My Battry is totally dead, so I bought NEW Battry today, and i like to know "How to increase the life of this BATTRY" 1)--do i have to keep connect BATTRY continously over years, even i am not using LAPTOP ? 2)--do i have to disconnect BATTRY if i am not using couple of MONTHS ? 3)--do i have to keep on CHARGE BATTRY upto 90% even i am not using for couple of months, and i should leave connected to LAPTOP continously, no need to take out ? what is the best way to increase the LIFE of BATTRY. And I like to know if BATTRY Power goes to 0% then what happend, because if i am not using BATTRY for couple of months then it will go to 0%. After this is there any problem in my BATTRY. Thanks & waiting for your replies.
