Q:How to repair the battery?
Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
Q:Battery 200ah / 104 what does that mean?
2V battery capacity (from 200AH-3000AH have) long design, good stability, the price is also expensive; 12V battery capacity is generally the largest 250AH, design life as 2V, price economy, high current discharge better.
Q:What battery does the van use?
The most obvious feature of lead-acid batteries is the top of the plastic cover can be unscrewed, there are ventilation holes above. These fillers are used to fill pure water, check the electrolyte and the use of exhaust gas. In theory, lead-acid batteries need to check the density of each electrolyte and the level of liquid, if there is a need to add distilled water. But with the upgrading of battery manufacturing technology, lead-acid battery development for the lead-acid maintenance-free batteries and colloidal maintenance-free batteries, lead-acid batteries do not need to add electrolyte or distilled water. Mainly the use of positive electrode to produce oxygen can be absorbed in the negative oxygen cycle, to prevent water reduction. Lead-acid water batteries are mostly used in tractors, tricycles, car start, etc., and maintenance-free lead-acid battery wider range of applications, including uninterruptible power supply, electric vehicle power, electric bicycle batteries. Lead-acid batteries according to the application needs to be divided into constant current discharge (such as uninterruptible power supply) and instantaneous discharge (such as car to start the battery).
Q:The role of the battery?
It filled with lead plate filled with sponge lead as a negative electrode, filled with lead dioxide lead dioxide as a positive electrode, and with 22 to 28% dilute sulfuric acid as electrolyte. In the charge, the electrical energy into chemical energy, the discharge of chemical energy and into electrical energy.
Q:What is the meaning of the battery above 12v65Ah?
12V represents the rated voltage. 65Ah indicates that the battery capacity (ie 1 ampere current can be used for 65 hours).
Q:How does the battery increase the voltage?
With the same battery pack in series; if the required current is relatively small, you can use DC-DC module.
Q:What are the advantages of maintenance-free batteries?
The advantage of a maintenance-free battery is that the service life is twice as long as the dry battery! And in the use of the process without maintenance! The voltage is also relatively stable.
Q:What are the hazards of battery over discharge?
Crystalline conductivity is poor, and bulky, will clog the pores of the battery plate, affecting the battery electrolyte penetration and exchange, but also further increase the battery resistance, a long time will prevent the battery power and chemical energy Of the reversible conversion, resulting in poor recovery of the battery charge, the battery was seriously damaged, or even unable to repair until scrapped.
Q:How to deal with waste batteries?
In addition to lead-acid batteries, all kinds of batteries are dissolved in sulfuric acid, and then by means of ion resin from the solution to extract a variety of metals, raw materials obtained in this way than the heat treatment method is pure, so the market price is higher, and the battery contains 95% of the various substances can be extracted.
Q:80ah how much battery storage capacity?
The size of the battery storage power refers to the battery capacity. Battery capacity is generally calculated in AH (safety). You 80Ah battery capacity is 80Ah, meaning that if you discharge current to 80A, you can put an hour.
