Battery clamping

[Reckless Rat]

Mine has a length of bar 1/4" with a right angle on the bottom end. It is passed through the drain hole in the battery box and up to & through a piece of angled alloy sheet that fits onto the top of the battery. The top end of the bar is threaded and locks into place with a double nut. Been like that since time mint imperial and works well. I use a wooden spacer to keep the battery firm up against the side of the battery box. I'll get you a pic tomorrow.
