Weird, it seems that Azimuth Solar seems to think they are the same:
Lead Crystal / SiO2 batteries
Unless I’m missing something, from all that I can tell SiO2 is the molecular definition for ordinary beach sand (or silica, which has ionic-transfer friendly lattice-crystallin structure), lead, and I believe some sort of mediating electrolyte, presumably an AGM like sulfuric acid paste (Though it’s not exactly clear to me why the purpose for the silica?)...Thus the interchangeable monikers of SiO2 and Lead Crystal.
Might be interesting to do a deeper dig to understand how all the physics differs from FLA, but SiO2’s exist for a valid reason - my ‘best guess’ is that this particular recipe results in an ionic-transfer ripe, freeze resistant battery...
But I could be wrong...
