How do you move a 500-pound battery stacked on a second battery from a horizontal position to a vertical position on the ground 2 feet below? Very carefully! To accomplish this without assistance, I stacked blocks of wood to support the weight as I pushed the battery off the edge of the box underneath it. I then used a lever and fulcrum in between the supports to carry the weight as I removed one pair of blocks at a time gradually tipping the battery to an upright position. It took about an hour to complete the task and I was very pleased with the outcome. All this effort was necessary so I could expose the back side of the unit to confirm how it will be mounted and where the wiring needs to be located.
