hi Yogesh sir so u mean i should get a battery with more mWh to get more hours per charge? so lets say i get 3 hrs battery backup with a battery of 57720mWh so if i get a battery with 115440mWh i will get 6 hrs backup time but is there any posibility that i can harm my computer by getting a battery of more mWh? if yes please recommend the maximum mWh battery that i can get. thanks for such a nice explanation
