The characteristic energy of the battery is calculated as follows: Voltage (V) x amount of electricity (Ah) = energy (Wh)

Example: 19.5 x 85.8 V = 4400mAh White

We can therefore speak of energy as a power.

Reference configurations

All batteries (SONY VAIO VGN-FZ140E Battery)are sold with the original notebook Li-ion battery, which is a type of battery, ie the (lithium) material state of ionization.

These batteries are expensive, because the battery is an expensive material. Its main advantage is the amount of energy needs, can fit in a small volume.

The main advantages

No memory effect and very low memory effect (prevents premature principle used battery to 100% due to lack of maintenance of the battery).

Excellent power / volume, due to the physical properties of lithium.

Negligible self-discharge (natural discharge if the battery is used), which allows not to worry about storage.

Lithium safe before (metallic state) through an integrated electronic circuit inside (plastic mold).

Main disadvantages

The prices due to the complexity of production and materials (batteries).

Significant deterioration during the discharge of the battery below 10% (lost 20% of capacity at a time!).

Charging current is limited by technology and the dangers of domestic battery, the charge seems slow!

Low resistance to high temperatures, recommended for use at a temperature of 20-25 ° C, but should not exceed 40 ° C under the threat of real harm. Not very high temperatures in the range of 75-80 ° C is reached under the threat of explosion (no joke).

Like all batteries SONY VAIO VGN-FZ250E Battery wear out over time and nothing can reverse this process.

CAUTION:

All types of batteries (batteries, lead acid batteries and lithium batteries ...), are very environmentally friendly and should never be thrown away. You have to be completely recycled (all hypermarkets, and the collection of waste has Bricomarché skimmer).

Never try a battery of fire or repair drunk.

Increase battery life for notebook

As mentioned previously, to replace the battery is a real investment in the order of 100 € as a rule, there are some terms to know and put in place to extend the maximum duration.

These provisions are:

First, when you buy a battery, the first thing to do (after turning in W) the date of production: in fact, as already announced a battery loses its manufacturing capacity, the date is more recent times, the battery capacity is similar to advertising on the label.

Decide for imported brands of batteries, SONY VAIO VGN-FW21E Battery in particular, do not buy the cheap batteries from China, which can be very dangerous because of the production under control very little or nothing! So beware, it can be very dangerous!

Do not exceed the discharge current specified by the battery manufacturer (for example, if given 4400mAh, so it does not "pull" is more than 4.4 A for 1 hour) for fear of damaging considerably. Of course you should not use the battery to power other devices.

Announced a very important point above: no less than 10% of the load. In general, the operating system, whatever it is, only the computer into standby mode when there are only 15% capacity SONY VAIO VGN-FZ35 Battery remaining. Is it really possible to lose 20% of capacity at once, I personally lost 10% of capacity while trying to ...

Allow the battery to run quietly without him. Rest assured, if you share the power of the battery charge: one part is to charge the battery while the other is used for running laptops, so the battery is not used for the time.

Calibration: this operation is to "redefine" full charge. Because if the battery is held up (at least 10%, but when the operating system makes the laptop in standby mode) must be fully recharged continuously. In fact, allow the batteryCompaq Presario CQ62 Battery to undergo a complete download of a full charge is maintained, he said. It is recommended that this process 1-2 times a month.

Another important point is that you must remove the battery from the computer when not in use and the PC is connected, simply because all current notebook or the same batteries with electronic circuits, using batteries to prevent the load characteristic and the handset is connected.

Instead, it is best to disconnect from a laptop computer off to avoid an unnecessary burden on micro-battery.

It seems that Sony is the battery terminal of the new notebooks from 80% in order to limit wear, so do not worry. This is normal when you can watch on a Sony laptop.

Remember not to throw the battery into the trash, but recycling, and also helps if they are not in use!
