In this video, Jeff Bragg managed to revive 3 out of the 5 Yellow Top Optima spiral-wound batteries he obtained from work to use as his solar battery bank. Though not mentioned, it is obvious the batteries were in poor condition as an attempt was made to revive them with the Infinitum Desulfator.
Jeff managed to bring up the voltage of 3 out of 5 batteries from 12.4V to 12.95V while charging the batteries with the Infinitum Desulfator installed.
Though a battery’s increased resting voltage is a good sign of its capacity to hold a charge, using battery tester to test the battery’s internal impedance would give a more accurate reading of a battery’s true condition.
I would buy again as it has definitely helped

Spiral Wound Batteries Do Suffer From Sulfation
Spiral wound batteries are AGM (Absorbed Glass Mat) batteries constructed in such a way that they can be positioned in any orientation without having to be kept upright. Despite of this structural uniqueness, the internal chemical composition is similar to any AGM battery or lead acid battery and will suffer from sulfation. Both battery types contain the same lead and lead oxide plates soaked in sulfuric acid and will eventually form an insulating sulfate crystal barrier within the battery over time.
