So we've done an AC conversion to my best friend's Primavera. It works great, but there's an empty spot where the battery used to be. There isn't much space to carry tools on a smallframe Vespa, so I came up with an idea. If I gut the dead battery and pull out all the plates, it would make a nifty toolbox.
So I rinsed the battery acid out several times while wearing chemical resistant gloves. Then I took a dremel to the top of the battery case and separated it from the bottom. I had to saw through the battery posts.
After knocking the inter-cell connectors apart with a chisel, I pulled the plates out and discarded them. I found an old door hinge in the junk box and fastened that to the back of the battery case so that the lid would close down normally. The battery-shaped tool box fits right back where it belongs and holds a few essential items in case a roadside repair is needed.
