Mainly two things about laptop battery maintenance

Now, people increasingly use the laptop as a laptop, one of the main components of lithium batteries will also increase the problems. So how should make good use of laptop batteries to lithium? Mainly to take two things:

   (1)  An appropriate charge-discharge;

   (2) To minimize the discharge less than the load or discharge. While the Laptop battery is a consumable, lithium-ion is no exception. But nobody wants the durability of the battery, following the battery began to speak. Firstly, to explain who is limited to lithium-ion battery.

The general literature and the country on standard lithium ion lithium-ion batteries on said load current must be between 0.2C to 1C. This is expressed by the load capacity of the battery current, such as your battery is 4AH, then the 0.2C charge current is 0.2 × 4 = 0.8 A, which is the load current must be between 0 8 to 4A.

In general, the charging current to the extent permitted by the smaller the better, rechargeable lithium, ion VGP-BPS2B battery should be the beginning of a constant current charge to IBM R31, for example, the current is 2.8A or more equivalent to 0.7 ° C, is charging circuit to control their own and can not set ourselves.

Although such a charge indicator does not exceed the requirements of the standard, but not relatively significant, especially when the battery capacity decline for some time after the load current may be more than 1C. Now the length of time users load laptop have also become targets regardless of the manufacturers were forced to charge current set so high, so the first step is to reduce the current load.

Lithium-ion batteries is very precious, good circuit load control is required. With this method of pricing can reduce the load current to prolong battery life while using the notebook’s original charging circuit controls the charge current to achieve them is also relatively simple, just buy a sheet of power (that is, food in a sort of book, it is better to buy two, followed by the methods referred to another use, should be of good quality), and resistance can be, and note heads resistance should be greater, after all the above, there are about 2W of power Otherwise, it would be more resistant to heat, the best use of a constant resistance over me, this resistance wire resistance and temperature independent basis. However, the shortcomings of this approach is also very clear is that, while not charging the work with the laptop lighter load current problem is solved, and now pay problems. In fact, it is difficult, after all, the laptops are used at work, the discharge current varies with the serviceability, the method mentioned here is the limited capacity of the VGP-BPS2C battery is designed specifically for the restore operation.

To start the machine, within the parameters of power management will never go into standby mode (standby) and hibernation (hibernation), others are made more energy saving modes, including including processor speed, turn off hard disks, turn off the screen, so also in TP management process of closing some unused material, such as sound cards and so on, then open the status window battery display, and allowed to run in the foreground. Close other programs, including screen saver and other regular programs running. Do not use the machine, do not close the lid, let the battery discharge is completed (not to discharge the minimum value is set to 0 can be set at 3%). Display and hard drive after closing the discharge current of approximately 0.5 A (IBM R31 can be performed on a minimum discharge current), the battery discharge to a minimum value determined after the machine s ‘automatically stops.

The discharge lasted about 4 hours, depending on the capacity of your battery may be different in different.

Finally stressed that the above method is not dead, and in particular, discharge, or 10 times what can be done once and elsewhere also

Battery does? Charge is best done with a low load current, of course, if the need to use the sony VGP-BPS2A battery directly to the power plug inserted into a laptop on it.

Purchase and use common sense of lead-acid battery for electric bikes

First, choose the right direction

1, see product logos are complete. Including the name of the manufacturer, model specifications, date of manufacture, mark, see if they are consistent within and outside the mark, in particular, to check whether there catchy product identification of the body the production date should pay attention if, in the near future.

2, note the appearance of the VGP-BPS2B battery. See if there is a distortion, cracks, scratches, and signs of leaks. Battery terminals should be clean, no rust, signs must be clear.

3, concerned about the electric car batteries rated capacity marked on. More rated capacity marked on the battery discharge time of the longer battery, it is better not to buy non-rated batteries marked, but pay attention to whether a dedicated electric vehicle, if more capacity marking should be based on design capacity shall prevail.

4, choose well-known businesses, large enterprises branded batteries. Batteries are generally provided by a manufacturer of industrial batteries, different brands, different manufacturers of batteries as other advantages and disadvantages, the price level is also divided. Well known, the size of large companies, technological solid after-sales service is good, battery quality assured.

5, corresponding to the purchase and the VGP-BPS10B battery charger with an intelligent automatic. The charger should automatically adjust the size and timing of recharge is beneficial to prolong battery life.

Secondly, the use of common sense

UPS 1, when used in Start electric car, the wind and uphill, it is the best use of manpower to help cars start from simple models of electric car launched in the wind riding up and high winds should be used when the foot help to reduce the battery charge and prolong their life, luxury models should be slow to start electric vehicles

Start step should not be diverted to turn in the late phases of hard acceleration in the descent, you can switch to electric cars to open. When the electricity shortage, they should reduce the speed of cycling, regardless of when they should not be mounted in the power of the state lacks tension.

2, using electric bike, do not overload. Electric bike’s overall design load of 75kg, which is a single person riding overload results in long VGP-BPS13A/B battery high discharge current, which damages the battery, which is the main reason for the shortened life of the battery.

3, should pay attention to the battery capacity over time and circumstances change. In general, with increasing frequency of use, the battery capacity will be gradually decreased. In the case of low temperatures, the battery capacity is reduced when temperatures can be restored later.

4, master the correct method of charging. Battery suitable temperature from 0 ~ 40 ℃, the charge should be at room temperature. Should pay attention to the charger charging status and a normal load of time to prevent the VGP-BPS9 battery due to charging or over charging, charging abnormal was considered necessary to seek professional help as soon as possible to avoid damage the battery. Cooldown after use, preferably fresh daily as a travel over 20 kilometers an office in a timely manner is preferable not exhausted, recharge isoelectric. Long-dormant, it is necessary to add from time to time on the battery.

5, regular maintenance of the battery. Battery life after a long time, if found low battery, especially when fever battery grave or her own maintenance staff should be invited to open the battery cover, remove the cap rubber alone Giga water 5 ~ 15ml, extended battery life. In addition, models, old and new batteries can not be inconsistent with the use of series or simultaneously, the various manufacturers of batteries can not be mixed. Replace the battery, it should be a group of his replacement.

6, attach importance to the pollution of the battery. Suggested that given the designated recycling of waste batteries, do not carelessly discarded in order to avoid environmental pollution.

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.
