Great responses. But to answer your question more specificly Jordan, an electric lift truck has as much lifting "power" as a gas unit. However, lifting and sideshifting and any other attachment is where the electric trucks use most of the battery "power". It is extremely difficult to say how long a charge will last. A given truck in application "A" with a poor operator may last only 3~4 hours. The same truck in application "B" with a good operator may last an eight hour shift.
