- Q: How to repair the battery?
- Connect the positive and negative output of the repair instrument to the positive and negative pole of the battery, open the repair instrument, repair the battery. The first repair time should be no less than 48 hours.
- Q: What is the difference between a maintenance-free battery and a conventional battery?
- Lead-acid battery is composed of positive and negative plates, partitions, shell, electrolyte and wiring pile head and other components, the discharge of the chemical reaction is to rely on positive electrode active substances (lead dioxide and lead) and negative plate active substances (sponge Pure lead) in the electrolyte (dilute sulfuric acid solution) under the action, which plate grid, the traditional battery lead and antimony alloy manufacturing, maintenance-free battery is made of lead calcium alloy, the former with antimony, the latter with calcium, This is the fundamental difference between the two points.
- 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: What are the hazards of battery over discharge?
- When the battery discharge current is large, the heat will become more obvious, there will be serious heat generated when the battery deformation, when the concentration of lead sulfate is particularly large, will form a larger crystal particles, that lead to the battery Internal irreversible sulfation.
- 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: What is the meaning of the battery above 12v65Ah?
- Voltage 12V, current 65AH, that is the capacity of 65A. (A is the unit of current. H is the time unit)
- Q: The role of the battery?
- Battery is widely used, can be used for ups, electric cars, scooters, cars, wind energy solar systems, security, and so on.
- Q: What kind of battery is divided into?
- At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.
- Q: Battery 200ah / 104 what does that mean?
- Lead-acid battery nominal voltage is 2V / (each or monomer), but in fact will be higher than 2V, so the actual use and charging equipment for the matching will use 104, also useful 103, also useful 108 Only.
- Q: How does battery activation work?
- Always keep the battery surface clean. Found that the surface of dust and acid, it should be timely wipe, wipe can be wiped with soda water wipes wipe again, after rinse with water.
