Interesting situation. Put one of my BPU-30 batts on its Sony charger. Several hours later I came back to see that ALL the LEDs were flashing on the battery. I can't get them to stop! Have tried putting it on an EX-1. Ive put it back on the charger. Still flashing. Anyone else ever experience this?
Put it back on the camera and somewhere in the menu is a way to check out the battery condition, provided it still has enough life to boot up the camera. You may fine it was reached the end of its life.
