San Yang 12V65AH battery factory direct calculation method Shengyang battery 12V65AH battery charging current? Normal charging current ÷ 10 = battery capacity, such as a battery capacity of 1500mAh, it's normal charging current is 1500 ÷ 10 = 150mA. Normal full charge time is 12 to 14 hours. Car battery charging current is how much? If your car battery charging in the car on the car charging that the current is changing, then the constant 14V, the charging current and the power shortage situation concerning your battery, power shortage The more current is greater. Now the general car battery trickle charge generally do not win, but if you are often open a short distance, every time I drive less than 10 minutes, start the car because power consumption is very large, it would have to regularly test battery power , win supplement charge, or regular run at high speed, went out to play next. If removed from the car supplement charge, generally divided into two phases, the first charging current is 0.1C20,10-12 hours, the second phase 0.05C20,2-3 hours. C20 is the rated capacity, the battery is like above 60Ah like. How to control the battery charging current size? General battery charging current is more difficult to control. Because the battery during the charging process the resistance is varied, so if constant current charging voltage will change, then, the battery is not necessarily good. Further design and complex, the cost is high. So now most of the charging equipment are used to adjust the voltage regulator such as the automobile generator and charging machines. Of course, the current will change, but not because of the late charge affect battery life. Difficulties San Yang battery capacity test technology for the analysis of the current situation, battery manufacturers, battery testing technology research institutions, as well as the majority of battery maintenance staff, are actively exploring a fast, accurate, reliable, and safe battery test technology . Especially for the majority of on-site maintenance engineers, this need is even more urgent. Unfortunately, the battery is a very complicated device to achieve the conversion between the chemical and electrical energy. Discharge of a battery is a process of chemical energy into electrical energy, the battery charging process is the conversion of electrical energy into chemical energy in the process. From electrochemical point of view, can not provide more information for the user inside. San Yang battery sealed lead-acid battery capacity quick test Technical Difficulties Analysis 1.1 check discharge method to check discharge method that is 100% C in the depth of discharge, it has the capacity to test the advantages of accurate and reliable, therefore, is still the world's most reliable detection of battery performance Methods. Check discharge method that full discharge capacity of the test is to test the battery capacity of the most direct and most reliable method, whether online or offline detection, backup power must be set as a precautionary measure to ensure the safety of the system. 1, San Yang batteries together to depict the common seal against leakage selection skills to ensure that no arbitrary placement leak. Can be safely used in various devices (Shi) 2, San Yang battery separators strong adsorption function excellent choice AGM separator, electrolyte completely absorbed in the plates and separators, eat-band no free electrolyte. 3, San Yang battery gas compound rate battery FM common layout ensure gas sealing compound rate of more than 99% to reach 4, San Yang battery grid FM lead batteries use aluminum grid, ensuring excellent function extends battery float together charge status using or recycling use, even tho number use under deep cycle conditions. 5, Union UPS battery cycle / life expectancy under normal conditions the float, FM batteries can reach more than 1000 charge-discharge cycles, the situation in the float can use 5-7 years, the number of series and longevity up to 15 years. 6, San Yang battery self-discharge is low, the number of long storage life at 20 ℃, FM battery self-discharge rate does not exceed 3% / month in storage conditions, FM battery compartment just charge it 6-9 months 7 Union UPS battery deep discharge recovery to strong
