Incorrectly exposed current or ignoring indicators on the control panel charger Ermak often lead to boiling of the electrolyte and sulfation of the plates, which requires immediate adjustment of settings. If you have just purchased this device or faced problems when charging the battery, you need to know exactly the functionality of a particular model, since the algorithms of operation can differ significantly from older transformer analogues. In this manual, we will analyze the step-by-step connection process, decipher error codes and determine methods for safely restoring car batteries.
Modern models ERMAK They are equipped with microprocessor control, which automatically adjusts the parameters depending on the state of the battery. However, automation requires proper initial setup by the user, especially if the battery is deeply discharged or has a non-standard capacity. Ignoring basic operating rules, such as the order of connection of terminals or the choice of desulfation mode, can lead to failure of both the charger and the expensive battery.
To get started, make sure you hold the model you are looking for, as the line includes devices with different voltages and currents. Proper operation charger extends the battery life and ensures a confident start of the engine in winter. Next, we will consider in detail the technical characteristics, preparation stages and algorithms for troubleshooting.
Technical characteristics and features of Ermak models
Line of chargers under the brand Ermak It covers a wide range of needs, from charging motorcycle batteries to servicing powerful truck batteries. The basis of the design of most models is the impulse principle of voltage conversion, which makes the devices compact, light and protected from overheating. Unlike heavy transformer analogues, these devices are able to operate in a wide range of input voltage, which is important for garage conditions with unstable power grid.
The key feature is the presence of built-in microprocessorIt controls the entire charging cycle. It automatically switches modes, preventing the electrolyte from overcharging and boiling. Many models support the desulfation function, allowing the capacity of old batteries to be restored by supplying pulsed currents. Also an important parameter is the availability of protection against overpole, short circuit and overheating, which makes operation safe even for inexperienced users.
Below is a comparison table of popular models so you can identify the capabilities of your device:
| Model | ACB voltage (B) | Charge current (A) | Type of management |
|---|---|---|---|
| Ermak 12B 6A | 12 | 6 | Automatic. |
| ERMAK 12/24B 10A | 12/24 | 10 | Microprocessor |
| Ermak 12B 4A | 12 | 4 | Automatic. |
| Ermak Pro 20a | 12/24 | 20 | Programmable |
When choosing a mode of operation, always focus on the capacity of your battery. Too high current can damage the plates, and too low - will not allow charging the battery in a reasonable time. Optimal is considered to be the current, which is 10% of the battery capacity.
Charging preparation and safety measures
Before you plug in charger To the network, it is necessary to conduct a visual inspection of the battery and the device itself. The battery body should not have cracks or traces of electrolyte leakage, and the terminals should be cleaned of oxides to ensure reliable contact. If there is a strong plaque on the battery, it should be removed with a metal brush or soda solution, after which dry with rags.
It is important to remember the sequence of actions when connecting. First, the "crocodiles" or clamps are connected to the battery terminals: red wire to plus (+), black to minus (-). Only after that, the power cord is inserted into the 220V outlet. Disruption of this sequence can cause sparking, which is especially dangerous near the acid vapors released by the battery.
⚠️ Attention: It is strictly forbidden to connect the charger to the network if the terminals are not connected to the battery or are connected to each other. This can cause the electronics to fail instantly.
Provide good ventilation in the room where the charging takes place. In the process of electrolysis, a rattleswept gas is released, which in a mixture with air forms an explosive mixture. Do not smoke or use an open flame in the vicinity of the device being charged. It is also recommended to remove the tightly seated terminals from the car or completely remove the battery if charging is done in winter in a warm room.
Step-by-step instruction for operation
Charging process on devices ERMAK It is automated as much as possible, but requires the right choice of parameters. After connecting the terminals and turning on the network, the current battery voltage will be displayed on the display or LED panel. If the voltage is below 3-4 volts, many smart charging systems may not start the process automatically, considering the battery to be faulty or imperceptible.
In such cases, the forced start mode or the severely discharged battery mode should be activated if it is provided by the model. This often requires pressing and holding the appropriate button on the control panel. After the voltage rises to the operating level, the device will go into the main charging mode.
☑️ Checklist before launch
In the process of operation, the device will independently regulate the current strength. As the battery is filled with energy, the current will decrease and the voltage will increase. When the charge reaches 100%, the device will switch to storage mode (100 percent or Float), maintaining the charge with low current and compensating for self-discharge. This allows you to leave the battery connected for a long time without the risk of overcharging.
If your model has a manual mode, you can set the voltage and current yourself. In this case, the control of the process falls on your shoulders: you must periodically check the temperature of the battery body and prevent it from heating above 45 degrees Celsius. When heated, the charge should be suspended until cooling.
