For the right notebook batteries

Saturday, September 27th, 2008

Some of the lithium-ion batteries is equipped with notebook computers, such as the use of the wisdom of the SBS cell system technology that can accurately measuring battery life, so to use up some of the worry. Although the lithium-ion batteries have many advantages, but to extend the service life of the laptop battery, the power supply to maintain a longer period of time needed to master a number of professional charging methods.

Bought a new lithium-ion batteries used in the initial, 3 to conduct a full charge and discharge times, that is, the battery at least once a fully electric, and then released to make electricity, and repeat three times before use. In order to activate the internal battery of chemicals, so that the electrochemical reaction inside the battery into the best in the future will be able to use that to charge that is free, but within a month to ensure that the battery must be a complete discharge, so The depth of discharge can stimulate cell activation performance, battery life plays a key role. If more than 3 months battery not used again until the new battery should be the same as for 3 full charge and discharge to ensure that the activation of the battery.

The use of nickel-metal hydride batteries, it is necessary to well control the charging time should be careful not to over-charge frequently, or else they will shorten battery life. In addition, Ni-MH battery charge in the pre-discharge should be in charge when they have to fully charge, and in normal use, also called for the completion of 3 full charge and discharge.

Most users accustomed to the use of each notebook computer, plug the AC power supply, with very little compaq battery power for laptops. In fact, at least a month should be used to power batteries once or twice, the battery will be fully used up, followed on a one-time full of alternating current. Remember this one, the rechargeable battery, power will run out again full of useful and harmless, as the notebook computer lithium-ion batteries used in some of the effects of inertia for a long time not to make use of lithium-ion activity in the loss of needed Re-activated. When the notebook computer using alternating current indoors when it is best to remove the battery, so as not to make it in a regular state-of-charge. Charging the best time to switch off the laptop, so that the battery can be completely full of electricity, not to charge out half-way power. Charging finished in 30 minutes before use.

In addition, because the battery power could easily use up the majority of notebook computers and only a battery, so that some pen computer manufacturers to allow the rapid development of the charge of the function so that users can run out of electricity with the highest possible speed to add power . For example, Dell notebook computer on a ExpressCharge feature, you can charge an hour more than 90%. Why not 100%? According to the lithium battery charge and discharge characteristics, always quick to charge 100% of battery life on the big been shortened, so the back of 10% from the previous charge be changed to slow soon to extend the Presario 2500 battery  charge Life.

For this is no ordinary notebook features, the best way is to charge off, the shutdown would start charging more than 30% charge to reduce the charge time.

123 notebook battery maintenance

Friday, September 26th, 2008

Some notebook battery maintenance of the experience for everyone learn from the discussion.
       First of all, get a piece of new batteries, a lot of users is in accordance with the practice of business tips in the lithium batteries used in the previous three charging even more than 12 hours. In this debate there are many on-line, but I found that in actual use, in fact, the majority of the notebook battery is not necessary. Why? Merchant said that in order to fully activate the cell’s activity is entirely new wake-up battery. For this reason it sounds very full and credible, but we have not thought about this issue. If, notebook battery manufacturers have not yet been fully activated on the play, so the product can be said that only a semi-finished products. Can not require each user to master the skills to activate the battery, it is impossible in reality. As a result, the battery factory has been a manufacturer of a fully activated. How are users to charge the battery for 12 hours in favor of the use of it? Here the author gives a negative answer, the current notebook batteries have improved power management circuits and charging management system, when the battery reached saturation, the control circuit automatically switch to short-circuit, it is only after time in a waste of time Only. How can activate the battery of this activity? In fact, the manufacturer of the battery is activated in the absence of overload protection of the battery will discharge and recharge for a long time. Therefore, charging three times before the 12 hours is not necessary.

Once again, a lot of users in the use of batteries in the very confused as to whether or not to wait until the battery run out completely before charging. In fact, this question should be answered like this, if you can do is certainly a good thing, but the premise is your problem too. Of course, I am talking about here is not referring to the excessive discharge, excessive discharge Practice has proved that the pavilion battery is absolutely harmful, it will shorten the battery life. Therefore, when the notebook prompted a time of low power consumption will be able to charge the appropriate time. Some business has repeatedly stated that its lithium battery memory effect did not, this is very irresponsible. So when you have more battery power when it is better not to charge for the good, because the memory effect is real.

Thirdly, the need for long-term battery should be how to do, into the proposed 40-50% of the electricity, placed in the shade of the low-temperature, the following parameters will be able to note the problem.

