Intec Power XT3™ regulates the whole system under 4-stage
charging platform. Uniquely formulated 2-step Constant Voltage Charging
combined with Constant Current charging which optimizes battery charging
performance and Pulse Charging which helps reduce battery plate sulfation.
Maintenance Charging mode w/ Auto Wake-up function is automatically
switched on upon completion of charging, maintaining optimum battery
charge condition.

Switching Mode Power Supply
Compact & Light Weight Construction.
High (80%) AC-DC Power Conversion Rate.
Reduces Battery Plate Sulfation Through Pulse Charging.
Secures Stable Output Under Power (Grid) Variation.

A switching-mode power supply, SMPS:
An electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other
power supplies, an SMPS transfers power from a source, like mains power, to a load, such as a personal computer,
while converting voltage and current characteristics. Unlike a linear power supply, the pass transistor of a switching-
mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in
the high dissipation transitions, which minimizes wasted energy. Ideally, a switched-mode power supply dissipates no
power. Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or
lighter weight are required.

Desulfation
Pulse Charging –Battery plate Lead-sulfate crystalline build-ups are reduced, improving
battery condition.
Reinforced Activation –High voltage pulse charging loosens & removes lead-sulfate
residues from battery plates.
Results: Improved Battery chargeability & capacity
Prolonged battery lifespan
What is Sulfation?
For lead-acid battery, during use, small sulfate crystals form, but these are normal and not harmful. During
prolonged charge deprivation, however, the amorphous lead sulfate converts to a stable crystalline that deposits on
the negative plates. This leads to the development of large crystals, which reduces the battery’s active material that
is responsible for high capacity and low resistance. Sulfation also lowers charge acceptance. Sulfation will cost
longer charging time due to elevated internal resistance.

Reinforced Activation Mode
For batteries that cannot be charged normally, might be in poor condition due to
temporarily over draining or sulfation, manually switch on Reinforced Activation Mode.
The Reinforced Activation Mode removes sulfate residues from battery plates and
attempts to reactivate battery chargeability by higher voltage pulse charging .
Maximum charging time of 30 minutes is suggested to prevent battery damaging.
Remarks:
Reinforced activation is limited for those batteries:
* with physically damaged electrode(s).
* with exceedingly contaminated electrolyte solution.
* with insufficient electrolyte solution.
* over-period storage.
Do not exceed maximum charging time of 30-minutes.
Discontinue charging when battery housing temperature reaches or
above 45-50˚C.

Maintenance Charging Mode
9
Maintenance Charging Mode is switched on automatically in the last stage of 4-stage charging. It
can also be switched on manually by pressing “Function Key” upon battery connection.
Maintenance mode automatically shuts down after 36 hours of operation to avoid overheating.
Maintenance charging mode functions
1. Battery voltage maintenance
During cold weathers batteries have lower power output & engine cranking requires twice
as more current than normal. Batteries with lower charge rate tends to ignition failure.
Maintenance mode helps keep batteries in optimum condition ready for instant engine
ignition and use.
2. Improves battery chargeability
For batteries that remain unchargeable after Reinforced Activation Mode, might be in poor
condition due to over draining or sulfation lead to charging failure, showing Er1, Er2 or Er3
on the indicator. Manually switch on Maintenance Charging Mode to charges up the battery
slowly and safely , preparing it for normal 4-stage charging to it’s maximum capacity.
Remark: Discontinue charging when battery housing temperature reaches or above 45-50˚C.

Microprocessor monitors battery condition during charges for :
•Real-time battery voltage hold status
•Real-time battery charge percentage (%)
•Real time indication of failure occurrence during charges
Status information can be easily monitored through the 7 segment display and the LED
signals.
10
Real-time charging status helps users
monitor charge status in both voltage
holding and charge percentage.
Battery capacity level in % with 10%
increment from 10 to 90% and FUL
(i.e. 100%)
Error codes are shown on the
indicator when failures occur during
charging process. Refer to the Error
Code chart for further details (as in
the right table and manual).
