Lithium-ion batteries are designed to stay in the forklift AGV. They do not need to be removed for recharging. They can also be charged throughout the day, so when an operator stops for a break, they can plug their truck in to charge and come back to a recharged battery capable of running for the remainder of the shift. A lithium-ion battery can gain a full charge in one or two hours. Lithium-ion batteries are therefore the more economical option for warehouses running 24/7 operations or multiple shifts back to back,
