1、The charging power supply will automatically stop after it is fully charged to avoid damage to the battery due to overcharging. 2、After fully charged, the 240V power supply is automatically turned off, and the monitoring mode is entered. After the battery voltage drops, the charging is automatically started. 3、Exhibition hall mode, can keep the battery fully charged and extend its service life without turning off the power for a long time. 4、Reverse connection, overload, over current, and other multiple protections, no current start, no sparks, disconnect the connection and automatically turn off the output. 5、Using variable frequency control power chip, high efficiency, energy saving and stability; high frequency high and low voltage isolation transformer, safe and reliable. 6、Over‑discharged battery, when the voltage is lower than 11V, it will automatically enter the activation repair mode, and after the voltage is increased, it will automatically switch to the normal charging mode. 7、After fully charged, the battery performance is displayed: 1, 2, 3, 4 (excellent, good, medium, poor). Identify batteries that should be scrapped and display the prompt: L, avoiding long‑term overcharging causing danger and waste. 8、Suitable for charging batteries in maintenance workshops, for monitoringof exhibition hall mode, car decorating and vehicles parked for a long time. Item Type: Fully Automatic Battery Charger Material: Aluminium AlloyScope of Application: 1. Ordinary maintenance-free battery 2. Flat-type AGM battery; 3. Wrap type AGM battery; 4. EFB start-stop battery; 5. Batteries for ships; 6. GEL battery 7. Batteries with a capacity of less than 200Ah of 12V specifications such as UPS batteries Input Power: AC240V/50Hz Maximum Output Power: 320W Maximum Charging Current: 25A Size: Approx. 246 x 75 x108mm/9.69 x 2.95 x 4.25in (length x width x height) Working Temperature: 0-45℃ Introduction to battery charging knowledge Most of the batteries equipped on cars are 12V batteries, including the most common maintenance-free batteries, AGM, EFB start-stop batteries, etc. Its characteristic is that it can discharge with high current in a short time, which is suitable for starting power supply of automobile, but it is not suitable for deep discharge. After discharging, it should be recharged in time. If it loses power for a long time, the electrode plate will age, reduce its capacity and service life, or even scrap it. Special Note Brief introduction of multifunctional intelligent charging monitoring power supply function How to Use: Please connect the charging center to the battery The charging indicator will light up in cycles, and then flash to indicate the current charging progress The charging indicators will all flash, indicating that the charging is complete. Error Message Special Note During charging, if you want to disconnect the battery clip from the battery, you need to turn off the power first, and then operate after the device display off to avoid short circuit of the output positive and negative poles. In the exhibition hall monitoring mode (when 1, 2, 3, 4 are displayed in the display area of A), the battery clamp can be directly disconnected. In this mode, the display will not off when the power is turned off.Note: Before using the equipment, read the instruction manual carefully. When working, the vents on both sides of the equipment should be kept unblocked to prevent foreign objects (especially metal foreign objects) from falling into or being sucked into the vents, so as to avoid short circuits and damage the equipment. Use it indoors only, and ensure good ventilation. Do not place it in rain or snow. Do not use this instrument in a car or under the hood of a car. Replace the power cord with original accessories. Do not use this instrument to charge non‑rechargeable batteries. Disconnect the machine from the power grid when installing, overhauling, and maintaining the machine. If the equipment fails, please contact the dealer or the manufacturer, and the user shall not disassemble it by himself. Safety warning During the charging process, the battery may produce explosive gas. The surrounding area should be well ventilated to avoid sparks and do not smoke. Before using the equipment, people with no experience and untrained need to receive guidance before using it. If the device is impacted and the casing is deformed, it is strictly prohibited to continue using it. Due to the deformation of the shell, the internal circuit may be short‑circuited, and the shell may become charged. Continued use may cause serious damage to the equipment or cause personal danger. Regularly check whether the power cord and output cord are damaged. If they are damaged, they can no longer be used, and the original parts must be replaced. 1 x Fully Automatic Battery Charger
