Inappropriate power adapter may not be fully charged battery

First post by: www.itbattery.com

Bought a new battery should be three complete charge and discharge, in order to activate the internal battery of chemicals, so that the battery into the best condition. Usually do not frequently open and close the laptop, or else they will consume a large amount of battery power. If the computer is not a short period of time, it can be in a state of sleep or hang. The use of the Windows power management features, Hp 417066-001 battery power consumption can be reduced to a minimum. Can also download a power management software used to manage power of books, recommended Le Power Center is a free service designed for notebook power management software!

First, the battery charge

In order to improve efficiency and ease of use, in the notebook battery charge is generally used when the fast charge mode, a charge time in the 1.5 to 3 hours. Ni-MH battery current approach to the general charge, and temperature control (that is, to a certain time interval check the battery's temperature rise) or law-ΔV (Ni-MH battery capacity reached 100% before the Hp F4486B battery voltage was gradually increased However, 100% charge capacity, because of its heat through the Hp F4486A battery cell voltage drop, and so have a drop-ΔV) measured as a result of control of charging on the basis of whether or not to terminate, together with the TCO of control (with temperature Based on the charge to cut off, cut off the temperature of 60 ℃), to ensure the safety rechargeable nickel-metal hydride batteries. Lithium-ion battery chemistry in its decision to charge, first with the constant current charging mode, constant current charge to 4.2V when the (single-core or a few energy-saving power when the parallel core voltage) into the charging voltage, Pressure dropped to 100mA charge current around, stop charging.

Although many notebook computer batteries using the wisdom of the battery technology can be accurately measured and the state of charge of battery life, allow users to use many of the worry, but the Hp CGR-B1870AE battery charge when we should pay attention to the following:

1. Rechargeable batteries should be for the ambient temperature 0 ℃ ~ 45 ℃ temperature scale. The process of charging the battery temperature will affect the charging efficiency and service life, so when conditions permit, the best lithium-ion batteries in 10 ℃ ~ 30 ℃ temperature range for battery charging, so as to achieve the best efficiency of the charge . Ni-MH battery temperature control is the use of the law or law-ΔV to detect whether the battery is full, the experiment showed that: charging the higher the temperature, the more it is not easy to judge whether the battery is full. Therefore, Ni-MH battery charge when the desired temperature in the 10 ℃ ~ 20 ℃ between.

2. If the laptop's AC power adapter is not a great power, rechargeable Hp Pavilion ZD7000 battery, if conditions permit so that the machine should be shut down or in standby mode without any operation. Because the notebook computer power adapter can provide a certain degree of power is, the system load large (such as the use of hard disk drive or load time, and so on) the time allocated to the battery power on the small, it decreases the charge current, the current AC power adapter from the power margin decision. If the battery is less than the current requirements of the charge current, so if things continue this way will affect the battery's working life. Some notebook computers on the statement called for the laptop battery will not operate this is the reason. We can power adapter and notebook computers rated voltage and current power adapter to calculate the margin of power, which decided to charge the battery when the need for shutdown. The method is simpler: To compare the shutdown and shut down both cases, rechargeable batteries used in time, if the difference more, this laptop's battery charge in the best when it shut down.

3. To ensure that the use of your laptop's power adapter match. Inappropriate power adapter may not be fully charged battery, or battery meter can not correctly display the battery power.

Second, the Hp PP2182D battery discharge

1. Can discharge the battery in -20 ℃ ~ 60 ℃ temperature range, preferably at -10 ℃ ~ 45 ℃, because the temperature is below -10 ℃ or 45 ℃ higher than when the battery discharge capacity Will be less than the rated capacity, leading to lower battery performance (with the exception of special applications, the vast majority of laptop users, the ambient temperature is generally not lower than -10 ℃ or higher than 45 ℃).

2. Whether or Ni-MH battery lithium-ion Hp 338794-001 battery once the battery to the laptop power supply, and so that the best discharge the battery completely before recharging, which will help extend battery life. The so-called "full discharge" the battery is not fully put the power to do, but according to different types of batteries used to power batteries to allow the value of the minimum values to the battery voltage as a basis, such as nickel cadmium, nickel metal hydride batteries single Discharge Hp PP2182L battery should not be lower than 1.0V, lithium-ion battery power-saving single-core discharge should be an end to 3.0V (should not be less than the minimum 2.7V), otherwise they will damage the battery. Because the notebook computer (or battery) has an internal control to monitor the discharge circuit (it will be based on the battery discharge condition and the work of the current machines to determine whether the battery can continue to work to maintain the machines), so in actual use, we only need to battery The power to put 1% to 5% charge to start worrying about the battery discharge would be excessive. If the practice can not fully discharge each time, then at least every other month to conduct a full battery discharge, as the notebook computer on a regular basis to the full discharge can increase the storage capacity of the battery, extending the battery life of service.

