• Force Bulk – This selection restarts the Bulk cycle from any stage in the
charge cycle. Restarting the Bulk stage is useful when a full Multi-stage
charge cycle does not bring the specifi c gravity of the batteries to the
proper level.

Figure 5-14, Force Float Mode
• Force Float – This charge profi le "forces" the charger to stay in the
Float mode continually as long as AC is present and the charger is active.
Force Float is most often used when another source of charging such as PV,
wind or hydro is available to keep the batteries at the Float voltage. If AC is
disconnected and then reconnected, the charger will go directly to the Float
mode and will not do a Bulk or Absorption charge cycle.
Info: If the battery voltage falls ≤12.1 VDC (12-volt models), ≤24.2
VDC (24-volt models) or ≤48.4 VDC (48-volt models); the unit will
automatically begin Bulk Charging.
CAUTION: Using the Force Float mode may not fully charge the
batteries. Most batteries require a Bulk and Absorption charge cycle
in order to fully recombine the electrolyte in the batteries and bring
the specifi c gravity to the proper level. Be sure to check with your
battery manufacturer before using this setting.
