Battery Optimization of Precision M4700..

Hello Everyone,

What do i do, when the battery is fully recharged?

1) Should I remove the charger?

2) Or i can leave it plugged in?

Btw the charger I am using is 19.5V with 12.5 Amps, is it okay? Becuase the recommended is 9.5Amps with 19.5V?

Thanks In Advance..
