That inverter was super handy on jobs and it ran a window unit and migpak welder.On the concrete storage thing.Myth.[URL unfurl="true"]https://www.mcgill.ca/oss/article/general-science-you-asked/concrete-truth-about-batteries-stored-concrete[/URL]It used to be true but batteries today are not prone to discharging on concrete.I did a test in 1993  i had been buying a lot of vehicles at auctions and had a lot of batteries.I had a brand new battery in my 1982 mustang and a friend came over and seen I stored batteries on the concrete floor in the garage and he jumped all over me.Well i bet him and a test began.Garage was separate from the houseI took that brand new battery out of the mustang and stuck it on the concrete floor in the garage.I told him 6 months from now i will stick it in the car and see if it will start it.Time came to test it.It fired right up. But not a good test so I said let me flood the engine so it cranks longer.Still fired up.So i said let me turn on my lights and key for 1 minute and see if maybe there is just surface charge allowing it to work.Fired right up and it lasted over 5 years in that car.I bet him on another occasion back in 1992 about my engine I just built not being able to seat the piston rings.He watched me build an engine and it had 100,000 miles on it with Zero ring ridge and had a golden glaze to the cylinder walls 1969 300HP 350.I milled the heads to 54cc and put fresh new  flat top pistons in it and new rings E251K moly faced.I did not hone the 100,000 mile polished cylinders no glaze breaking nothing.He said the rings will not seat. He went to auto mechanic school at Moore Norman votec and his instructor told him so.Well after 20 minute cam break-in that day in my 78 Nova I checked cranking pressure and all cylinders cranked 200 psi.I took his 20 bucks.My uncle wrote sealed power corp.  before I was born and asked them what the best surface was to seat their Moly rings and the reply back was "you know that 100,000 mile golden glaze polished cylinder wall you see in many engines , that is the best surface to seat our moly faced rings.That engine is in my 57 chevy 4 door  today and still standard bore and standard crank with over 400,000 miles on it.I like to try things first hand.</blockquote>
