Battery Operation
The device runs on rechargeable lithium-ion batteries. The batteries can be operated for approximately
12 hours within a normal usage i.e. 20-30 measurement per hour. The device has a charging indicator
LED at the top button. The charging indicator will change to green once it is fully charged. When the
battery gets low there will be an alert on the application to charge. Once it is below 10% there will be a
beeping sound. At this status, it is still possible to use the device for another one hour. However, it is
recommended to charge the battery at this status. If the battery is not charged there will be a second
warning message when the battery is empty and several beeping sounds before the instrument is
automatically shut down within 10 seconds.
The battery is standard Lithium-ion battery with a lifespan of about 500 full charging cycles.
Subsequently, the capacity and operation time of the battery may vary. A fully charge battery will self-
discharge over a time of 30-40 days. After this time recharging of the battery is necessary. Charging
time for an empty battery is 5 hours.
NOTE:
If Photopette shuts down during a measurement process, the data of the last measurement will
be still retained in the dataset.
