Battery Maintenance
The battery’s life and performance may be affected by temperature, condition
of the battery, and the weight of the user. Charging the battery continuously for
a long duration (more than 24 hrs) before the first use can reduce the battery’s
service life.
When charging a new battery for the first time, it must be fully charged (about
24 hours) in order to fully activate the battery.
It is recommended that you charge the battery for the second time, when the
lowest level of the LED light on the control panel flashes. In other words, fully
discharge the battery before the second charge.
