i wonder about DOD on these batteries. as stated 36 kwh battery. using 80% you would have 28.8 kwh available power before recharge is required. Jungheinrich has proven to be a very efficient machine in the U.S. market so I can absolutely believe this claim. In medium or light duty operations. IMO high cycle operations running 2 shifts per day would destroy a flooded battery in 3 years or less. 8 hrs recharge - when is cool down? And yes i know about the HF charger.
