Specifications

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.

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

- 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
