.
Nominal Voltage
Storage
n = the time base [hours] for which the rated capacity is declared
