Kept LP-E8 batteries for Canon t3i on dual charger for weeks

For several weeks, possibly up to 2 months, I have had four of my batteries on two
PhotoPro dual chargers.
I have one native genuine Canon LP-E8, and this one doesn't have a bulge on its belly.
I have one newer
Photive LP-E8 battery in my collection, and this one has a slight bulge to it.
The
unbranded ones are bulging enough that it takes effort to force it in and pull it out. I'm worried. And I'm probably retarded.
Should I replace all of these batteries that are bulging?
And as best practice, next time I should just take them off the battery charger once they hit 100%, yes?
