SiO2, Lead Crystal, Soneil Batteries

For various reasons I have purchased a pair of Soneil, SiO2, 260ah, batteries from Azmuth Solar.

Are there any other users here of any version/brand of SiO2 (lead crystal) batteries?

Either respond here or send me a PM.

I've found this can be a hot topic, but I'm not interested in arguing.

Thanks,

Perry
