Soon as the terminals connected a mini electronic buzzing began from the motor area. 2 months later it's now totally dead, my sunroof won't close properly and there is a swimming pool on the passenger floor. Exide Edge works great on it's own, the thing went from 3 turns to start to roaring to life after one. Any diy ideas?

Are there any aftermarket accessories installed - supplemental antitheft/alarm system, remote start, etc? - dead battery likely caused by some sort of parasitic current drain, often because of an installed accessory. Swimming pool may be unrelated - could be a blocked A/C condensation drain tube, or leak from a defective windshield weather strip.

OR the sunroof that doesn't close properly.

You may also have something that is using power that is staying on and slowly draining the battery. Had this happened on a Neon where a very dim light under the dash was stuck in the on position. Had no idea why it stayed on after the car was shut off so I disconnected the bulb. Even at night I could not see this bulb lit up but I used a towel over my head to see if anything was glowing and found the problem.

Bad battery my butt, thing's been parasitized for 3 months and still works great. It's like the actual motor has a door buzzer alarm deep inside. Just disconnected red terminal and cussed. You should hear the water sloshing. It's like driving inside a half full 2 liter bottle.

Finding parasitic load is time consuming. Put an ammeter on the battery ground terminal and pull one fuse at a time till you find the circuit causing the load. Then work your way through that circuit one component at a time to find the culprit.
