better still; don't bother

We are talking about BB with his well,known reputation with anything mechanical

Having been in a workshop when a car battery went 'bang' I don't fancy that much!
It literally went off like a bomb throwing acid and plastic out. I'm glad I was well out of way. My mate was welding close to it, his screen saved his face, the next day his overalls looked like they had been used for shotgun target practice!

I work in a factory that makes large lead acid batteries and it's quite common for one to go pop when they are on initial charge...not a pleasant experience if you are within 30ft of it. Had one pop while I was calibrating a high drain tester once and it cracked the extruded Ali frame of the doors

Do they not have an exclusion zone in place or power down before access policy ?

Seems strange that your allowed to be near something that can go bang with nasty consequences

If they're the standard farm gates made from galvanised round tube, forget about trying to fix them. They are made from thin steel tube & very difficult to weld - been there, done that with little success! You can never get all the zinc off plus the tube is so thin so it's near impossible to get a good weld anyway! When you add up the time you spend on trying to grind out & redo your welds it's cheaper to buy a new gate, they're not that expensive.

They're not pleasant by any means but I've repaired several (standing up perfectly to the test of time) with just a stick welder!

I've an old friend who's terrible with electricity and connected up the batteries in the cab of an excavator wrong and blew the top off one battery.
It obviously showered him in acid and blew a lump out of the roof lining. He had to get down from the machine, across the shed and out of the door with his eyes shut to get to water to wash the acid out.

Nasty!

Just reading this again this evening. If the force of the explosion was enough to crack an extruded Ali frame how did you come away unscathed either from the force of the explosion or the sulphuric acid that would have been sprayed everywhere?
