Has anyone ever had one of the Prestone jumper packs from the 90's? I bought this new, and can usually date things based on what car I had at the time. I bought a 1988 Shelby Z Daytona in 2000 and went junkyarding almost weekly to find nicer parts, add options, etc. I already had this jumper at that time so I could remove the power enthusiast seats I found. After countless jumpstarts for friends, family, and myself, powering electrical items in junkyards, testing parts at home, banged around, stored for extended periods, this thing can still start my V8 Dakota after the battery died last week. This is a lead-acid battery that's over 20 years old. I'm pretty sure this wasn't designed to last that long.
