Dead charger?

[majhi]

I have two eGo batteries, a 900mah and a 1300mah. Both of them were charging fine last night. As of right now, neither of them are charging when connected to the charger. I've cleaned the terminals on both the batteries, as well as the charger. I've wiggled the center pins. I've even taken apart the charger to see if there were any disconnected wires. No luck. I just can't get my batteries to charge. Is my charger dead? The green light is on, but never changes to red when I hook up the batteries.

Update: I'm pretty sure it was the charger. I hacked apart my eGo charger and a V2 charger I had laying around and soldered the eGo head onto the V2 charger. My batteries appear to be charging now.

How the hell can a charger go bad? That seems a little strange as there's really nothing to them. One thing that I have found is that a clean and dry contact is necessary. I always clean the battery side and forget to clean the charger side. Both sides have to be dry and clean i would guess for proper operation because that's the way they are when their new.
