D10A backup battery questions
I've had my RV7A for two years. I bought it from the original builder who finished it in 2008. To my knowledge the backup battery on the Dynon D10A has never been replaced. It still seems to work fine.
1. How often should these batteries be replaced?
2. Is this something I can do myself or does it need to be sent back to the factory?
3. If I can do it myself does anyone have information on how to do it?
4. If it must be returned to Dynon does anyone know approximately how much this cost?
