Extract battery power (5)
I believe the answer is:
juice
This might be a double definition.
'extract battery' is the first definition.
'juice' can be an answer for 'extract' (I've seen this before). I am not sure about the 'battery' bit.
'power' is the second definition.
(I've seen this in another clue)
Can you help me to learn more?
(Other definitions for juice that I've seen before include "power" , "Fruity liquid" , "Energy" , "Sap; petrol" , "fuel" .)
