III. Working modes
Constant current mode: when battery voltage is lower than charger preset voltage,
the working mode is constant current charging mode, where constant charging current
is provided by the charger to battery. In this mode, both battery and charger are under
Constant voltage mode: Adoption of pulse width modulation (PWM) can have precise
control of charging current and output voltage so that the battery can be fully charged while
at the same time not over-charged.
Trickle mode: When battery voltage decreases to preset value, charging current will
decrease gradually to preset value, and the charger will go into trickle floating charging mode
from either constant current mode or constant voltage mode. Even if charging is completed,
battery can still be set in floating charging mode.
IV. Multiple protections
Overheat protection: The charger will close automatically without current output for protective
purpose when its temperature is over 105℃, and when the temperature is decreased below about
80℃ or power supply is shut down for 10 minutes, charging process can be resumed.
Short circuit protection: In case of accidental short circuit, the charger will close automatically
without current output, and beep for alarming. Once correctly connected, charging process will be
Reverse connection protection: Whenever positive poles and negative poles of the charger
and the battery are not connected correctly, the charger will close automatically without current
output, and beep for alarming. Once correctly connected, charging process will be resumed.
Low voltage protection: When single cell voltage is below 1.5V, the charger can not be
started up, and beep for alarming. This mechanism is to avoid possible damages caused up
by voltage discrepancy between the battery and the charger.
1. Dangerous high voltage is contained inside the charger, so please contact your local dealer
or the manufacturer in case of equipment failure.
2. Do not use under humidity or high temperature, or where there are flammables or explosives.
3. Do not block cooling hole, or use the charger while cooling fan is stopped.
4. Do prevent rain or water entry into the machine to avoid damages.
5. Non-professional technicians are strictly prohibited to open the machine or change its purpose.
Otherwise, severe injury may be caused.
VI. Charging operation
Step 1, Examine and make sure rated voltage of battery is conforming to output voltage of charger.
Step 2, Connect correctly the charger and the battery.
Step 3, Examine and make sure mains supply voltage is conforming to input voltage of the charger.
Step 4, Connect mains supply and the battery, watch to see if the indicator is on and the cooling
fan is working when charging.
Step 5, if the charger refuse to work, turn off mains supply immediately and check all the
connecting cables between mains supply, the battery and the charger.
VII. Warm Notice
For the purpose of a longer service life, avoid charging your battery after it is completely
consumed. And, it is always good to charge and discharge this leadacid battery frequently.
If a 12V battery is consumed up (below 10V), firstly the battery will be damaged greatly,
and secondly the charger will also be protected due to overcurrent. This indicates that your
battery is below 10V, which is a severe power insufficiency. Do pay attention next time when
you using the battery!

Question 1: Does the float voltage and equal voltage can be adjust by the end user?
Yes, it can adjustable. But only can adjust within the factory set adjustable voltage value + / - 2 v
lif customers need special charge and float charge voltage value of the best order and sales confirmation before,
we will according to the actual situation before out of factory
Question2: What is the charging process of full auto battery charger
Firstly it start charging the battery in state of constant current, when the voltage rises to the Equal Charging
Voltage., Will transfer automatically to charge the battery with constant voltage.
When the battery is filled gradually, charging current will automatically go down,
down to the 1 / 5 of rated charging current will automatically switch to float voltage to charge the battery until full.
Question 3; can you manufacture multiplex voltage charger?
we can manufacture double voltage charger only
Such as 12 VDC to 24 VDC 30 a. 12 VDC to 24 VDC 40 a. 24 VDC 36 VDC 25 a
Other voltage needs can be customized
Question 4 : does your charger with any certification ?
Answer As all the charger specification is customize base on customer request , so we did not apply any certification for charger
Question 5: how to choose the right model charger ?
Under normal circumstances, we recommend the use of 10% of battery capacity current to charge the battery will be much better
For example, 48 VDC 200 ah battery, so we suggest to buy 48 VDC 20 a charger,
it can be full charge after 10 hours and this is the most ideal choice.
As if use too much current to charge the battery , it may shorten the battery nature life or damage the battery
