Laptop battery maintain advice

Today I came home to get last purchase I made on the internet: a new Compaq presario cq70 battery for my lap-top. The reason is that my standard battery died, or poorly cared (which I doubt). And I could resist, until the autonomy of my laptop down to 10 minutes. Therefore I searched on the net to find some guidelines and tips and avoid the same thing happen again with my new battery. Surely some of the items you surprised, at least I did. Hope you come right this short list.

First of all note that these guidelines be followed only laptop battery type lithium-ion (Li-ion)-which bring all laptops today, as other batteries such as Nickel-Cadmium (Ni-Cd) or Nickel-Hydride (Ni-MH), should receive different treatment.

Without further ado, here are those of advice:

Avoid complete charge-discharge common: Despite what many might think, the cycles of complete charge and discharge are harmful to our Compaq presario v3000 battery (based on Li-ion). Formerly it was advised it was used in nickel-based batteries, which had a so-called memory effect that these cycles will come good, but now no longer makes sense to them frequently. There is one exception: although it is not advisable to abuse the above cycles, if it is good to fully discharge the battery and re-charge to 100% from time to time (especially if you have not use it), so that the meters Load internal fit properly.

When not in use for some time, store in a cool place (not in places that can reach high temperatures or be exposed to the sun, like a car). It would also be desirable to keep a certain load (between 40 and 60% is ideal). It is very important not to keep the Compaq presario v4000 battery fully discharged for a long period of time, as it could stop working.

It is not harmful to use your laptop connected to the mains while we have the battery inserted in it. Also so we have a small UPS equipment that will save our work possible cuts. However, just as in the previous paragraph mentioned how bad it is to keep the battery fully discharged, is strongly discouraged (very bad) to maintain the battery at 100% forever. Therefore, although it is not bad to use the laptop plugged in and the Compaq presario v6000 battery in place, the ideal is to disconnect the charger when the battery is above 90% and reconnect when about 10%. The battery will last longer if you move (ie, uploads and downloads) that if you use little.

These three tips will come in handy, I'm sure by battery blog.

FAQ About The Rechargeable Battery [Laptop, Mobile, Etc] Part Two

7. Is it harmful for a laptop battery that works always plugged in?

Yes, in fact, is not only harmful, but it is a very harmful to the HP pavilion dv5 battery due to heat and stress they are subjected.
The heat generated when connected permanently diminishes the capacity of the battery to store energy. In fact, a lithium-ion battery should never exceed 60 degrees, which is pretty close to 40 º or 50 º to a working laptop.
When you plugged your computer, you're forcing your battery to Mantana always at 100% load. The constant stress that is put is also crucial.

If for example you keep a battery at 100% at 60 °, after 3 months only retain 60% of its original capacity, and its lifetime is room? HP pavilion dv4 battery Has reduced to only 12 months.

8. I will not use my device for a few months or plan to use it in a fixed location, how should I store the battery?

A Lithium Ion battery holds better over time with a 40% charge. If we keep one with 40% charge after a year will keep 96% of HP pavilion dv9000 battery capacity, while if the store charged at 100%, only 80% retained. For this reason, most devices come with a small initial charge, the 40%.

Of course, never store a lithium battery discharged. Irecuperable could cause damage.

9. The batteries may explode

Half-truth: Of all the types mentioned Compaq presario c700 battery , the lithium ion batteries are more prone to overheat and explode, because they are made of flammable materials. For this reason these batteries incorporate various electronic protection circuits that control at all times the battery status. As a general rule, it should be stored at a temperature of about 15 º

10. Lithium ion batteries are the best

Depends on the condition of the device on to be incorporated. It is true that lithium ion Compaq presario cq40 battery are the most popular due to its light weight, high capacity (up to three times the voltage per cell than a single Ni-Cd or Ni-MH) and almost no memory effect, but life is less than that of Ni-Cd or Ni-MH, worse working conditions such as extreme cold, and tend to overheat. Thus, the choice of one or other type of battery depends on the size, weight and working environment of the electronic device in question.

TO MAXIMIZE the Lithium-Ion Battery

* Aléjalas Heat: The Li-Ion Compaq presario cq45 battery are extremely susceptible to high temperatures, so use your devices in a cool environment will extend its functionality.

