Review on ⚡️ PP-12-L PowerPulse Battery Maintenance System – PulseTech 12V by Sean Perry

This desulfurizer really works. I had a 5 year old battery that turned out to be minimally good in the stress test. I connected this desulfator/conditioner to the battery while charging (because it drains the battery) and let it sit for a month. A month later, according to Cold Cranking Amp, the stress test showed it was in the best possible range. Fully charge the battery before connecting it. It flashes when desulphation is in progress. Update: Make sure the battery voltage is kept above 12. Using a weak charger with this desulfator will drain the battery to the point of no return.
