1. Product Introducon
ATEK 4000 is a smart charger based on the PWM high frequency switching
ower supply (AC-DC) technology and MCU (with 12bit ADC) control, featuring high
efficiency, low loss, small size, light weight, LCD display interface, and complete
protection function. It is the best choice for car, home and industrial battery charging
and has the following features:
Identify 6V/12V batteries automatically.
Adopt 4-stage smart charging principle: pre-charge constant current
constant voltage float charge;
Four charging modes are available: 6V/1A (slow), 12V/1A (slow), 12V/4A
(fast), 12V/4A (low temperature)
LCD display: analog graph, figure & character display, ensuring more
intuitive, clear and simplified operation;
Wrong battery prompt, reverse polarity prompt and protection, over
temperature protection, power-down memory, short circuit protection,
Separate button is available to select charging mode.

3. Charging Features and Electrical Parameters
This product provides a 4-stage charging mode: pre-charge, constant current, constant voltage, and float charge, and
the features are as follows:
i) Pre-charge: idenfy the baery voltage before charging; if the baery voltage is lower than the reference
voltage, the baery will be pre-charged in order to avoid damage to the baery.
ii) Constant current: the main charging phase; the baery will be charged with the maximum current, 70%~85%
of the electricity is charged in this stage
iii) Constant voltage: in the process of constant voltage charging, the baery voltage will be higher and higher,
and the current will be smaller and smaller; when the charging current drops to 0.5C, the constant voltage
charging ends, and then enters next stage; the constant voltage charging stage is the boost charge, and the
baery is almost fully charged at the end of the stage;
iv) Float charge: it is a maintenance charge, and allows for a longer me of safe charge. Through trickle charge,
the baery can be charged to nearly 100%. Too small current is insufficient to cover the self-discharge of the
baery, and too large current will lead to over-charge and dehydraon. Long me charging with a small
current can eliminate the vulcanizaon of the negave electrode plate.

1) Power-down memory funcon: in the charging process (constant current and follow-up stage), the product can
remember the current charging mode aer power outage, and restores the original state when the grid resumes; the
maximum me is 12h with baery connecon.

2) Charging mode: idenfy 6V/12V baeries automacally; for 6V baeries, only 6V/1A SLOW mode is available; for
12V baeries, three charging modes are available, as follows:
6V 1A /SLOW charging mode (default)
12V 1A /SLOW charging mode
12V 4A /FAST charging mode
12V 4A /LOW TEMP charging mode (Environment temperature <10 )
The minimum voltages for automac idenficaon of 6V&12V baeries are 3V and 7.4V respecvely.
3) Protecon:
Short circuit protecon: keep or return to the inializaon interface.
Reverse polarity protecon: the LCD displays reverse polarity signal
Overheang protecon
IP65 dustproof and waterproof
4) LCD display funcon
The product integrates LCD, as shown in Fig. 2. It displays the analog baery status, charging mode, charging state,
real-me voltage, and error message, and integrates LED indicators. The specific LCD states are shown in Fig. 4
below:
Remark: i) 6V: When the baery voltage is between 3.5V 5V, the charger will work at 6V/Slow mode. LCD flashes the
real me baery voltage at 1Hz frequency and the baery icon scrolls. Press the buon to pause/resume the
charging process. The baery icon stops scrol

Precauons and Operang Instrucons
1) Precauons:
a. The supply voltage of the product is 220~240VAC; please make sure that the mains voltage meets the
specificaons of the product before using;
b. The charger is suitable for 6V/12V regular and Gel baeries with 5Ah ~ 120Ah capacity;
c. Clamp the baery anode with the red clip of the output line, and clamp the cathode with the black clip; it will
report error if the polarity is reverse;
d. The working environment of the product is 0°C~40°C; do not use beyond this range of temperature;
e. Before charging the baery, in order to prevent the equipment connected to the baery from damage or
unnecessary influence, disconnect the baery and the equipment before charging the baery;
2) Operang instrucons:
A. Connecon and reverse polarity: select the baery to be charged, confirm the input voltage and then insert the
power plug, enter into the inializaon interface as follows Fig. 7; clamp the red clip of the output side to the anode
of the baery, and clamp the black clip to the cathode; if the polarity is reverse, the red (Fault) LED flashes at 1Hz,
and LCD displays as shown in Fig. 8

B. Pre-charge, constant current & constant voltage charging: clamp the output terminal to the baery to idenfy 6V
or 12V baery; for 6V baery, it will start charging in 6V/slow mode immediately; for 12V baery, it enters 12V/slow
mode by default; you can press the MODE buon to switch among the three modes sequenally(Slow/Fast/Low
Temp), each me you press the buon, the backlight is turned on for 10 seconds; the display effect is shown in Fig. 9;

C. Float charge: enter the float charging state, the baery icon shows full, and the real-me voltage and FUL
characters display alternately at 1Hz frequency.
buon; no mode selecon is possible during the float charge, as shown in Fig. 10 below:
Fig. 10
D. Power-down memory: in the charging process, unplug the power plug or in case of power outage, the product will
save the original charging mode as long as the baery voltage exceeds 5V; the LCD but
the maximum memory me is 12 hours; when the power resumes, it will
connue to charge in the original state;
E. Charging completes: unplug the power plug, and then remove the clips from the baery.
