3 Stage Charging Program

Stage 1 – Bulk Charge

This is where the battery typically receives the initial 80% of its charge.  The charger is operating in constant current mode, where the maximum current is delivered and the battery voltage rises to 2.4V per cell.  This stage finishes when the battery’s voltage reaches it’s peak.

Stage 2 – Absorption

This is where the battery typically receives the remaining 20% of its charge.  The charger is operating in constant voltage mode, where the maximum voltage of 2.4V per cell is delivered and the current decreases.

Stage 3 – Float

This is where the voltage lowers to the maintenance level 2.3V per cell to maintain charge.
