But the charger also "reconditions" batteries, or so the advertising and

never used this feature, but I loaned the charger to a buddy and he
reports that it actually revived two batteries he was about to toss. I
don't have any other details.

I've got the Walmart version of the same charger. You can revive
batteries, not for ever, but you can get some extra life out of them.
