Yes, the battery will do it...
The BIOS chip can only remember things if it has power. If you take the battery out, you are removing its power and therefore it forgets everything.
EDIT: So you had the CPU at 2V? Did you read up at all on over clocking, or did you just start changing values at random?
With the VRAM and VCORE up that high, who knows what you did. Possibly fried the CPU.
Next time it'd be in your best interest to read up about it.
