Hi, guys. I tried posting to the model specific forums but since I'm a new member I'll give it a shot here. I got two ego twist batteries about 3 months ago and I noticed recently that one of them has been pulling harder than the other one. I took the tank off and noticed that there is a good amount of bluish gunk where the battery comes into contact with the tank and around it. Any insight into this? I have since stopped using it, but it is a little worrisome since that's where the air goes in and stuff. Any visibility into this would be greatly appreciated. Thanks!
edit: I should clarify that the battery is leaking blue residue, not the tank. Hence the concern.
