Improve the life time with external battery voltage display N410C

Improve the life time with external battery voltage display N410C

Has been one idea, would like to improve my ultra-thin notebook power Laptop Battery supply time, but could not find a thick or large-capacity electric batteries and confused. If we adopt the charging port for power, that is, the power adapter replaced by an external battery, then theoretically be able to achieve this functionality, but we all know N410C is a 18.5V power adapter, if the use of lithium battery-powered, then Then at least five series.

Series of sessions can be calculated for each lithium battery supply voltage is 3.7V-4.2V, 4-series before they get the 14.8V-16.8V, up to less than 18.5V nominal value, while if we adopt the words of the battery 5 That would be 18.5V-21V, voltage is too high, do not say, another five built-in lithium battery in series to give the one hand, a waste of battery-powered electric power did not say, on the other voltage is already higher than the nominal voltage of more than 10% indeed it was rather dangerous. And Li-ion battery protection circuit must be used in order to maintain the safety and long-term lithium batteries Apple PowerBook G4 Battery to use, but 5 cell Li-ion battery protection circuit is very small.

The most common laptop batteries are usually three or four series notebook needs to be the voltage, the basic 5 series does not use electricity, and therefore intends to remove from the laptop battery protection circuit to use the method can only give up the idea.

This problem has been put on hold until now, know that I found this post: There is a saying which I am most concerned about:

Disclose key specifications sticker on the back: two kinds of usage patterns optional!

One is 18.5V4.9A charge model output;

One is to never had before 15V6.0A boot mode output, just to maintain the boot and will not charge the battery Apple PowerBook G4 15inch Battery! !

(At this point the power supply how to protect the root causes of the battery has been announced, and that is by manually switching the charge to ensure that there is no running out of battery power will not again be filled before the release, so reduce the number of charge cycles, extend battery life)

The original low voltage of 15V can be used to boot laptop, and would not charge the battery, Is this not exactly what I want.

15V power supply, then the note as long as four cells in series would be sufficient to power a laptop can give and will not waste any energy in the built-in battery charging on to the laptop Apple A1012 Battery. 4 batteries just to power a notebook, but also the minimum voltage is 14.8V, is very close to 15V, it is essential that all energy can be fully utilized.

Say do your job, following the step by step to achieve my goal.

All those in need to find the whole thing: DELL's original batteries, before the rest of the old laptop, notebook already bought, and removed the batteries have been used for other purposes, but the inside of the protection circuit has not expressed any problem, but not cylinder of the kind of.

A 4.8mm standard power interface, Taobao bought 3 yuan, or be bought sony.

Battery: In order to test the time being for the first down with my N410C battery Apple M8511 Battery.

Recognize that the existence of Apple laptop battery charger failure

Recognize that the existence of Apple laptop battery charger failure

Li-ion battery Laptop Battery for iPod suspected quality problems caused by "explosive door" crisis is not resolved, but also cropped up more than laptop battery expansion events; just released to solve the problem battery performance software upgrade program, then there is the design flaw traced to notebooks. Apple continued turmoil in recent days, the flagship product ipod and laptop computer battery quality and widely questioned. This, industry sources told "Daily Economic News" interview analysis, a short time a series of similar quality problems, will likely lead consumers to a crisis of confidence on the Apple brand Apple A1185 Battery.

April 27, Apple has publicly admitted some of its MacBook and MacBookPro laptop battery charge failure may exist, and issued an upgrade program to improve battery performance. Although Apple did emphasize the laptop battery charge arising from failure, "there is no security risk, users can continue using their batteries", but according to British media reports, MacBook battery issue is much more openness Apple more serious.

It is understood that, as of now, MacBook Apple M9324 Battery users have reported more than cell expansion events, the problem is mainly due to 17-inch MacBookPro. According to one of being a system administrator user is introduced to his research lab where an order for four 17-inch, using CoreDuo processors MacBookPro, of which three units have emerged in the course of deformation of the battery swelling. He said, MacBookPro expansion precursor of the battery occurred, MacBookPro, when using the battery-powered random shutdown, but by the expansion of the battery pressure, sometimes manifested as reduced sensitivity trackpad.

