In the Power Plant
levelAt the very start,
you can climb up the wall opposite the fan
by swinging your arms back and forth to grab higher. Once at the top you will see 3 terminals. One of which is connected to the transmission tower via cable.
Line up the jump and grab the cable. It will automatically swing you towards the battery
in the statue's hand. Make sure you either grab it or knock it off.
In the room after the forklift area
with the giant statue.
Again no easy jump spots
to get to the top. So you'll have to scale the base by swinging back and forth.
Once you're at the feet of the statue run, jump as high as you can, and grab the book.
You may need to use the swing method to get up and stand on the book. Now turn around jump towards the brim of the statue's hat,
again may need to use the swing method to get fully up. Once you feel safe enough to stand on the hat go ahead and jump towards the battery and make sure to either grab it or knock it off. This battery is also 1 of the 3 used for the 'Will It Fry' achievement.
