Seems to work like a battery. I'm pretty sure my wet lead-acid marine RV battery is sulphated (loses a full charge in a few hours under minimal load), but desulphation mode never activated when I plugged it in. (MOTOPOWER Junior MP00205B 12V 1000mA.) The clamps seem pretty flimsy (see photo) but I still use ring connections instead of clamps. See attached images for instructions and specifications to answer many questions.
