The role of the global battery is to store the limited electric energy and use it in the right place.

                Engineers can judge the quality of the battery by measuring the open circuit voltage, taking the 12V battery as an example, if the open circuit voltage is higher than 12.5V, it means that the battery condition is more than 80%, if the open circuit voltage is lower than 125V, it should be immediately added charging, if the open circuit voltage is low. At 12V, it means that the battery stores less than 20% of the electric energy, and the battery can not be used.

                Main features :

                (1) Corrosion-resistant lead-calcium-tin multicomponent alloy high rate discharge electrode excellent self-discharge rate is very low

                (2) ultrafine glass fiber diaphragm suction no harmful gas overflow low temperature performance is superior

                (3) High-strength ABS resin shell and equipment installed at the same place will not pollute the environment

                (4) Fully sealed no leakage without adding water safety valve automatic opening and closing no battery room

                Its working principle is to convert chemical energy into electrical energy, which is widely used in transportation, power, communication and other fields. Each kind of battery will have a self-discharge phenomenon, if not placed for a long time, it will cause energy loss. Therefore, it is necessary to charge and discharge regularly.

                Maintenance-free battery due to the use of absorption electrolyte system, in normal use will not produce any gas, but if the user is not used properly, resulting in overcharging of the battery, it will produce gas, at this time the battery internal pressure will increase, will read the pressure on the battery top open, serious will make the pool bulge, deformation, leakage or even rupture. These phenomena can be judged from the appearance, if you find the above situation should immediately replace the battery.

                The design life of floating charge can reach more than 20 years (20℃). Very small self-discharge current High quality high purity material, less than 4% of the monthly self-discharge current, reduce customer battery maintenance work. Extremely wide operating temperature range can be :20℃~+60℃ temperature conditions, the battery internal resistance is less than the conventional battery, can carry out large current discharge. Reasonable installation and structural design with the new international structure design, easy to install, easy to maintain. Battery charging precautions 1, with a stable standard charging voltage; 2, the battery should be charged and adjusted for a long time without use.

                Comprises a detection tube with a scale and a positioning part for measuring the reference, both ends of the detection tube are open, the positioning part is fixed on the outer wall of the detection tube, the bottom of the positioning part to the lower end of the detection tube is a measurement section, When using the gage for liquid level height verification, only the measuring section of the detection tube is vertically submerged into the electrolyte, and then the end of the detection tube is opened, the detection tube is removed, and the detection tube is removed. It can be read whether the liquid level height value meets the standard requirements of control, and has the advantages of simple structure, convenient detection and high precision in the detection node.

a wide range of applications.

                Grid casting introduction

                Grid is the carrier of active substances, but also conductive fluid collection, ordinary open battery plate shed is generally cast with lead antimony alloy, maintenance-free battery plate shed is generally cast with low antimony alloy or lead calcium alloy, and sealed valve controlled lead-acid battery plate shed is generally cast with lead calcium alloy.

                The first step: According to the type of battery to determine the alloy lead model into the lead furnace heating melting, to meet the process requirements after the lead liquid cast into the metal mold, cooling after the mold is dressed and put,

                The second step: the trimmed grid can be transferred to the next process after a certain aging period.

                The main control parameters of grid are: grid quality; Grid thickness; The integrity of the grid; Grid geometry;

                When charging, the constant force battery should be connected to the external constant current power supply (charging pole or rectifier), so that the material generated by the positive and negative plates after discharge is restored to the original active material, and the external electrical energy is converted into chemical energy storage.

                On the positive plate, under the action of external current, lead sulfate is dissociated into bivalent lead ion (Pb2) and sulfate negative ion (S04-2), because the external power supply continues to absorb electrons from the positive electrode, the free bivalent lead ion (Pb2) near the positive plate continues to release two electrons to supplement, become tetravalent lead ion (Pb4), and continue to react with water. Finally, lead dioxide (PbO2)

is formed on the positive plate. On the negative plate, under the action of external current, lead sulfate is dissociated into the bivalent lead ion Pb2) and the acid-phobic negative ion (S04-2), because the negative electrode continues to obtain electrons from the external power source. The free bivalent lead ion (Pb2) near the negative plate is neutralized into lead (Pb) and attached to the negative plate with velvet lead.

                In the electrolyte, the positive electrode continuously produces free hydrogen ions (H) and sulfate ions (S04-2), and the negative electrode continuously produces sulfate ions (04-2). Under the action of the electric field, the hydrogen ions move to the negative electrode and sulfate ions move to the positive electrode of the battery, forming a current.

At the later stage of charging, electrolytic reaction of water will also occur in the solution under the action of external current.

                Cyclic charge and release usage mode

                1, if the device is connected to the power supply, after charging saturation, it will leave the power supply and be powered by the battery, in this case, it should choose the cyclic charge and discharge mode. .

                2, the high voltage provided by the charger during cyclic charging should be limited: when the ambient temperature is 25℃, the charging voltage of the 2V battery is :2.35-2.45V; The charging voltage of the 4V battery is :470-4.90V; The charging voltage of the 6V battery is 7.05-7.35vThe charging voltage of the 8V battery is 9.40V-9.80V; The charging voltage of A 10V battery is 11.75-12.25V: The charging voltage of a 12V battery is 14.1-14.7V, and the charging current is not greater than 25% of the rated capacity. A.

                3, charge saturation should immediately stop charging, otherwise the battery will be damaged or due to overcharging will easily cause the battery drum.

                4. When charging and discharging, the battery cannot be inverted.

                5, the life of the cycle depends on the depth of each discharge, the greater the depth of discharge, the fewer times the battery can be cycled.

                Lead-acid battery refers to the electrode is mainly made of lead and its oxide, the electrolyte is a sulfuric acid solution of a battery, the battery's positive and negative plates are insulated from each other, no electrolyte can not form a current loop, and the electrolyte is made of non-conductive pure distilled water added to sulfuric acid, distilled water added to become a conductive medium, Only between the positive and negative electrode plates of the battery can the load be accessed in the external circuit to form a complete current loop, and the current can be smooth in the battery, and the current can generate an electrochemical reaction through the electrode plate to charge or discharge. It can be seen that the electrolyte is important to the battery.

                Check and maintain

                Periodic check and maintenance are recommended.

                (1) Measure the total voltage of the whole battery during the floating charge (or current charge) process, such as the charging device output is irregular (or wrong!) 0 reading, be sure to find out the cause of deviation from the normal voltage range, when the total voltage is lower than the normal voltage, the battery reduces the capacity due to insufficient charging, when the total voltage is higher than the normal voltage, the battery loses capacity due to overcharge, and may cause "thermal runaway".

                (2) Check the battery for any abnormal phenomenon, if there is damage (such as cracks, deformation, electrolyte leakage, etc.), you should immediately replace the new battery. Dust should be cleaned up if found. If the abnormal battery continues to be used, there will be a decrease in battery capacity, electrolyte leakage, smoke, and even

will produce an open flame.
