Two-Year Warranty
The IQ4 Smart Charge Controller provides intelligent automatic 4-stage charging
control for your IOTA DLS Series Battery Charger, keeping batteries fully charged and
operating for long life. IQ4 Smart Charge Controllers are available for any DLS Series
Battery Charger model and are backed by IOTA’s Two-Year Warranty. For 4-Stage
Charging, either the external IQ4 pendant or a DLS Series charger with built-in IQ4
technology can be used.
FOUR-STAGE SMART CHARGE CONTROLLER
The IQ4 Smart Charge Controller allows the DLS Series Battery Charger to operate as
an automatic “smart charger,” delivering the charge the battery needs at the time it needs
it. The IQ4 uses four different charging modes to keep your battery in peak condition:
BULK STAGE
The Bulk Stage of the IQ4 allows the batteries to be charged from the full rated output
of the charger (for example: a 12V charger will charge at a maximum of 14.8V*). This
increased charging period reduces the overall charge time of the battery.
ABSORPTION STAGE
After the Bulk Stage, the IQ4 then moves to the Absorption Stage (14.2V for a 12V
battery*). This mode will continue for up to 480 minutes (8 hours) to ensure that the
battery receives a complete charge.
FLOAT STAGE
During the Float Stage, the IQ4 reduces the DLS charge voltage. This reduced volt-
age maintains the full charge while minimizing ‘gassing’ of the battery. The IQ4’s Float
Stage prevents boiling and bulging of the battery caused when the battery is exposed
to higher charging voltages for too long.
EQUALIZATION STAGE
If the batteries remain in a “float stage” for a seven-day period, the IQ4 will switch the
DLS charger into a pre-programmed Equalization Stage. This protects the battery by
dissolving any sulfate layer on the battery’s internal plates and avoids stratification that
can occur when a battery has not been used for extended periods.
*Refer to the Charging Voltages table for the different charging voltage levels.
