Thanks for the reply. I have checked the water and also have checked the voltage after the charge. I am getting 39 volts on a 36 volt battery. All the cells are reading 2.2 volts. I have checked them before a charge also and I get 2.1 volts per cell. I do not know the voltage per cell or overall when there is a load on it. I have sent the battery in to a battery place to have it checked out. They said they will load test it and equalize it with there machine. I hope they find something with the battery. If not I will be back to troubleshooting the lifttruck.
