Battery: For radio version11.3
Technical data
Nickel Cadmium battery
4.8 Volt
4 Ampere hours
The measured battery voltage with Ni-Cd cells gives i
no statement about the charge state "full" or "half
full". To prevent deep discharge monitors the proces-
sor measuring the battery voltage and switches at
4.2 V to the relay.
