Reply – How do you keep your battery going for as long as possible?

Tuesday, November 10th, 2009

I found the friend’s question a few minutes ago. I was busy in recent days, so i didn’t have enough time to manage my blog. “I am sorry for everyone”.
Now i wrote the article to reply the friend whose email is yummy1113@163.com. “Thank you for supporting my work”!
There are 10 ways to keep your battery going for as long as possoble:
1.Defrag regularly – The faster your hard drive does its work – less demand you are going to put on the hard drive and your battery. Make your hard drive as efficient as possible by defragging it regularly. (but not while it’s on battery of course!) Mac OSX is better built to handle fragmentation so it may not be very applicable for Apple systems.
2.Dim your screen(But it is harm to your eyes) – Most laptops come with the ability to dim your laptop screen. Some even come with ways to modify CPU and cooling performance. Cut them down to the lowest level you can tolerate to squeeze out some extra battery juice.
3.Cut down external devices – USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use. It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.

4.Keep operating temperature down – Your laptop operates more efficiently when it’s cooler. Clean out your air vents with a cloth or keyboard cleaner, or refer to some extra tips by laptop-battery-charger.net.
5.Prevent the Memory Effect – If you’re using a very old laptop, you’ll want to prevent the ‘memory effect’ – Keep the battery healthy by fully charging and then fully discharging it at least once every two to three weeks. Exceptions to the rule are Li-Ion batteries (which most laptops have) which do not suffer from the memory effect.
6.Exercise the Battery. Do not leave a charged battery dormant for long periods of time. Once charged, you should at least use the battery at least once every two to three weeks. Also, do not let a Li-On battery completely discharge. (Discharing is only for older batteries with memory effects)
7.Keep the laptop batteries contacts clean: Clean your battery’s metal contacts every couple of months with a cloth moistened with rubbing alcohol. This keeps the transfer of power from your battery more efficient.
8.Hibernate not standby – Although placing a laptop in standby mode saves some power and you can instantly resume where you left off, it doesn’t save anywhere as much power as the hibernate function does. Hibernating a PC will actually save your PC’s state as it is, and completely shut itself down.
9.Set up and optimize your power options – Go to ‘Power Options’ in your windows control panel and set it up so that power usage is optimized (Select the ‘max battery’ for maximum effect).
10.Get yourself a more efficient laptop battery – Laptops are getting more and more efficient in nature to the point where some manufacturers are talking about all day long batteries. Picking up a newer more efficient laptop battery to replace an aging one is usually a quick fix.

How to charge the laptop battery properly

Thursday, October 22nd, 2009

The article was first posted by laptop-battery-charger.net.

The new lithium-ion batteries bought in the initial use will be conducted three times a full charge and discharge, that is, fully charged battery at least once a power, then power exhausted, repeated three times before use. In order to activate the chemicals inside the battery, so that the electrochemical reaction inside the battery into the best condition, Dell inspiron 1520 battery in the future be able to freely use the charge that is useful, but to ensure that within one month, the battery must be a complete discharge, so that the depth of discharge can stimulate the activation of the battery performance, battery life plays a key role. If more than 3 months the battery is not used again before using the same should also be carried out with the new battery charge and discharge completely three times to ensure that activate the battery.
If you use nickel-metal hydride batteries, which must control the charge time, should be careful not to frequent over-charging, otherwise it will shorten the battery life. In addition, the Ni-MH battery should be fully discharged before charging, the charging should also be fully charged, and in normal use before, but also required to complete three complete charge and discharge times.
Most users accustomed to using a laptop computer each time, plug the AC power supply, very little battery power for laptops. In fact, for at least a month should be used to power batteries once or twice, the battery completely run out, draw a line on a one-time full of alternating current. Remember this one, for rechargeable batteries will run out of power again full, useful and harmless, because the notebook computer lithium-ion batteries for use there is a certain inertia effect for a long time not to use lithium-ion loss of activity would need to re-activation. When the notebook computer when the indoor use of AC is best to remove the battery so that it always in charge state. The best off charging laptop, the battery can be fully charged, do not unplug the power in the charge half-way. Charging is completed, should be 30 minutes before use. In addition, because the battery is very easy to run out of power, most notebook computers with only a battery, therefore, part of the pen so that the computer manufacturer has developed a fast charge feature that lets users run out of power after the supplement can be the fastest electric . For example, Dell notebook computer is equipped Express Charge feature, you can recharge in one hour more than 90%. Because according to charge and discharge characteristics of lithium batteries, if the current fast charge to 100%, the battery life on the big warning to shorten, so the dell inspiron 700m battery back of 10% will be replaced by slow-fast-charge before the charge to extend battery life.For the absence of such features as a standard laptop, the best way is to shut down charging, charging off shorter than the boot charging more than 30% of the charging time.How to make good use of laptop batteries battery, how to extend their use of time and the use of life and so on, is undoubtedly the troubled minds of the majority of notebook computer users to a problem.
Temporary non-use of laptop computers, in order to conserve battery power, we can set the power management program, allowing the system to enter sleep mode after a period of time, but this is a shorter or longer will have to wait a few minutes, there is no way to make laptop computer system immediately enter the sleep state?
Notebook computer system to enable quick access to dormant state of a simple method is to directly close the display. Press the display would require little effort, you can make notebook computers into sleep mode immediately and effectively conserve battery power. When you need to re-used time, as long as the opening screen, the system will automatically return to pre-operational state.
The core of a power-saving over charge / over-discharge will not cause the battery monitoring circuit that the whole is full of / discharge end of the. For example, when charging other batteries start getting close to full charge when pressed, that section of bad batteries may have reached the terminal voltage of 4.30V or higher, resulting in overcharge damage, while others are sufficient dissatisfaction. Editor’s note: For internal batteries battery damage, the “Chinese computer education” 2001 No. 2 has a very good article – “notebook computer batteries DIY” worth learning from. Interest, courage and capacity of friends can try to open the battery pack, believe that the help of multimeter, you can quickly find the damaged batteries (voltage abnormality). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product. The battery charge and discharge lithium-ion battery charging poses as a way of fast charge constant current in the voltage reaches a certain value and then to slow charging constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices.Small knowledge:In general, notebook computer battery protection circuit in the part is usually voltage block, control chip, insurance, and temperature probes. Temperature protection device is usually a one-off, the inside has a fuse (some 130 ℃ Fuse), is used to monitor the voltage regulator block work. If the charge-discharge process exceptions, immediately there will be a current through the temperature protection device, will fuse fuse, the battery’s internal circuitry at this time for dell inspiron e1705 battery the open circuit state, and can not be restored. Discharge is the discharge current as small as possible, the operation is to slow down and let the CPU, hard disk stops turn, transferred the darkest the screen (or close the switch off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent premature detection of laptop battery shortage.

