I haven't seen this product before but you've got me interested. I think I will give it a go, when I replace the house bank on my boat.
Double the lifetime is a huge win and I know I will have suplhation issues when on anchor for long periods.
I've researched it & it's phosphoric acid,at a highly inflated price. The chemistry is logical. Food grade phosphoric is around $20/ litre. Without looking at my records I think 20ml / cell in z70 size battery is all that is required. ( follow the inox directions as to how much per cell) I've witnessed it clean up dirty looking acid in battery cells. As to adding to longevity it a bit hard to tell from my last pair of new batteries as some low life stole them, and a heap of other gear ! If your using flooded cells it's well worth a try & if you get a litre of phosphoric acid you have plenty of great metal cleaner left over
Just bought a new lead acid start battery.
Before the purchase I searched the net for battery revival/ recon stuff.
WD 40 anyone?
Really a load of rubbish , but one of those Pakistani mechanics sites had a young guy (in thongs and no safety glasses)
ripping the top of a battery.
He removed the sulfated cell and added a new one.
Painful to watch, but the take away was that the dead cell fell apart in his (ungloved) hands when he removed it.
I realized that a dead cell is REALLY a dead cell.

Many years ago at a Naval Air-station base where I was stationed more many years they had a battery maintenance workshop. It was for maintaining aircraft batteries but they also serviced the maintainers car batteries. Anybody could drop their batteries in there in the morning and pick them up in the afternoon. I only used the services once and you never got to see what was done but I was told it consisted of dropping the battery a couple of feet onto a plank of wood. Inverting and draining the acid. Replacing the acid with fresh stuff and charging the battery. It worked. This was an initiative introduced by the navy commander to improve the attendance rate of sailors in the winter months and stop the flat battery excuse.
These days just spend $20 on a pulse battery charger. I've just bought a second one to give to a gran kid.
