Until the introduction of modern lithium-ion batteries, electric forklifts
have been restricted in their capacity. Electric forklifts are inefficient after crossing their limit for carrying capacity, speed and operating time. Alternative forklifts, those operated by petrol or diesel, have a large disadvantage because they could hardly be used in enclosed rooms. Their emissions (soot, carbon dioxide and carbon monoxide) meant that the operation with a diesel or petrol operated forklift in enclosed spaces was too dangerous. Carbon monoxide can bind itself to the haemoglobin in human blood 300 times more than oxygen can.

were developed partly as a result of this discovery. This type of forklift has a normal combustion engine, but do not result in any dangerous emissions.
