the first use of it was at 56% and the pc has run 2 hours with it
then I did the recharge my pc indicates that the battery 9%
since that it was 100% charge I turn on it since soon 3:30 ET I still have 34% charge
it is really top this battery
what matters is well c charging for the first time and that she must either discharge max
the life of the battery depends otherwise it n not reached its maximum capacity
n hesitate not at the reception of the empty battery to the max and then do it well at max load
then again allowed to discharge max and so on
No veiled I electrotechnicien not hesitate and I know what I'm talking
nothing to say as of ab on amazon they are very satisfactory
