I have a Canon Powershot S60 which came with a battery charger. Okay, here's the deal... When I put a battery in to charge, normally there are lights that are a steady red with a drained battery. When the charge is done, the light is supposed to change to a solid green.

What is happening now is, after a normal charging time, instead of the light turning green, it blinks red/green/red/green continuously. It has done this with the two batteries that I have. (The past two charges.)

Does anyone know if I should buy a new charger. I haven't been photographing for long enough periods of time to tell if the battery is lasting. (Which I will try to do and check the length of time.)
The batteries and charger are only 10 months old.

I called the camera shop, and I got a generic response. I don't think he knew what he was talking about. He told me that the charge was probably not done yet. Well, to borrow a phrase from Penny, geeze Louise, I think I would know if it was done charging or not. I told him that it didn't do this before! He was no help.