       Of course, the best month we should come out with a battery, the battery can ensure a good state of preservation, and not let the loss of full electricity and cell damage.

Fourth, in notebook computers for use in “a month after the charge should be full-time release” if necessary. Notebook computer lithium-ion batteries used in general management with a chip and charge control chips. One-chip management in a series of registers, there is capacity, temperature, ID, state-of-charge, discharge, such as the number of values. These values are in use will gradually change. Personally, I think, in notebook computers for use in “a month after the full charge should take a” leading role of these amendments is to be improper, the value of the register, making the Armada E500 battery  charge control and battery with a nominal capacity of the line The actual situation. This is why the work could not be omitted, after all, the high-priced notebook effemination still the aristocracy.

The use of the last turn on, how to make the book more batteries for a long time. Since you bought a laptop is to use it, the battery is one of consumables, as is bound to use the time to renew and scrapped. What books to allow a longer battery life? Saving technology? Sleep? Hard to let hang? Reduce the brightness of the screen so? All these methods seem to be able to increase the so-called extension of the time. But you have never thought that such a meaningful extension of the time it? I do not run any open book process, do not open display, not to hard, I can not reach a longer period of time. This would be absurd, is used to use the notebook, rather than high-sounding setting. I therefore propose that we make good use of the notebook, rather than about how to use the notebook. Perhaps, two years after the notebook market is another world, your books have reached the ranks of the retired. As long as we pay attention to day-to-day use of batteries used to, the normal cells can be used, there is no need to be timid compaq battery.

Cell phone repair and maintenance

Wednesday, September 24th, 2008

1, sometimes cell phone charger and the laptop battery is full display itself, but the actual use of a very short time, there is no battery power, how it is going on?

There are battery memory effect, such as: the aging batteries and nickel-cadmium batteries will lead to more cases. For example, a full glass of water, it is frozen, liquid water would be gradually turned into solid ice. Although the ice is not drink the water. Memory effect is similar to “freeze the liquid water into solid water” so that power can not be used, above, due to the effects of memory or battery state, so that can be converted into electricity can not be used, although it shows that mobile phone battery power Full capacity, but only a very short period of time.

2, how to prevent the battery memory effect?

Very simple and takes only a per-use mobile phones when the battery completely finished on the use of the line. This will greatly extend the battery life.

3, when the battery memory effect can try this approach?

① battery with a newspaper to wrap a plastic bag and then put it into good Overwrapping freezer for three days (newspaper can absorb excess moisture).

Three days later, ② out at room temperature for two days decentralization.

asus battery charge after two days, after the full charge into mobile phones wrapped test (estimated to save 80% -90%).

4, the battery does not charge the causes and common-sense solution?

(1) and battery charger connection is not correct, the right to be connected;

(2) Contact the battery charger or unclean, and need to clean and dry;

(3) battery has been aging and need replacement batteries.

5, battery power faster than normal, common-sense reasons and solutions?

(1) weak cell phone signal in the negative coverage area so that the power consumption accelerated in the normal coverage area, no problem.

(2) mobile phone antenna in use did not open, so that the power consumption to accelerate the use of cell phone antennas formed out of the habit of saving can be.

(3) a new battery or a long-term non-use of battery used in the first three times before to have a normal performance standards.

(4) of the old battery, or battery memory effect of battery power will be finished within a very short time consumption, the need to replace batteries at this time.

(5) batteries used in extreme temperature, low temperature or high temperature can greatly affect A3H battery  performance, often take charge.

6, battery maintenance of a few common sense?

(1) in order to extend battery life, the charging time can not charge more than the necessary period (5-7 hours); but the first three of the new battery to be used to discharge the phone automatically shut down after the 8-12 hour rechargeable ! In order to ensure that the battery capacity was sufficient to stimulate them;

(2) only when the purchase of the original factory charger;

(3) the battery does not contact with the metal with oil or contact accessories, pay attention to moisture;

(4) batteries should not be dipped into water or thrown into the fire;

(5) Do not put batteries, such as low-temperature refrigerator, such as high temperature next to the stove;

(6) to deal with the M2 battery , use of special facilities;

(7) For the battery exchange, only recognized by the cell phone battery types;

(8) to have the memory effect of batteries, each should end the use of electricity, rechargeable, battery or memory effect will be to substantially reduce battery life.

(9) battery life is normally sufficient to calculate the number of release, and therefore, adequate electricity, run out of electricity, to extend the maximum battery life
