Laptop battery frequently encountered problems

Q: How to preserve the battery if I don’t use for a long-term?

 

A: Charge or discharge to about 50%, and then placed in dry, temperature of 15 to 25 degrees Celsius to preservation, either the temperature is too high and too low are easy to accelerate cell aging.

 

Q: Is that ok if Laptop battery is not removed when using the power supply?

 

A: It does not matter, the laptop battery has a protection circuit, it will not continue to charge when full.

 

Q: My battery is now run only a very short time, how should I do?

 

A: If you’ve been in the frequent use of the battery, then it belongs to cell aging, which can not be avoided, you can only consider to change a new IBM ThinkPad R32 battery or replace batteries; If you did not use battery a long-term, may also lead to this phenomenon, this time need to completely discharge (until fail to boot up) and then full recharge, repeated several times to activate the battery.

 

Q: Could I use other laptop’s power adapter?

 

A: No, there are three obstacles, the first is the notebook computer manufacturers use various different voltage, such as IBM are 16V, COMPAQ mostly 18.5V, SONY part of the model is 19.5V, they are inconsistent. The second is different laptops need different current, from 2A to 5.4A, a small machine needs small current. The third is the various manufacturers notebook power adapter interfaces are different, it is difficult to general use. Therefore, at present there hasn’t a common power adapter to all notebooks. 

 

Q: How to charge the new machine? How do I maintain the battery?

 

A: Lithium Dell Inspiron E1705 battery need to maintain a certain electromotive force to maintain its internal chemical activity. Therefore, you need to achieve full charge and discharge, in general, the first three times can be a period of about six hours of charge time, charge electric to 100% if there is no time. To avoid point charge, charge timely when less than 10%, and not to be exhausted, that would be bad to the battery; also try not to charge when higher than 60%. Battery don’t use for a long time should applied to about 50% of electricity and preserve at room temperature and dry environment.

 

Q: For the first use of the battery, should I charge 12 hours the former three times?

 

A: This is completely unnecessary, because the current notebook computers have improved power management circuitry and charging management system, when the hp Pavilion dv6000 battery reached saturation, the control circuit will automatically switch to the circuit state, so even if charge a long time is also to no avail.

 

Q: In order to prevent memory effect, we should run out before charge?

 

A: Discharge the battery is not only unnecessary before every charge, but also harmful. Practice has proved that the depth discharge of the battery will shorten the life, it is recommended to charge the battery when about 10%. When the sony VGP-BPS2A battery power is still more than 30%, you’d better not to charge, because the memory effect more or less does indeed exist.

How to identify the quality of laptop battery

Laptop battery currently on the market varies greatly, a large number of low-quality products into the market, including many counterfeit original battery, these bring great risks to consumers. For non-professional consumers, we propose several ways to select a new battery according to the following Laptop battery:

   

1. Check the package

 

a.There should be a brand. Neutral non-branded packaging products easily lead to buy inferior products or second-hand refurbished products.

b.There should be a sealed anti-static bag, anti-static sponge, etc, these are the basic configuration to protect laptop Dell U4873 battery.

c.Should have a bar code. Barcode is authority of identity unified management standard recognized by the country.

 

2. Check the appearance

 

a.There should be no scratches or obsolete sense, or it may be second-hand refurbished goods.

b.There should be clear parameters, performance, application of model identification.

c.There should be no opened spoor on hp PB992A battery cover seams.

 

3. Check there is a formal guarantee notes and after-sales commitment

 

Qualified cylindrical batteries used for formal professional notebook battery products, from the date of the factory, will be guaranteed one-year warranty. If there has no such commitment, then its use of batteries and other materials are likely unqualified batteries, the secondary batteries. Currently on the market appeared with the proliferation of laptop batteries converted by waste batteries of Japan, Korea, and inferior VGP-BPS2C batteries, this seemingly cheap products are actually a profiteering products and devastating to the normal use of the notebook computer, and may also a serious explosion causing bodily harm to consumers.

Lithium-ion batteries(b)

Lithium-ion battery security features

Lithium-ion dell laptop battery has been very widely used in people’s daily lives, so it should definitely be the safety performance of lithium-ion batteries are the first assessment indicators. For lithium-ion battery safety performance assessment indicators, the international community provides for very strict standards, a qualified Li-ion batteries in the safety performance should meet the following conditions.

(1) Short Circuit: No fire, not explosion

(2) Overcharge: No fire, not explosion

(3) hot box test: no fire, not explosion (150 ℃ thermostat 10min)

(4) needle puncture: No explosion (Ф3mm nail penetration with batteries)

(5) the impact of flat-panel: no fire, not explosion (10kg weights since 1M height batteries)

(6) burning: No explosion (gas flame barbecue batteries)

Lithium-ion latitude d510 battery safety features are how to achieve the?

Lithium-ion batteries in order to ensure safe and reliable use, the experts had a very strict and careful design of the battery safety in order to achieve security assessment battery indicator.

(1) divide 135 ℃ Automatic shutdown protection

Adopting international advanced Celgard2300PE-PP-PE three-tier composite membrane. The battery temperature reached 120 ℃, the composite membrane on both sides of the PE film hole closed, the battery internal resistance increases, the battery internal temperature down, the battery temperature reached 135 ℃, when, PP film hole closed, the battery internal circuit, the battery is no longer warming, to ensure safe and reliable latitude d520 battery.

(2) add to the electric fluid additives

Overcharge the battery, the battery voltage higher than 4.2V under the conditions of electric and electro-hydraulic fluid additives in other polymeric material, the battery internal resistance of mates increased, the formation of large area internal battery circuit, the battery is no longer warming.

(3) the battery cover composite structure

The battery cover the use of explosion-proof structure notch, battery temperature, the battery internal activation generated by the process part of the gas expansion, the battery internal pressure increased, the pressure reaches a certain degree of notch rupture deflated.

(4) a variety of environmental abuse trial

For the misuse of tests, such as external short circuit, overcharge, acupuncture, flat shock, burning and so on, examining the safety performance of the battery. At the same time, the battery temperature shock test and vibration, drops, shocks and other mechanical properties test, inspect the battery in the actual use of environmental performance under the circumstances.

Lithium-ion latitude d600 battery are a new type of green environmental protection battery

“Care for the environment, the protection of the Earth” is our bounden duty of every individual. How the U.S. environmental philosophy reflected in the action then?

As a battery consumers should buy, the use of new green battery; as the battery manufacturers should be the production of new green battery. Only through the concerted efforts of everyone to create, protect our natural beauty and harmony.

New type of battery is the green environmental protection in recent years have been put into use or are being developed for a class of high-performance, non-polluting batteries. Has been substantial use of lithium-ion batteries, nickel metal hydride batteries and are promoting the use of mercury-free alkaline manganese dioxide batteries are being developed, as well as lithium or lithium ion plastic batteries, fuel cells, electrochemical energy storage supercapacitor are new green areas of the dell 312-0068. In addition, the current has been widely applied to the use of solar photovoltaic conversion of solar cells (also known as photovoltaic power generation), also fall into this category.
