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.
