I have a very old electric forklift that has a huge inoperative battery. I have been operating it with a couple of 12 volt auto batteries perched on top of the battery housing.
I did some investigating and found that the battery is composed of 12 2 volt cells 6" x 7" x 24" encased in plastic housings.
I am thinking about pulling all the cells out of the housing which is 1/4" steel, filling it with concrete to about a foot from the top and installing 4 6 volt golf car batteries.
The battery serves as ballast for the truck and I was wondering if the concrete would weigh as much as the removed cells.
Thanks in advance for the help and comments.
