Principles of replacement batteries for laptop battery

1, laptop batteries Category:

 

The media can be distributed according to nickel-cadmium Sony VGP-BPS9A Sony VGP-BPS9A/B batteries Ni-Cd, Ni-MH Ni-MH, lithium-ion battery LI, Li-Ion Li-Ion and latest polymer lithium-ion battery and now frequently used is the notebook lithium-ion batteries.

 

2, the structure and capacity laptop battery calculated as follows:

 

No matter what type of notebook batteries by battery + charging circuit protection, charging circuit is again protecting the controller chip to prevent overcharging and overheating of the battery to prevent overheating protector formed . Laptop batteries generally are 10.8V, 11.1V or 14.4V ’s. How to distinguish between the quantity of batteries inside?

Keep in mind that each voltage lithium-ion battery 3.6 V to 3.7 V, so more than three types of voltage, you must first set of three or four batteries, and the N Group composition of such batteries in packs series battery.

For example, your battery 10.8v/3600ma nominal, it may be 6-cell or 9-pin, single power-saving heart capacity 1800MA or 1200MA

Why laptop battery circuit protection should be incorporated into the pricing? This is because the lithium-ion batteries have a certain limit charging voltage, general 3.6v rechargeable battery should not exceed 4.2 V, otherwise it could explode. This requires a device for monitoring voltage of external load, approaching the stop line when the perception itself, the batteries discharge limits, General 3.6v battery can not discharge more than 2.75 V this would also lead to battery failure, and that is what we often say “over-discharge.”

 

4 Lithium-Ion Battery Model:

 

Lithium-ion battery signal is provided in accordance with its exterior dimensions, typically used in laptop batteries are the following models: 18650,18500,17670,17650,103448,103450, to 18650, for example, batteries of 18mm diameter, 65mm length therefore become 18,650.103448 and 103,450 belong to the battery box, IBM 240 series on the use of this type of battery, scale height, respectively, 10mm, 34mm, 48mm. In general, portable batteries are used batteries 18,650 or 17,670, mainly because the two larger capacity batteries are smaller and can cause the battery as needed.

5, which is battery change?

 

Change the batteries in the battery pack was originally in the batteries, replace the other batteries. Change the battery manufacturers of the battery are strictly prohibited acts, because it has a very high risk. Change the batteries when the battery itself with a soldering iron or other power tool to easily generate electrostatic discharge lead to short-circuit, causing the explosion of fire. On the other hand, due to the charging protection circuit has been written in the information original batteries (capacity, discharge curve, etc.), changing batteries is likely to cause a circuit failure protection, which can not be accused or even lead to an explosion overhead. Thus, for batteries is dangerous, and there is a risk, it should pay attention!

 

6, change the batteries need to pay attention?

 

Changing batteries is dangerous, but to save money, we must take the risk. Change the batteries before the battery needs to shine some attention (usually around 5% can be placed). Because the batteries with only a little more than their own power, if you put a fully charged battery Naqu for battery charging protection circuit will always remember your battery is fully charged, not even of electricity for the batteries, circuit is not allowed to recharge, and many of the soul after changing the battery is not charging for that reason.

In addition, changing batteries, carefully check the batteries before the model, capacity, brand, brands may differ from batteries in the charging circuit, the circuit will lock automatically (small Japanese technology development) resulting in failure of the base. So it will replace the same types of brands of batteries.

 

Also, change the batteries must be completely replaced, is not just for some batteries, it is very dangerous, they must earn perks facing a significant loss.

 

In addition, not the blind pursuit of high-capacity batteries, because some circuitry to detect the new capacity is more than the original batteries when batteries are locked, or only allowed to charge to the original capacity, therefore the success of high-capacity batteries, rate is very low.

 

7 Change the batteries need to pay attention then?

 

After changing the batteries need to pay attention to the first three charge-discharge must be at least of total liberation, which is filled with charge after a period of time, then began to use, discharge should be placed below 5% then start charging. Because the batteries and between the original circuit will be some adjustments to get an accurate measurement of power level. Some of the new-cons-battery cells in use at 30% time off immediately to 0, which is very common, indicating that the circuit is not yet complete self-calibration (calibration), the measures are not accurate. Usually after two or three times to achieve the best possible condition). Dell Inspiron 1100 battery Dell Inspiron 1150 battery

 

8, in another battery battery can draw basic?

 

Looking for another time the batteries from the battery in general could once again change the basis, as the circuit is not a problem. However, after changing several times on the basis of the welding circuit to high intensity, is not easy once again on the box, and may have missed welding, cold welding common case, so in general, do not change not the heart of another.

 

9, change the batteries will bring things:

 

Some laptops are made, and the other wearing a monitor battery or brand of battery type of software, changing the amount of testing immediate depletion of the full charge and charge-discharge curves. General Business will give you the guarantee of the time, as long as the tax by about 15% of the task of testing the line and get him back to the devil and then tested. 367759-001 F2024A