MacBookPro battery due to expansion of the incident took place in foreign countries, so there are problems of a specific product model is currently unknown. The source told reporters that such a battery Apple M8403 Batterycan be replaced free of charge, but there are potential hazards such as heat explosion, and noted that this problem is the software fixes can not be solved. In response, Apple's head of public relations while China maintains that, Apple has confirmed that there is no battery failure and security risks, consumers can continue to use, and said the battery maintenance plan is not equivalent to the previous battery recall program.

The source said that in today's digital player market, Apple's share of the market share, whether Samsung, Sony, or innovation, Microsoft, can not hold a candle to. Prior to rivals also did not pose a serious challenge to Apple. But the iPod "blast door" after the incident, another series of laptop batteries Apple M7318 Battery burst expansion, design flaws and other issues, Apple's product quality will inevitably suffer some of the wavering of suspected users, and even Apple's brand loyal "fans" will also be right already have doubts about product quality. Coupled with respect is not yet on Apple's iPod "explosion" problem and notebook design flaw open to respond to, nor taken any substantive apple PowerBook G3 Battery initiatives. Apple brand that consumers trust crisis, "may be only a matter of time only"

laptop batteries were blasting the risk of explosion

Yesterday, there was the Hong Kong media reports, laptop 6280 mobile phone Laptop Battery models such as the use of original batteries and chargers charge, there will be expansion of the battery and the risk of explosion at any time. Reporter visited the store in Guangzhou found that mobile phones, laptop is the use of a variety of hot-selling models which BP-6M battery. laptop, China issued a statement yesterday evening, saying the mainland of China yet to receive similar complaints and, if consumers find that "swollen" and original laptop batteries, as long as the battery to provide the original purchase documents, the company will provide free replacement, even if the the battery has exceeded the warranty period.

"Batteries to explode at any time"

According to Hong Kong's "Ming Pao" report, the past, many mobile phone battery Compaq EVO N610C Battery explosion accidents, finger to point in the non-original batteries, but the newspaper found that very common in the laptop 6280 model mobile phone, even with original batteries and chargers charging, also appeared Swelling can not be combined to make cell phone battery problems. Experts view the issue of the battery, the extent directed swollen up to "never acceptable" level of risk, the battery to explode at any time.

Reported that the laptop spokesman said that as long as the people hold the documents to prove that sufficient expansion of the original laptop battery is power, regardless of whether the maintenance period has expired, can laptop's maintenance department to replace the battery free of charge. The newspaper found that charging undue expansion of the laptop mobile phone battery Compaq EVO N620C Battery , model BP-6M, apply to the laptop N73, N93, 3250,6233,6280,9300, and 9300i phones.

No battery swollen Mainland reflection

Xingang West Road in the Haizhu District, PARKnSHOP supermarket counters to display the various models of laptop. Salesman told reporters that his sales of laptop mobile phones more than a year did not come across to consumers reflect the original battery swollen situation. There, an original BP-6M battery needs to be 340 yuan. The salesman said that, according to his experience, the battery charging time may be made up too long inside the heat. The fourth floor of the Tianhe City, a number of mobile phone stores, laptop Compaq Presario 1200 Battery N73, N93, 6280 cell phone, and BP-6M battery also remains on the shelves. Sales staff and customers have expressed their suspense did not see the battery swollen reported.

"Original Genuine meet safety standards"

Yesterday evening, laptop China sent a statement to the newspaper, saying that all original genuine laptop (mobile phones and accessories) to meet domestic and international safety standards, you can rest assured that use. As a Hong Kong newspaper reporter refused to provide samples of the battery mentioned in the news, the company can not be a professional inspection, it is difficult to identify the battery Compaq Presario 1800 Battery "expansion" of the specific reasons.

laptop China said that at present in mainland China do not receive the same reflected the situation, if consumers have doubts about their own battery, welcome to the laptop authorized service center for testing queries. If found "bloated" and original laptop batteries Compaq Presario 700 Battery, as long as consumers can provide the original proof of purchase the battery, the company will provide free replacement, "even if the battery has gone beyond the warranty period"

Dozens of yuan, "original battery" the most explosive

Dozens of yuan, "original battery" the most explosive

Has occurred in Gansu Province, the domestic mobile phone explosion caused the first murder Laptop Battery case suspected culprits were locked for the fake "original battery", which previously took place in the country several times by cell phone explosion fake "original battery" cause. Jinliang Ri's survey found that almost all famous brand mobile phone batteries are counterfeit products. The industry veteran revealed that most fake "original battery" are renovation of the old battery recycling, the production cost of less than 2 yuan, but that price as long as the yuan more than a dozen fake probability of explosion of the battery is very high.

