FAQ

Is there a maximum temperature for charging lead acid batteries?

When charging lead acid batteries, the temperature should not exceed 120ĄăF. At this point the battery should be taken off charge and allowed to cool before resuming the charge process.

Are lead acid batteries recyclable?

Lead acid batteries are 100% recyclable. Lead is the most recycled metal in the world today. The plastic containers and covers of old batteries are neutralized, reground and used in the manufacture of new battery cases. The electrolyte can be processed for recycled waste water uses. In some cases, the electrolyte is cleaned and reprocessed and sold as battery grade electrolyte. In other instances, the sulfate content is removed as Ammonia Sulfate and used in fertilizers. The separators are often used as a fuel source for the recycling process.

What is battery cycle life?

One cycle of a battery is a discharge from full charge to full discharge and a return to full charge again. The total number of cycles a battery can perform before failure is called its Cycle Life. Moat battery manufacturers will not discus the Cycle Life of their product. Many advertised Deep Cycle batteries have not been tested, or, which is the case with cranking batteries, were never designed for long Cycle Life .

Q:What is the difference between a maintenance-free battery and a conventional battery?
Different materials will produce a different phenomenon: the traditional battery in the course of the use of the phenomenon of liquid reduction occurs, because the antimony on the grid will pollute the sponge on the negative plate of pure lead, weakened after the full charge of the battery Electromotive force, resulting in excessive decomposition of water, a large number of oxygen and hydrogen, respectively, from the positive and negative plates to escape, so that the electrolyte reduced. With calcium instead of antimony, you can change the fully charged battery back electromotive force, reduce the overcharge current, liquid gasification rate decreases, thereby reducing the loss of electrolyte.
Q:How to determine the battery is good or bad?
If less than 9V but the pointer is in a certain value does not move that the battery is in a state of loss, need to add charge.
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:Maintenance-free battery how to detect it?
Keep the battery surface clean. If the discovery of solid oxide on the pole, it should be timely with hot water pouring, to be removed, so as not to affect the pole and the terminal between the continuity. After cleaning up, wipe the battery surface, in the pole and the terminal cast on the butter to ensure that the pole is not oxidized.
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:What battery does the van use?
The battery is mainly composed of tube positive plate, negative plate, electrolyte, separator, battery compartment, battery cover, pole, injection liquid cover and so on. The electrode of the exhaust type battery is made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is the voltage stability, the price is cheap; the disadvantage is lower than the energy (that is, per kilogram of battery storage power), short life and routine maintenance frequently. Old ordinary battery life of about 2 years, and the need to regularly check the height of the electrolyte and add distilled water. However, with the development of science and technology, lead-acid battery life becomes longer and maintenance is also more simple.
Q:How is the capacity of the battery defined?
General circuit has a battery protection circuit, once the battery voltage is less than 10.8V will automatically cut off the electricity to prevent the battery because of over-discharge and damage. (Nominal value of 12V battery internal six cell grid) with the battery discharge current multiplied by the discharge time to express how much energy the battery can store, is a very image of a measure. The greater the value of the battery, indicating that the battery can store more energy. But does not mean that the battery can use such a large current discharge.
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 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 is a maintenanceable battery?
Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water.
