What Happens If You Revive a Healthy Battery?

[SegNerd]

I have two sets of lithium-ion Segway batteries. One set, I foolishly left unplugged for too long, and they stopped working.

I have ordered a reviver rental from MTO, and it is on its way. I understand that a revival isn't the same as a full reconditioning, but what I'm wondering is, since I'm going to have the reviver in my possession anyway, should I run it on my healthy set too, or just the ones that need it?

Would this be good for them, bad for them, or do nothing?

Thanks for any info.
