Stage One – Rapid Start Charge delivers maximum charging amperage to "wake up" any
serviceable 12 volt battery and allows for quick engine starting in just 5 minutes (based
on a midsize vehicle battery at 50% charge level). When battery reaches a maximum safe
predetermined voltage, the charger will automatically signal a "beep" and move into Stage
2 of the charging process. At the end of Stage 2, the charger will signal a BEEP and move
into Stage 3 charge mode.
Stage Two – Absorption Charge maintains the maximum possible charge at a constant,
safe, predetermined voltage. During the phase, voltage absorption regulation charge, the
charging voltage remains constant, while the actual charging current is reduced to allow
for the maximum proper internal chemical energy transfer.
Stage Three – Top-Off Charge voltage is automatically maintained and reduced to a pre-
determined level while current is adjusted for a safe, effective battery charge level (step-
down regulation mode); ideal for topping off batteries that have been in storage. At the
conclusion of Stage 3, the unit will BEEP signaling the completion of the charging cycle.
The Automatic Float Charge feature is ideal for maintaining a battery. It automatically
tops off a battery as needed, to keep it fully charged all the time.
