Laptop battery calibration techniques05.26.14

Shorter battery life, not the battery itself.

For the battery using time within 1 year, shorter battery life, often not because of battery normal aging, but because the battery in the process of many times of charging and discharging, notebook BIOS system has a miscalculation on battery power. Original battery has a certain power, but mistakenly think that the BIOS battery has run out, let your laptop to force to turn it off. If appear this kind of battery life shrink, the first battery quality problem is not busy to conclusions, and can be done by “cell calibration” this simple and easy way to let the rest of the power out into full play.

How to make “battery calibration”

Battery calibration method is more than one, there are generally three kinds of ways: using BIOS battery calibration program, manual Battery Calibration and use third party Battery Calibration software. Here mainly to talk about the first two correction methods.

Tips: do not recommend the use of third party Battery Calibration software. As for the reason, first of all need to install third party software, not the former two methods is simple; secondly, the correction principle behind is similar, there wasn’t too much unique local third party software, but also a potential security risk. So in the front two methods can complete battery calibration case, does not recommend the use of third party software.

The standard correction: correction function used the books of BIOS battery

Many brands of laptops in the BIOS, integrated with battery Calibration procedures, general English is called “‘ Calibration”, namely “Battery check”. Directly into the laptop BIOS battery calibration operation, will be finished here in asus notebook, for example, simple talk about how to operate, the operation of the other laptop similar way.

Step 1: boot, boot screen after press “F2″ to enter the BIOS menu; Through the or so direction key, the Power menu choice.

Step 2: enter the Power menu, you can see “Start ‘Calibration” option, select it and press the return key.

Step 3: then the screen will become blue, have English tips, and requested the notebook power adapter plug in to recharge the battery. After the battery is full, such as screen and prompt the user to disconnect the ac adapter. Notebook to continue after discharge the battery until the battery runs out.

Step 4: the process over a period of time, such as automatic shutdown after its battery runs out, then plug in the ac adapter to recharge the battery, but don’t start up. (charge indicator extinguished) after fully charged, such as cell calibration process is completed.

This operation is the official battery correction method, the entire process takes about 4 to 5 hours and more time-consuming. If you find that your laptop battery doesn’t work long time, such as a few months, battery life is better than at the beginning, and laptop BIOS with this function, suggested to implement it.

Introduce the necessary procedures manual Battery Calibration

Step 1: in the operating system (Windows XP), into the “power options”. “Choose to use the scheme of” power to “open”, and to “close the monitor”, “off the hard disk” is the most short time, while the system standby should be set to “never”.

Step 2: in the “Power Options” “alert”, cancel all alert options, the purpose is to let the battery is fully drained until the shutdown.

Step 3: set of finished, close the application, all closed WIFI, unplug the power adapter, battery powered. Don’t do any operation, until the battery is depleted shutdown. The estimation process is relatively long, may take several hours. After discharge, even the power adapter, the battery is full, then completed a battery calibration.

After correction, whether to try the battery life time increased, if not clear, can be in accordance with the above method again, but is not recommended for regular. If the battery has a long time of use, and the battery after correction, the effect is not obvious, it may be the battery life of its own natural aging. In addition, if the laptop battery is normal, we do not recommend battery calibration operation.

Laptop Battery Power Ratings and Power Consumption04.16.11

Every laptop battery is given a power rating in order to show you, the consumer, about how long your battery should last before it needs to be recharged. These electrical specifications are given using volts (V) and milliAmps (mAh). For example, you may see your battery is given a rating of: 10.8V, 4000mAh.

Volts and milliAmp hours are used because they measure the amount of energy used by a laptop battery. A volt (V) is a measurement used for the amount of pressure the positive and negative electrodes produce in a battery during the process of discharging energy. Amps (A) measure the amount of resistance the energy in your battery produces in order to power a laptop.

Think of volts and amps in terms of a shower. When a shower is turned on half way, the water that goes through the pipe produces a certain amount of pressure. When you turn it on to its full amount, the water produces more pressure in the pipe. This pressure, or power, is similar to the volts a battery uses. If a laptop is running simple programs, little power is needed to discharge energy into a laptop. However, if a laptop is running a DVD movie or other high energy consumption applications, more power will be needed to discharge the necessary amount of energy to run the DVD movie.

You may also notice that increasing the size of the pipe and shower head without having to open the faucet all the way will produce similar results. This is an example of the amount of resistance in the flow of energy. Measuring this resistance is measured in terms of amps. In terms of a battery, the amount of resistance is dependant on the size of the battery and the amount of energy inside.

Battery life: A Few Things to Consider

Laptop ratings are given in terms of amp hours (Ah). Amp hours measure the length of time a battery will discharge energy before it needs charging. In order to adequately measure battery life, manufacturers use milliAmp hours (mAh). This means that every 1000mAh is equal to 1Ah. What does this mean for your new battery? If your original battery is measured at 2500mAh and your replacement battery is measured at 5000mAh, then your battery run time will double.

Keep in mind that technology constantly changes. Your old battery may be rated at a lower run time than a newer one because of technological advancements that have produced longer lasting batteries.