* Turn off the wireless transmissions: Infrared (IrDA), Bluetooth and Wi-Fi are real vampires electricity, being equivalent to maintain a cell phone in use all the time. Off these features when not needed.

* Avoid using your Compaq presario cq50 battery CD or DVD: The only expenses not borne by the laser, but also the motor that spins the disc. Better not to mention the writers?

* Reduce the brightness of the screen: Some computers automatically do it, the less light generated, less energy demand.

* Remove Compaq presario cq60 battery memory cards or USB keys: Do not let its small size fool you, energize it requires an additional flow of electricity. This is especially true for small devices such as phones or PDAs.

* Avoid using audio applications: Even with headphones, the sound generation requires a constant expenditure of energy. Worse still if they feed external speakers.

The battery factors you should pay attention when buying a battery

By laptopsbattery - October 8th, 2010, 23:37, Category: General

Batteries are all over the place -- in our cars, our PCs, laptops, portable MP3 players and cell phones. A battery is essentially a can full of chemicals that produce electrons. Once your laptop battery dead, you should buy a new one, Most people who is not good at battery selection and need a good advice.This article deals with the selection criteria.

The following points should play a role in the battery selection:
* The volumetric energy density (Capacity). This value indicates how much electrical energy a Dell hd438 battery Wh per volume (eg liters) can deliver.
* Maximum discharge current. This value plays a role for electrical equipment that need a short period of high power demand.
* Maximum discharge volt . This value plays a role for electrical equipment that need a high voltage to run.
* The weight and shape of the battery. The battery should have a shape that fits into the screwdriver.
* The memory effect in nickel-cadmium Dell d5318 batteries or battery inertia effect for nickel-MH battery. These effects are dependent on the loading and unloading. Further more, this leads to significant reductions in capacity and voltage.

Here is a list of battery types and their associated applications:

* Li-polymer Dell vostro 1710 battery for mobile phone
* NiMH rechargeable batteries for devices with constant current
* Li-ion batteries for portable electronic devices with small size and long operating time
* Lead-acid Dell latitude d630 battery for internal combustion engines
* Ni-Cd rechargeable batteries for portable electronic devices with short periods of high power consumption
*Alkaline batteries are used for clocks and remote controls .

If you look at any battery, you'll notice that it has two terminals. One terminal is marked (+), or positive, while the other is marked (-), or negative. In an AA, C or D cell (normal flashlight batteries), the ends of the battery are the terminals. In a large car battery, there are two heavy lead posts that act as the terminals.

Can we store batteries in the fridge?

We've heard that storing batteries in the fridge makes them last longer. Many people have said that alkaline batteries stored in the fridge actually prolongs battery life. But before you start store you Alkaline Apple laptop battery, there are some things you should know. Is this true? Belowe the expert Jack Smith from http://www.battery4.us explain the reason.

Many people, especially photographers, tried to reduce the Apple Macbook Pro batteries mercury aging course when not in use by storing at cooler temperatures.

Finally, it was discovered that the fridge was a great place to do this. Then in the 80's, the U.S. government banned the sale of mercury batteries due to health concerns. Since then, alkaline batteries have replaced most mercury cells once dominant. Alkaline Compaq presario f500 battery do not get the same benefits of cold storage as do mercury cells.

Most battery manufacturers still suggest store their cells at room temperature or slightly below. Most people can get by with storing alkaline batteries in a jar in a closet. The same way to Rechargeable batteries. But be careful do not to store Compaq presario f700 battery for long periods without regular charge. Rechargeable batteries are stored for a long time without being charged have a tendency to run very quickly. The battery cell activity can be reduce in the low temperature, so store in a cool place can prolong the battery life in some ways.

Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, which slows the chemical reactions in the Compaq presario cq40 battery . Such storage can extend the life of alkaline batteries by about 5%, while the charge of rechargeable batteries can be extended from a few days up to several months. To reach their maximum voltage, batteries must be returned to room temperature; discharging an alkaline battery at 250 mAh at 0C is only half as efficient as it is at 20C. As a result, alkaline battery manufacturers like Duracell do not recommend refrigerating or freezing batteries

As far as I know, the temperature more hot , the battery cell more active. So we also heard that: someone's laptop battery explode after long time working or in hot temperature. Now If your Compaq presario cq60 battery not be used in a long period, you can store it in your fridge.
