FAQ


What is sulfation of batteries?

Sulfation is the formation or deposit of lead sulfate on the surface and in the pores of the active material of the batteries' lead plates. If the sulfation becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all. Common causes of battery sulfation are standing a long time in a discharged condition, operating at excessive temperatures, and prolonged under or over charging.

How long a battery can last?

The service design life of a battery are vary considerably with how it is used, how it is maintained and charged, temperature, and other factors.

Do batteries self-discharge when not in use?

All batteries, regardless of their chemistry, self-discharge. The rate of self-discharge depends both on the type of battery and the storage temperature the batteries are exposed to. However, for a good estimate, Narada batteries self-discharge approximately 4% per week at 80ĄăF.

How can I evaluate the health and charge state of a battery?

Routine battery examinations divulge irregularities in the charging system as well as in the batteries. The principle method is to examine the electrochemistry of the battery through hydrometric electrolyte inspection. As previously discussed, this important examination cannot be accomplished with sealed absorption or gel batteries. Voltage readings alone require experience to interpret. Hydrometric readings will uncover early warnings of overcharging or overdischarging before batteries are damaged. The state-of-charge and reliability of a lead acid battery can best be determined by the specific gravity of the electrolyte measured directly with a common bulb-type hydrometer with a glass float. We do not recommend the ball float type hydrometer. Specific gravity is a unit of measurement for determining the sulfuric acid content of the electrolyte. The recommended fully charged specific gravity of marine batteries is 1.255 to 1.265 taken at 80ĄăC More than .025 spread in readings between fully charged cells indicates that the battery may need an equalization charge. If this condition persists, the cell is failing and the battery should be replaced. Since water has a value of 1.000, electrolyte with a specific gravity of 1.260 means it is 1.260 times heavier than pure water while pure concentrated sulfuric acid has a specific gravity of 1.835.

Q:How should the battery be well maintained?
Battery Pile The battery pile head is part of the battery connected to the vehicle. If the corrosion or poor connection occurs, the battery will work poorly. The owner can check whether there is a white powder near the pile head, which is the sign of the pile head corrosion. If the white powder is more, you can use boiling water to burn it off, and then its anti-corrosion treatment, in the pile head smear some grease or preservatives can, but should not be too much to apply, so as not to affect the use.
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: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?
If you are talking about dry batteries, that is, to add sulfuric acid can use the battery (commonly known as water bottles), then it is because the long-term storage so that a high degree of oxidation of the negative board, plus acid will be a high temperature, Low, you can add acid in the pool after the addition of a small current for a long time to charge, you can solve. Generally with 0.05C charge to 3 times can be.
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:What are the hazards of battery over discharge?
The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.
Q:What are the technical parameters of the battery?
Usually the capacity of the power supply is expressed by kV · A or kW. However, as a power supply VRLA battery, the use of security (A · h) that its capacity is more accurate.
Q:How to deal with waste batteries?
Laboratory recycling method: ordinary dry battery is cylindrical, the outer cylinder made of zinc, the zinc cylinder is the battery negative; tube central carbon rod for the positive; tube for the manganese dioxide, ammonium chloride and chlorination Zinc.
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?
Battery is widely used, can be used for ups, electric cars, scooters, cars, wind energy solar systems, security, and so on.
