12V/40A Lead-acid Battery Charger
2. Application Scopes:The charger are widely used for charging sealed lead-acid batteries, flooded lead-acid batteries and gel lead-acid batteries of electromobile, electric forklift, electric vehicles, electric motorcycles, electric sweepers, electric boats, electric sightseeing cars, electric golf cart, electric tractor, electric lift trucks, electric medical equipment, electric transportation trucks.
3. Product Advantage1) High efficiency, small size, light weight: The charger is with over 90% efficiency. Proper structure as well as nice thermal design make the charger small and light with good portability.
2) Advanced technologies: Switching power supply type and MCU controlled 4 stages charging technologies can supervise the whole charging process and let the battery under best electrochemical reaction status, control the temperature rise and threshold voltage, that avoid overcharge or underfill, reduce gas evolution and water loss, prevent battery polarization, vulcanization and thermorunaway, extend the battery service life.
3) Exclusive precharge mode supplies activate, repair and prolonging life functions for long-term unused or deep sleep batteries.
4) High reliability: The charger is made of high quality military and industrial levels components. Advanced circuit design and strict production process according to ISO9001: 2008 quality management system make the charger with low reject rate, high reliability and long service life.
5) The charger is reliable with multiple protections, such as over temperature protection, output short-circuit protection, reverse polarity protection, output over-voltage protection, battery failure protection, that prevent damage by faulty operations.
6) The charger case is made of aluminum alloy with surface oxidation treatment, high-grade, fashion, good heat dissipation ability, high hardness, antioxidative, non-fading.
4. Charging Mode:1) Precharge stage (T1): When the battery voltage is lower than normal standard, the charger can not withstand large current charging. The charger will supply small current for charging, which has the functions of activation, repair and battery life extension. When the output voltage reach normal value or at the T1 of the timing period, the charger will switch to fast charge stage automatically.