Repeatedly charge and discharge deeply: the misunderstanding of laptop battery

Wednesday, October 21st, 2009

The article posted by discount-battery.org.

Some users said: “the depth with repeated charge and discharge method, you can restore the performance of the DELL laptop battery, thereby extending battery life,” I think this to be relatively one-sided.

 

Notebook computers equipped with original equipment batteries, after a period of time after use, there will inevitably be of standby time.

 

As you know, before 1995 the production of notebook computers are basically nickel-cadmium batteries to power. The battery is in use, if the charge-discharge method is not correct, the battery will have a “memory effect”, thereby reducing the battery’s actual capacity to eliminate this “memory effect” is used repeatedly in the best way to charge and discharge depth way. With the emergence of nickel-metal hydride batteries, battery capacity has significantly improved, but the “memory effect” did not completely eliminate the shortcomings Dell 1X793 battery, Dell 1691P battery.

 

In recent years, lithium-ion batteries in notebook computers has been rapidly growing popularity, due to lithium-ion batteries have basically eliminated the “memory effect” problem, it is used repeatedly to restore the battery depth of charge and discharge performance of the method no longer applies. However, lithium-ion batteries why it still appear to reduce the capacity of the problem? The root causes of that situation, is used in notebook computers and the original lithium-ion battery built-in battery management system in the making.

 

Lithium-ion battery charging process of the whole, divided into “fast charge constant-current” and “constant-voltage charging current decreasing,” two phases. The so-called “constant-current fast-charge” means a charge has just begun when the charge current is fixed and the charge voltage to follow the battery terminal voltage gradually increased until it reaches the nominal voltage charging. When the battery terminal voltage has reached the standard value, the control chip will be automatically transferred to the “Constant current charge decreasing” phase, this time charging voltage will no longer continue to rise, while the charge current is to follow the battery capacity is rising gradually decreasing and finally reached zero, and so will complete the entire battery charging process.

 

After repeated charging and discharging the battery after use, its built-in chip in the charging and discharging of data will of course change. If at this time “battery management chip” has no chance to re-read the newer, more complete data, it calculated battery capacity would of course not accurate, and to the user the impression that the battery capacity has decreased, but the reality on the battery capacity and there is no real reduction in the actual. Some brands of notebook computers comes with charging management software works, that is, the process of charging Refresh “charge-discharge control chip” in memory of the data, thus ensuring the “battery management chips,” the correctness of calculations.


If you take a close look over the use of laptop computers instructions, you will find among them the “computer in use one month later, the battery should be to make a full charge and discharge operation” instructions. Its main purpose is to use the depth of charge and discharge a way to modify the charge and discharge control chip registers inside the curve data, so that the battery charge control and the nominal capacity and the actual situation of the battery corresponds to arrive at the correct battery capacity values dell inspiron 1520 battery, dell inspiron 2200, dell inspiron 6400 battery, dell inspiron 1521 battery.
