Seven points to keep in mind about car batteries maintenance

Car battery is important, its function is to provide an electric starter, the engine starting or operating at low speed for the ignition system of motor and other electrical equipment. High-speed operation when the engine when the generator enough, the VGP-BPS8 battery can store excess energy. Unfortunately, it is generally ignored by most people. I do not know the proper maintenance of batteries to keep it plenty of power, is an important part of vehicle maintenance. The following will introduce the conservation of car battery connected to knowledge and common sense, to help you better understands the use and maintenance of the battery to extend battery life.

Car battery car battery works the vast majority of lead acid batteries. In simple terms, it is a chemical energy into electrical energy capable of electrochemical devices. Lead acid battery in the positive and negative plates, bulkheads, shell, etc. electrolyte and wiring trailer hitch and the discharge of chemical reactions depend on the active positive plate (lead dioxide PbO2) and the negative active material (sponge of pure lead, Pb) in the electrolyte (sulfuric acid composition of H2SO4 and H2O water) and as a result. A standard 12V lead-acid VGP-BPS8B battery contains six modules, each of the power of electricity is about 2V (one for each power supply has a positive and negative column: column is entered the positive sign “+”, dark brown negative column when a “-” sign in pale gray).

Traditional batteries will occur in the electrolyte is in decline is because the frame plate door with traditional batteries lead alloy of antimony, antimony will pollute the negative plate of pure lead sponge, weakened after the battery is fully charged in a Counter electromotive force resulting from the decomposition of excess water, a large number of oxygen and hydrogen, respectively, escaped from the positive plate and negative, so the reduction electrolyte.

Without maintenance (maintenance free) batteries into the design principles and traditions of the battery on a coherent strategy, the use of thicker plate materials, important difference is that the plate is consistent with lead calcium alloy. In the electrolysis reaction, it can reduce the flow of excessive burden, reduce the rate of vaporization of liquid, thus reducing the loss of electrolyte, compared to prolong battery life.

Discharge and load

In the year (discharge) process dioxide very edge of lead (positive), the spongy lead (negative), and sulfuric acid electrolyte chemical reaction occurs to produce the discharge of lead sulfate (PbSO 4) and d water (H2O), positive and negative plate the difference between reduced. Because the battery voltage depends on different electrode materials and electrolyte concentration, so the reaction after discharge, the battery loses power. Charging process (charge) and discharge process to the contrary. Current in the generator under the action of sulphate of lead and water lead dioxide (positive), the spongy lead (negative) and sulfuric acid, plates, electrolyte concentration restored, the acer-batcl50l-battery-p-17203.html”>BATCL50L battery of energy.

Caution

1 to start the car every time startup should not exceed 3-5 seconds after starting interval of at least 10 seconds.

2 vehicles often short driving distance open-window open will result in a prolonged state of battery charge less to shorten the lifespan. On the highway driving at a constant rate of 20? 30 minutes, may give enough time to recharge the battery.

3, driving a day before leaving the car, check and ensure that all lights and other electrical appliances (such as radios, CD) has been closed. Because it may drain your battery.

4, if the battery runs out, to ask the fire (Jump-Start, also known as tie-lines) to begin immediately possible a constant speed (such as highway speed) drive at least 20? 30 minutes to fully charge the VGP-BPS11 battery.

5, in the full discharge of the battery case, ask the fire may be unable to help you start your car. In this case, you must use a dedicated battery charger for slow charging.

6, where cars are not long-term investment should first fully charge the car. At the same time every month, launched his car, operation at medium speed for about 20 minutes. Otherwise, place too long, it would be difficult to start.

7 to understand the life of the battery. Using more than 4 years, the recommended replacement.

Mobile phone battery refurbishes technology

Refurbished in recent year’s mobile phone (cell phone refurbished) techniques to restore the VGP-BPS2B battery are as follows:

◆ High-Current Charge: The charge current level, so that large crystals of lead sulfate have a negative wear blocking method of dissolving experiments concluded that the removal of sulfur allowed only a temporary effect, and result in the elimination process of hardening softening increased water loss and the positive plate, causing serious damage to the battery life.

◆ negative pulse: This method has been applied 30 years of history, the principle is to add negative pulse charging process, reducing the BATCL50L battery temperature play a role, but “healing” effect the repair n ‘ is not obvious, the repair rate of 20% is used again, is out of product.

◆ addition of active agents using chemical means for removing lead sulfate crystals, not only the high cost and increase the internal resistance of the battery, and also changed the original structure of the electrolyte, the Use a shorter period of time after repair, the repair rate was approximately 45% or more.

◆ High-frequency pulse: A pulse so that the new weight of crystals of lead sulfate in the form of small crystals, highly reversible electrochemical lead sulfate to enable them to charge properly and perform chemical reactions involved in the repair rate of about 60%, compared to negative pulse effect. However, because of repairs for a long time to take dozens of hours to a week, less effective for severe “healing” in the cell phone batteries can not be repaired, and the technique is simple, there is a number of manufacturers in use.

◆ fix Tandem: Can not accurately judge the performance of each battery, good or bad, the battery charger series overall series with a constant voltage constant current charge of repair, only to play the role of a single charge heal the effectiveness and impact of ill.

◆ time compound resonance (cell phone refurbished): edge control reasonable compensation pulse, the use of pricing in the high order harmonic pulses with a method of large crystals of lead sulfate resonance in the repair process to remove sulfur A1045 battery using this method to repair high performance without having to open the battery cover on the battery less damage, which has significantly extended the life of the battery and broad perspective.

Waking renovation of high-tech mobile phone (cell phone refurbished) battery, the repair rate has reached more than 95% of its capacity to recover up to 70-90% and put aside for a long period can not load a new battery can be awakened sleeping activate your phone is often power? or eat the electric charge obviously did not take long to no electricity, and do not worry, as long as 5 minutes can help you fix the BTP-43D1 battery with a new, as 4-5 days standby.
