What would thieves do with $330 worth of 12v vehicle batteries?
Well, I don't want to find out.

My lot isn't fenced yet, partially due to infrequent large trucks arriving. A lot of asking people and google hasn't generated how to accommodate traffic according to a certain arrangement of streets. That makes a secure perimeter an ongoing issue.
So, batteries got the most recent attention.
The stock tray is under the cab, drivers side. The cover has a rubber hood clamp, where top step meets frame of first step an imposing 1/4-20 stud and nut; that's ll that stood between their couple bottles and my wallet.
I combined two 1/2" cable clamps, a couple feet of 3/8" chain, four bits of C-channel, two bits of 3/16" square tubing, various hex and carriage bolts, and a helping of crude Yankee ingenuity.

The dog's eye view shows added parts.
Lower front and back have slots that slide over a stub of round stock, that with the rubber hood clamp kept it from lifting or sliding out.

Another shot details added material around those slots. Old slots wallered out, nearly round. Added material, not much security, but tightened up what was looseness creating a rattle.

Here, the chain is threaded over the top, secured at one end, bolted into a cable clamp. It would take a lot of cutting to get at it; time consuming and noise making. Not favorite atmosphere of a thief.

Here's the business end, both a large lock and last link tied to cable clamp. A little more room to work, twice the material to penetrate.


While the inboard side is open, that window is smaller than battery upright or laid down. Not to mention a nest of 1/0 and 2/0 stranded copper, another favorite target, out of reach.

Next I figure how to straighten tubing used to shelve cargo area, it's heavier than EMT but not quite pipe, seems about like 'rigid electrical tubing'. At 8' long, a 30" wide air over hydraulic press isn't the combination. Straightening is best done on a bed of at least .75% long as object being worked, with 'furniture' at least 1.5x height of bends getting attention. I bid once on a straightening press. Even had I won, 1700 miles from where I need it.
