2.8  Battery - Management 
Two Bargraph scales show the charge state of the batteries. The Flytec 6020 is provided 
with 2 battery banks with 2 batteries each. Bank 1 must always be loaded. Bank 2 may be 
kept unloaded. However, it is highly recommended to also equip Bank 2. As soon as Bank 1 
batteries are discharged, the instrument automatically switches to Bank 2. We recommend 
to place the partly discharged batteries of Bank 2 after a long flight into Bank 1 and to place 
new batteries into Bank 2. In doing this it is ensured that you may use up the batteries 
completely without taking the risk that during a flight all the batteries are discharged.  
Bank 1 
Bank 2 
The following batteries are appropriate for use: 
•  2 pieces each per Bank Alkaline High Power batteries 1.5V size AA.  
Estimated operation time - 2 times 20h = 40h in total 
•  2 pieces each per Bank NiMH accumulators 2100mAh or more, 1.2V size AA. 
Estimated operation time - 2 times 15h = 30h in total. 
The correct battery type needs to be set in Main Setup Menu 
⇒
 Instr.Settings 
⇒
Batterytype. 
If a wrong setting has been entered, it may induce to the result that the instrument 
prematurely switches off completely, when changing from Bank 1 to Bank 2.  
We recommend not to use NiCd accumulators. These batteries have significantly reduced 
capacity and they are less environment-friendly. Also the switching threshold data are not 
laid-out for NiCd Accumulators. 
The estimated operation time mentioned above is based on normal temperatures (20-25 °C). 
At low temperature the batteries and accumulators have a considerably shorter service life.
