These work for me
Several times over the past few months folks have posted about battery issues. I posted in a reply about the set that I got with my boat that don't eat the storage area they are stored in. They're made from welding lead like an arc welder would use, and these were new. The clips and connectors might not be as cheap as a store bought set, but they lay flat real well. They're 7 feet long and reach from the batteries one one side to the other with some to spare. Real handy when the start battery goes south. Here's the pics, sorry I took so long. Hope this answers the questions.
