The working time of battery will be effected by many
factors, such as ambient temperature, recharging time,
recharging and discharging times. For safety, we suggest you
recharge the battery full or prepare several full batteries before
operation.

The battery symbol only indicates power capability for
current measurement mode. The power consumption in distance
measurement mode is more than in angle mode, if the instrument
enters into distance measurement mode from angle mode, the
power maybe auto-off because of lower battery.
