The PulseTech 2-Station 12-Volt Battery Recovery Charger, No. SC-2, is designed to recover, charge, maintain and desulfate as many as two 12V lead-acid batteries at a time. This compact and portable recovery charger works with any 12V battery type, including VRLA, AGM, gel and flooded cell. The dual recovery charging stations operate in isolation, allowing any combination of battery brands or types to be recharged simultaneously. The charger's patented Pulse Technology removes sulfate crystals from the battery plates, increasing the battery’s ability to accept, store and release energy, extending battery life up to five times. The SC-2 features five LED battery-status indicators, replaceable cables, a case and a one-year warranty.