Internationally well-known brands are fake

In an industry veteran Huang IBM FRU 92P1121 Battery (a pseudonym), led by journalist has to Shenzhen, Guangzhou, the two mobile phone accessories market survey and found that including Nokia, Motorola, Samsung and all other markets internationally renowned best-selling brand mobile phone battery has a original fake goods from these counterfeit mobile phone batteries form a well-known brand of view, with the real thing is almost no difference between the price cheaper than the real thing a lot. The reporters found that an international famous brand mobile phones original battery normal price to 150 yuan or so, but these fake goods there original 30 yuan, 50 yuan, 70 yuan in several grades, and in some places can be purchased for as long as ten yuan. Huang said the current market, almost half of the original batteries Compaq Armada M700 Battery are fake, which the more popular brands of mobile phones, the more fake original battery.

Counterfeit batteries that costs only 2 yuan

According to report, at present the vast majority of counterfeit brand original mobile phone batteries are used scrap batteries refurbished second-hand, the production cost of less than 2 yuan.

Huang told reporters that the production of counterfeit batteries from a number of garbage recycling factories to less than 1 yuan each piece of the price of those world-renowned brands of mobile phones to buy back old batteries into the battery inside the batteries Compaq EVO N400c Battery to find ways to get out, make up an Mold Factory 0.2 yuan each as long as the price of 0.3 yuan, or bought a new shell, simple assembly, coupled with labor costs, the entire cost of less than 2 yuan. According to Huang revealed that at present, Shenzhen, Dongguan and other places there are many international brands such production of counterfeit mobile phone batteries in small factories, 3 to 5 persons, investment San Wuwan yuan, annual profit is considerable.

The cost of 2 dollars of counterfeit produced by well-known brand with original equipment batteries generally each 8-10 yuan wholesale prices to the dark cells of the total distributor, and finally to consumers the price of counterfeit mobile phone batteries Compaq EVO N410c Battery sold for 56 ten-dollar, some should be to 70 yuan.

Counterfeit battery charging explosive

For now more than occurred in the domestic mobile phone explosion, in Shenzhen, engaged in multi-year battery production and sales Liu Ge (a pseudonym) said that those currently on the market sold more than ten dollars as long as the explosion of the so-called original equipment batteries, most likely, Consumers Do not freeloaders, or listen to sales personnel talk about "playing the special" authentic original mobile phone batteries can not have such a low price.

According to Liu Ge introduced more than ten million of these counterfeit batteries were assembled with a simple resistor made of a few, batteries Compaq EVO N600C Battery is very poor, while protecting the panel has no effect in protection, once the charge could lead to an instant high-temperature, very easily lead to explosion. Liu Ge said, the current domestic cell phone batteries do not the relevant standards, it is very difficult to monitor the relevant departments.

Reduce the battery pollution! Alkaline battery charger available

Reduce the battery pollution! Alkaline battery charger available

5, a small battery can 1 square meter of soil permanent loss of use value, a button battery Laptop Battery allows 600 tons of water pollution, drinking water is equivalent to the amount of one's life. In environmental protection is increasingly becoming an issue of globalization today, the waste problem of environmental pollution caused by the battery is indeed startling and shocking. In the "Battery pollution", the alkaline batteries they are particularly prominent, and its large number of basically every household have.

Alkaline batteries are generally after the completion of the mission in the form of used batteries into the environment, the handling of these waste batteries IBM FRU 92P1167 Battery has always been difficult to keep up with its huge consumption, according to statistics of China's annual consumption of used batteries to throw away more than 200 100 million, resulting in the battery Junk 850,000 tons. However, thankfully for environmental pollution problems arising from used batteries, many institutions and enterprises in research and to find effective solutions. One of the most eye-catching was undoubtedly the "total battery charger," the R & D, this charger can not recharge alkaline batteries IBM ThinkPad Z60t Battery in the past to break the situation, an innovative study of how to recharge alkaline batteries, so that it could be used repeatedly.

