RUNAMUCK Posted March 15 Report Share Posted March 15 Can a DC TIG not arc too? Quote Link to comment Share on other sites More sharing options...
tortron Posted March 15 Report Share Posted March 15 It can, but I'm saying most people have a dirty old arc welder to give it a bunch of amps (for cheap)Â Quote Link to comment Share on other sites More sharing options...
Bling Posted March 16 Report Share Posted March 16 Just hook it to the wall, job done / acid in many places. Or wrong power flavour? 1 Quote Link to comment Share on other sites More sharing options...
tortron Posted March 16 Report Share Posted March 16 You want to give it some short sharp shocks to break up the crystals that form, the smart charger does pretty much that  You can also break the crystals up by giving the battery heaps of amps and not letting it boil dry Quote Link to comment Share on other sites More sharing options...

My 2.2A charger wasn't doing the biz, and @RUNAMUCKhas been kind enough to loan me his 3 or 4A "Pulse charger" (MSPaint graphs coming later). It's slowly clawing the peak voltage up, which looks promising. My Q is: what happens if I invert the battery and slosh it around to try and loosen the crystals / acid-salts/whatever while it's charging. Does it short through the electrolyte and explode, or go flat real fast or some nonsense? ( @ajg193, Autosparkies?) Anyone with experience with flooded lead acid batteries from roll-overs etc? Thanks team. Epsom salts and there is a thing you can connect across the terminals called a de sulpalter  Quote Link to comment Share on other sites More sharing options...
h4nd Posted March 16 Report Share Posted March 16 Oh yeah. I happen to have an excess of epsom salts. Quote Link to comment Share on other sites More sharing options...
ajg193 Posted March 16 Report Share Posted March 16 Doesn't logic dictate that if epsom salts actually made a shit battery really good then the factory would put it in? Quote Link to comment Share on other sites More sharing options...

I had a 7 year old battery that wouldn't even start a 4 cylinder work for another 3 years cranking a v8 after drilling holes in the top and putting in a spoon full of Epsom salts into each cell, I even sold the battery with a tractor in the end. 1 Quote Link to comment Share on other sites More sharing options...

Logic also dictates that if you make a battery not last a long time, you can sell more batteries. Guess which logic a battery manufacturer goes with?  5 Quote Link to comment Share on other sites More sharing options...

Muncie Posted March 16 Report Share Posted March 16 I used to bolt batteries to the vibration bench at my old work while charging certainly made them better then ever after they sat for a week all crap rattled off plates settles to bottom of battery.
