I have Sony Handycam DCR DVD610 which works perfectly fine with the power adapter on. But if I take it out and put it on battery power, it turns off for 20 seconds and will say battery exhausted. Even though the battery was fully charged. I even tested one Chinese charger and it wont work. The weird thing is, when i plug in the charger, the battery jumped from 1% to 100% (1 min to 107 min.) By the way, we did not charge or use the camera for a WHOLE 6 YEARS. It was just laying there, picking up dust.
So please, can someone help me with this problem.
