If you have a progressive 3 stage charger and plug in the progressive charge pendant you can charge lithium batteries. By pressing the charge pendant, the charger will go into boost mode 14.6 volts and after 4 hours return to a safe 13.6 float charge. Progressive recommended this to me instead of replacing the charger with the lithium charger.
