Capacity (mAh)

After charging at 0.1It for 16 hours, discharging at 0.2It.

For reference only.

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

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

With control system

* [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

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.