Additionally, your battery’s run time depends on the programs you use. Some programs require more energy to run than others. Examples are: the screen (particularly if set at the brigh test setting), hard drives, CD and DVD drives, and wireless network cards. Unfortunately, there is no definite answer to the question, how long exactly will my laptop battery last? The key factor is how and what you use your laptop for.

One way of conserving power is to go to your Power Management settings icon in the Control Panel. You can shut off settings or programs you do not use. Also consider dimming your screen and shutting off your wireless card when you don’t need it.

How to rebuild a Li-Ion battery pack04.11.11

Did you recently notice poor performance of your notebook Li-Ion battery?. Don’t be taken aback, this is happening even to the best battery! Now days Li-Ion batteries are widely used in portable devices due to there excellent energy to weight ratio and for the reason they are not suffering from “memory effect”.

   These two reasons make them the best choice on portable devices, but not suffering from “memory effect” doesn’t mean it will last for ever! Chemical conversions inside the battery make it to produce electric energy but these chemical reactions aim to attenuate as time and charge cycles pass over.

   When the battery life drops significantly it’s time to search for a replacement, but you will recently find out that most of notebook batteries cost almost 1/3 to 1/2 the price of the laptop at the time you will need to replace the battery. So if you want to keep your laptop but don’t want to spend much money for battery replacement it’s time to think about rebuild it your own, replacing each individual cell inside the pack.

But before step on this you must consider many parameters messing around Li-Ion batteries, about the way they are charged and the way you must handle them.

Features of lithium Ion batteries:

High energy density that reaches 400 Wh/L (volumetric energy density) or 160Wh/Kg (mass energy density).
 High voltage. Nominal voltage of 3,6V or even 3,7V on newer Li-Ion batteries.
 No memory effect. Can be charged any time, but they are not as durable as NiMH and NiCd batteries.
 High charge currents (0,5-1A) that lead to small charging times (around 2-4 hours).
 Flat discharge voltage allowing the device to stable power throughout the discharge period.
 Typical charging Voltage 4,2 ± 0,05V.
 Charging method: constant current – constant voltage (CV-CC).
 Typical operation voltage 2,8V to 4,2V
 Recommended temperature range 0-40

Charging Characteristics:

Charging method is constant current – constant voltage (CV-CC). This means charging with constant current until the 4.2V are reached by the cell (or 4,2V x the number of cells connected in series) and continuing with constant voltage until the current drops to zero. The charge time depends on the charge level of the battery and varies from 2-4 hours for full charge. Also Li-Ion cannot fast charge as this will increase their temperature above limits. Charging time increases at lower temperatures.

Charge current is recommended to be set at 0,7CmA (where C is battery capacity). If voltage is below 2,9V per cell it’s recommended to charge at 0,1CmA. Charging environment must have a temperature between 0-40. Maximum discharge current must not exceeds 1.0CmA and discharge voltage must not go below 3,0V

 Capacity:

At a typical 100% charge level at 25, Li-ion batteries irreversibly lose approximately 20% capacity per year from the time they are manufactured, even when unused. (6% at 0, 20% at 25, 35% at 40). When stored at 40% charge level, these figures are reduced to 2%, 4%, 15% at 0, 25 and 40 respectively. Every deep discharge cycle decreases their capacity also.

100 cycles leave the battery with about 75% to 85% of the original capacity. When used in notebook computers or cellular phones, this rate of deterioration means that after three to five years the battery will have capacities too low to be still usable.

 Self discharge:

One great advantage of Li-Ion batteries is their low self-discharge rate of only approximately 5% per month, compared with over 30% per month and 20% per month in nickel metal hydride batteries and nickel cadmium batteries respectively.

Skills for extend laptop battery life04.09.11

In recent years, lithium-ion batteries in laptop computers spread rapidly, due to lithium-ion batteries have basically eliminated the “memory effect” problem, Battery it is used repeatedly to restore the depth of battery charge and discharge performance of the methods no longer apply. But lithium-ion battery capacity reduction occurs, or why the problem? The root causes of that situation, it is used in notebook computers and Li-ion battery built-in battery management system caused.

Battery management: current notebook computers, almost all adopted the “battery management” and “charge and discharge control” of two chip-level management system. The “battery management chip” placed in the notebook itself, the chip registers in the computer stores the lithium-ion battery capacity, battery temperature, ID serial number, charge and discharge status, total charge and discharge times and other important information. The data information in the course of the need to constantly refresh the actual situation. The battery built-in “charge and discharge control chip,” the most important role is to monitor and control the battery charge and discharge the entire process and be documented.

Charge: Lithium-ion battery charging process of the whole, divided into “fast charge constant current” and “reduced charge constant current” two phases. The so-called “constant current fast charge” means the charge in the beginning, Battery the charge current constant while the charge voltage to follow the battery voltage increased gradually until it reaches the nominal voltage of the charging. When the battery voltage has reached the standard value, the control chip will automatically turn into “reduced charge constant current” phase, this time charging voltage will no longer continue to rise, while the charge current to follow the battery capacity is increasing gradually decreasing and eventually reach zero, so it completed the full battery charging.

At the same time, the charge generated during the charging voltage, current and time data curve, will be recorded in the battery’s “charge and discharge control chip” in the memory. “Battery Management”Battery is through the retrieval of the data, calculated by sampling data such as battery capacity, which is what we read in the BatteryInformation in the Wh value.
