The touch terminals are equipped with rechargeable lithium batteries that are not user-replaceable.
The battery is needed to keep the real-time clock running (date and time).
When the touch terminal is installed for the first time, the battery must be charged for 48 hours. When
the battery is fully charged, data backup at 25°C is guaranteed for 3 months.