Battery Maintenance

The battery is a kind of material consumption, and its performance over time will gradually reduce. But as long as the proper use, or it could be as much as possible the extension of the life of. So in actual use, to master the maintenance of a number of laptop Hp 345027-001 battery, Hp 342661-001 battery and maintenance approach is also very positive. Actual use, we must pay attention to the following:

1. A new Hp pavilion dv6000 battery(Hp dv6000 battery) put into use, there should be 3 to 5 times the full charge and discharge, in order to activate the battery chemicals, so that the battery 's rated capacity to meet the design for the future lay a solid foundation for normal service. After long-term storage battery re-use, should also be carried out several full charge and discharge, in order to restore the original capacity. Specifically: in the BIOS, turn off the power saving options, then enter the "Control Panel" in the "power management" and "the use of power" in "battery" at the bottom of the 3 options are set to "never . "


And then select the "alert" category, for "lack of battery alarm" and "a serious shortage of battery alarm" two options before the "√" removed, and then close the screen saver, and then to the battery-powered laptops, Prompted battery to 3% to 5%, the screen brightness to a minimum (or close the screen), power up to 0%, and then connected to AC power adapter for charging the Hp HSTNN-DB20 battery, has been sufficient to 100%.


2. Machines do not use without a battery charge state, the machine should be pulled out of the power plug.

3. Do not put batteries to direct sunlight, the battery should not be stored in high-temperature environments, such as the summer's car, and so on, otherwise it would lead to reduced battery performance. According to the nickel-metal hydride batteries and lithium-ion Hp Pavilion dv8000 battery(Hp dv8000 battery) should be kept at low temperature storage properties, they kept in a temperature of -20 ℃ ~ +20 ℃ environment is the best, easiest way is to compare the battery on the refrigerator cold Interior, so as to effectively prevent the deterioration of the characteristics of the battery.

4. When we remove the laptop battery intended to be stored for a long time, Ni-MH battery to full power; lithium-ion battery and storage, according to official data, should ensure that the battery is full of state and a half (that is, about 50% in electricity ), In order to reduce the wear and tear of the battery. If a long period full of power, or fully discharged, the battery will have a negative impact on life expectancy.

5. In order to give notebook computer batteries to extend the duration of power supply, we should also conduct a number of energy-saving settings. The energy-saving notebook computer set up. Have been able to reduce power consumption, mainly because of a computer into the state of energy-saving, closed in a timely manner, that do not require the use of the equipment.

The energy-saving BIOS settings Hp 395789-001 battery: in the BIOS settings, enter the "Power" option in "Power Mode for Battery" select "Maximum Battery Life" (the largest Hp 396008-001 battery mode, that is, energy-saving mode). In addition, some do not have to manually shut down the equipment in order to save energy, such as the closure of the serial, parallel, infrared, and so on. Some BIOS settings can also idle machine shut down automatically after a certain period of time displays, hard disk or standby mode, which can be based on actual need for a corresponding set of (different types of BIOS settings may vary).

Windows in the energy-saving settings: general users, in the Windows system for the management of energy-saving operation may have a better understanding of some simple. "Control Panel", select the "power management" option, "Power Management properties" dialog box, should "use of power" set to "Portable / Laptop" reasonable arrangement "Hp Pavilion dv9000 battery(Hp dv9000 battery)" at the bottom "Turn off monitors" and "shut down hard" and "System standby" option 3.


If the battery has been significantly shortened the Hp EV087AA battery, then try to use 3 to 5 times the full charge and discharge the battery to restore some capacity. If you are using a Ni-MH battery, you can try IBM's software-specific discharge isbr01ww.exe (This is IBM's software for use nickel-metal hydride battery of the ThinkPad 390 series notebook computers designed by the trial found that a certain general ), This software can be downloaded http://epocn.chouge.com/nbsoft/sbr01ww.exe or ftp://ftp.pc.ibm.com/pub/pccbbs/mobiles/isbr01ww.exe. It should be noted that these methods not only because of frequent discharge as a result of the decline in battery capacity and effective, the service life of the battery-effectiveness of the latter is highly unlikely. Of course, still some way to save, and that is invited to the master cells for batteries.
