keeping macbook always connected to a power adopter will effect the battery

can i keep my mac always connected to power adaptor will it effect the battery of my mac or not

when i start using mac for sometime i use it on battery like 10 % (i will use it from 90% to 80 % ) so create some activity in battery and then connect to a power outlet when charge was at 80% percent and use it for 5 to 6 hours and disconnect the charger and use it for a while like 10% discharge again (100% to 90%) and then shut it down (not just closing lid)

is this the good practice or not
