So what's the correct way to use Intelligent Battery?

I bought a Phantom 4 Advanced last year with an extra battery. I have only taken about 3-4 flights in the past year. I kept one battery within the battery and the other one in the box.

I was trying to charge the batteries for a flight, and apparently the one in the aircraft is dead… there is no LED light indicator whatsoever.

So I finally looked into the battery manual and realized there is a lot to know about this “Intelligent Battery”.

So what’s your suggestion? For someone that doesn’t flight often, should I always take them out from the aircraft? Should I discharge them to 60% within the aircraft, or should I let it discharge on its own? Should I take it charge and discharge it every month?

They should last a long time if you maintain them like this:
