Past time you get a new battery.......
The problem will be finding one that is any good. I service a couple those G74s in the neighborhood and I have yet to find good batteries for them. The batteries I have purchased online have been bad (less than 50%). I have a shop charger to charge these batteries out of the laptop and so far have no purchased a good battery that will accept a charge. These batteries are all flat and once flat will not recover.
I advised my neighbors to retire their laptops.
You may want to do the same.
Good Luck
