Located in an alleyway to the left of the street after the buildings. Stop just before the Quarantine Zone and then zigzag down the long alleyway and the battery will be at the end on top of a dumpster.
Located on the roof across from the second floor hotel entrance in the alleyway. To reach it jump on the dumpster in the corner of the alley near the metal stairs on the side of the building then turn and face the stairs and walk forward until it looks like you are going to fall. If you then jump and quickly tap A just before you would miss the stairs Chuck will grab them allowing you to climb to the top. To get the shed key which is inside the building you have to hop over the railing at the top of the stairs so you are standing on an air conditioning unit and look over at the building across the alley to the right of you. There you will see an air conditioning unit sticking out in front you. Walk to the edge and quickly jump by tappig A and Chuck will grab it. At this point you will find a handgun and if you now climb upon top of the building the construction hat is in the right corner by the street.
