Q: How long roughly do you think it will take to re-charge dead battery? Been charging for almost 24 hours and light is still amber.

A 'fairly' dead battery should charge up in about 24 - 36 hours. If the battery has access ports, you might want to check the water level (DISTILLED water only). If it is low in any of the chambers, then you would fill that chamber with distilled water up to the bottom of a concave meniscus level at the markers. ( http://en.wikipedia.org/wiki/Meniscus ) If there are NO access ports on the battery (sealed) and the light does not change to green after about 48 hours, you might think about getting a new battery. Make sure that the terminals are clean and that the connections to the charger and to the battery are solid.

Q: How long will this reach? From recepticle to battery? Also does this come with the "quick connect" cable or just the alligator type clamps.

The power cord to the charger is 6'3" long. The cord from the unit to its end is also 6'3" long. It ends in a quick connect/disconnect plug. The alligator clamp cord plugs into that connector. So the overall length from wall outlet to the battery is about 14'. If that's too short you can order quick connect plug extension cords. They make one extension cord that's 24 feet long. I use an extension cord that's about 2 feet long with a quick connect on one end and two rings on the other. The rings fit onto the bolts of the battery clamps. I leave it connected to the batttery and the other end is accessible through the grille, so that I can plug in the unit without having to open the hood.

Q: When connecting to the car battery; Should the negative lead be connected to the negative or the engine block/frame of vehicle?

The reason to connect (& disconnect) on a grounded member rather than at the battery is to avoid the risk of a spark igniting any combustible gases that may be surrounding the battery. Although the risk is low with a low amperage charger like this, it's a good practice to make the final connection to a ground remote from the battery. Just ensure it's a GOOD ground. My uncle had a battery blow up in his face (albeit under different conditions) and I can attest it's nothing you soon forget.

Q: Does the quick disconnect stay attached to the battery while driving the vehicle?

Yes, the pigtail comes with a rubber cover or the pigtail end that is not attached to the battery is a female connector. Either connector is safe to keep attached to the battery.
