Inquiry (采购产品): P11104DC Battery &Pressure Guage Hello, My question is how can you tell if the battery in the lifting device is strong enough to last if setting the glass takes longer than normal and what happens if the battery goes dead during the lift. What is the correct pressure reading on the guage when attempting a lift. **** Hidden Message ***** Bill Giovanetti 1737 S.
