- Q:What are the technical parameters of the battery?
- Battery capacity is defined as ∫ t0tdt, theoretically t can be infinite, but in fact when the battery discharge is lower than the termination voltage continues to discharge, which may damage the battery, so t value is limited, the battery industry, in hours (h) Battery sustainable discharge time, feel the C24, C20, C10, C8, C3, C1 and other nominal capacity value.
- 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:How does battery activation work?
- If the battery is charged, because the battery discharge itself, the active substance to activate, not add acid, but should be added pure water (no minerals and impurities in the water) is best steaming water, and now you Since the addition, you can use water to wash several times, and then use 1C current charge to 2.3 times. Then discharge, so repeated several times, will be better. So that you can remove the vulcanization.
- Q:What is the meaning of the battery above 12v65Ah?
- 12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)
- Q:How to deal with waste batteries?
- The rest of the various types of waste batteries are generally shipped to a special toxic, hazardous landfill, but this approach not only cost too much but also cause waste, because there are many useful raw materials available.
- 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:How should the battery be well maintained?
- Electrolyte density This is to evaluate whether the battery charge is normal, whether the aging of the important parameters, the use of density meter or electrolyte density tester can be measured. If the electrolyte density is too small, you need to charge. And the electrolyte concentration is too thick or too thin to a certain extent, it means that such as the occurrence of plate vulcanization, short circuit or overcharge phenomenon, this time on the need for maintenance.
- Q:Lead-acid battery how to maintain?
- After 5 hours of repair, the excess electrolyte is sucked out with a straw, and if the electrolyte is sucked out into black, it indicates that the battery is severely grounded and that the battery is difficult to repair.
- Q:Maintenance-free battery how to detect it?
- Do not always check the color of the electric eye for maintenance-free batteries. Green for the full power; black for the lack of electricity, need to be added to charge; gray or light yellow for the electrolyte is insufficient, because maintenance-free battery can not add liquid, should immediately replace the battery.
- Q:What battery does the van use?
- General use of lead-acid batteries. Electrode is mainly made of lead and its oxide, the electrolyte is a sulfuric acid solution of a battery. English: Lead-acid battery Discharge state, the main component of the cathode is lead dioxide, the main component of the negative lead; charge state, the main components of the positive and negative are lead sulfate. Divided into exhausted batteries and maintenance-free lead-acid batteries.
