Built-in and non-detachable 3.7V 1000mAh
Lithium battery
Charge: Phone chargers are recommended.
Please use 5V 1A chargers and Type-C
charging cables to charge.
When we can not activate instruments or there
is a blank battery symbol flickering after it has
been used for a period of long time, we should
charge it in time. After inserting USB into it,
the battery symbol bar scrolls to display,
and when fully charged, will display and
flicker.
Charge the instrument fully and do it every 6
months to avoid damage to batteries when the
Instrument are not in use for a long time.
