Now that I'm well into the golden years, I've discovered DIY replacing standard Group 26/27 batteries (~30/50lbs) is a lower back wakeup call. Even worse Odyssey Group 27 batteries (we use in our older mopars) weigh nearly 70lbs. There's all manner of lifting tools which don't really reduce the back strain.
So got to thinking, can I use my 2 post lift to replace batteries. Used an extra lift pad extender that nearly fit inside some scrap 2x2 steel square tube (1/8 walls) for jig post. Also had some telescopic, perforated steel square tubing leftover from another project that could be a jig arm. All that was needed was a couple threaded hooks for the battery handles. Some cutting and welding, presto a $7 lift battery jig. Couple pix of mockup with Rebel to size the lift arm, final painted. The power cable/switch on top of the battery runs to a rear connector for my trailer winch.
