The effect of increased internal resistance means that they will now self-discharge faster, and the voltage drop under heavy load will crash much sooner. They may appear to have lost capacity / runtime. They haven't really, but *access* to the cell's material is restricted internally with secondary reaction garbage layers.
You may get some life out of them, but typically what happens is that one day they seem perfectly normal, and then one charge cycle later, they are dead. There's plenty of material left, but the SEI layer just closes down. Much like wiping up a gravy spill with a brand new sponge. Plenty of sponge left, but the pores are so clogged that it no longer functions.
Fortunately, your cell is inexpensive. Had this been done to a 200ah prismatic that would have been a much larger story.