Operational and recovery functions
Modern. charger Ermak They offer not just direct current, but complex recovery algorithms. The desulphation regime is one of the most demanded. Sulfation is the process of forming large-crystalline lead sulfate on plates, which reduces capacity and increases the internal resistance of the battery.
The desulphation algorithm works by supplying short pulses of high-amplitude current, alternating with pauses. This allows the sulfate crystals to break down, returning the active mass to a working state. This process can take from several hours to several days, depending on the degree of neglect of the battery.
How the pulse mode works
Pulse charge mode prevents the active substance from settling to the bottom of the battery bank. Short powerful pulses loosen the mass on the plates, providing a more uniform distribution of electrolyte density and increasing the final battery capacity.
For AGM and GEL batteries, which are sealed and sensitive to overcharging, special modes with limited voltage are provided (usually up to 14.4V or 14.7V). Using the standard mode for such batteries can lead to depressurization of the valves and irreversible damage.
Some models support the "Supply" or "Power supply" mode. In this mode, the device operates as a source of stable voltage 12V or 24V, which allows you to replace the battery during diagnostic work or replacement of car parts, without resetting the settings of electronic control units.
Decoding of indicators and error codes
Diagnosis of malfunctions is carried out through an LED indication or a digital display. Understanding the device signals allows you to quickly identify the problem. For example, a flashing "Error" indicator or code Er1 most often indicates a short circuit at the terminals or an attempt to charge a faulty battery with an internal circuit.
If the overheat indicator is on, the device automatically lowered the current or stopped charging until the components cooled. This is a normal situation when working at maximum currents in a hot room. The code indicating reverse polarity will light up immediately after you connect if you have confused plus and minus – in this case, the device will not turn on until you fix the connection.
⚠️ Warning: If the device shows a connection error to a serviceable battery, try to clean the terminals or connect another charged battery in parallel for a few minutes to raise the voltage to a detectable level.
Digital models can display current voltage, charge current and percentage of charge in real time. This allows you to accurately control the process and turn off the battery in time if it suddenly began to behave abnormally (for example, a sharp jump in voltage or no voltage growth at high current).
Expert advice: When charging old batteries, the voltage can “stuck” at a certain level, and the current does not fall. This is a sign of strong sulfation or short circuit in one of the jars. Continuing to charge in this mode is dangerous.
Maintenance and storage of the device
For durability ERMAK Simple storage rules must be followed. The device must be in a dry room protected from direct sunlight and dust. Ventilation holes on the body should be periodically cleaned of dust with compressed air or a soft brush, so as not to disturb the heat sink.
Power wires and clamping cables should not be reeled too tightly or broken, as this can damage the internal insulation and lead to short circuit. When stored in a winter unheated garage before turning on, let the device warm up to room temperature to avoid condensation inside the electronics.
Regularly check the condition of the clamps ("crocodile"). The springs should be elastic, and the teeth should be sharp and clean. The oxidized contacts create resistance that warms the connection and reduces charging efficiency. If necessary, the clamps can be disassembled and cleaned contact areas.
The main conclusion: The Ermak charger is a reliable tool that, when used correctly, is able not only to charge, but also to extend the life of your batteries thanks to smart recovery algorithms.
Frequently Asked Questions (FAQ)
Can lithium batteries (LiFePO4) be charged with the Yermak device?
Most of the models of Ermak are designed for lead-acid batteries (WET, AGM, GEL). Charging lithium batteries requires strict control of the voltage on each cell and a special algorithm that conventional charging does not provide. Using the standard mode can cause the lithium battery to ignite. Use only Li-ion-labeled models or universal chargers with a selectable chemical composition.
Why doesn’t the device see the battery and start charging?
Most likely, the voltage at the battery terminals fell below the detection threshold (usually below 2-3 volts). In this case, the battery is considered to be missing or malfunctioning. Try to connect a serviceable charged battery in parallel for 5-10 minutes to raise the total voltage, after which the main mode will start. Also check the reliability of the contact clamps.
How long does the battery need to be charged?
The charging time depends on the battery capacity and the degree of its discharge. At a current of 10% of the capacity (for example, 6A for 60Ah), a full charge of a deeply discharged battery can take 10-12 hours. Smart charging will determine the end of the process and go into storage mode.
Can I use Yermak as a power supply for auto electric cars?
Yes, if your model supports Power Supply mode. In this mode, the device produces a stable voltage without reference to the state of the battery. This is convenient for setting up alarms, replacing batteries in security systems or diagnosing electrical equipment without the risk of discharge of a regular battery.