A pleasant surprise is the well-known profit-based industrial battery charger manufacturers, recently revealed that, after long years of in-depth study of its effort to build the alkaline battery charger has finally successfully developed, will soon launch an "all red charger "Named the world's first hybrid alkaline nickel-metal hydride smart charger. This is said in the current within the battery industry is unique in that it gives not only the nickel-metal hydride batteries, and can give an ordinary alkaline battery charging, the battery can make the most of all to fully reuse to achieve the ease or even eliminate the battery pollution.

The industry believes that to the alkaline battery is really a good way to solve the battery pollution, if the promotion of universal access, the battery IBM ThinkPad Z61t Battery pollution issues can be a better solution. All along, due to battery consumption, the density is not large, for convenience, many families did not use rechargeable batteries in general is the purchase of new alkaline batteries, throw away old batteries. The international pass all-around red charger can allow consumers convenient and safe charging of alkaline batteries, no need to change the way people develop long-term use of alkaline batteries consumption habits. It can be expected, if each household alkaline batteries IBM 40Y6793 Battery are recharged through the use of all-round red charger, it will greatly reduce the number of used batteries, you can reduce the maximum battery pollution.

Although the used batteries to the natural environment pollution caused harm to our already well known, but the threat of environmental pollution because it is invisible, long-term, and 1:01 to difficult visual experience. Therefore, to solve the battery problem of pollution, but also need to be addressed is the environmental awareness. Only that everyone has awareness of environmental protection, and the battery IBM FRU 92P1125 Battery can be expected to solve the pollution problem, but the education of social work is not a one or a few companies able to complete and require all social forces to participate in, in order to future generations, the need of all citizens support the use of alkaline batteries will give the all-around red charger is to support environmentally friendly way.

Digital Camera Basics: About the battery inside the type

Digital Camera Basics: About the battery inside the type
Digital camera battery needs to maintain normal operation. Under normal circumstances, a digital camera can be used dry batteries Laptop Battery, alkaline zinc-manganese batteries, nickel-cadmium batteries, nickel-hydrogen batteries, lithium-ion batteries and lithium batteries as its power supply.

Alkaline zinc-manganese batteries

This battery is very easy to buy in the market, get 5 batteries, they have not been of special materials and technological innovation, the use of such batteries are mostly at the bottom of digital camera products. Because a wide range of marketing, so the user need not worry about the price of the battery, but also because of technology, common, its power supply and staying power is far inferior to other than a few batteries. Sometimes, his power is insufficient to pull the launch of digital cameras and even IBM FRU 92P1137 Battery digital cameras will be affected.

Ni-MH battery

This battery is an early alternative to nickel-cadmium batteries, as opposed to nickel-cadmium batteries, nickel-metal hydride batteries have a more compelling advantages. It greatly reduces the existing nickel-cadmium battery "memory effect", which makes the use of nickel-metal hydride batteries more convenient and more long-term cycle life (up to 1000 times). In addition, the Ni-MH battery also has the power of high capacity, large depth of discharge, overcharge and over-discharge resistance, charging time is short and so obvious advantages. The most important thing is to use nickel-metal hydride batteries are no longer toxic heavy metals as a material that can eliminate its impact on the environment. At the same time, in the electrical properties with the nickel-cadmium batteries are similar, in practical applications can replace IBM 02K6651 Battery nickel-cadmium batteries without the need for any transformation of the camera.

Of course, the Ni-MH battery is not perfect, it also exist some disadvantages. It is relatively poor high-temperature properties, in temperatures above 45 degrees Celsius environment, as well as 0 degrees Celsius below the low-temperature environment, the nickel-metal hydride batteries will not work, or even impossible to start the camera; In addition, the battery self-discharge rate is quite high , the storage period of time will find it significantly reduced the electricity; there is a nickel-hydrogen batteries also exists a slight memory effect.

Lithium batteries

Lithium-ion battery IBM 02K6928 Battery prices higher, but it has a light weight, large capacity, energy density advantage compared with the nickel-metal hydride batteries, lithium-ion batteries are relatively portable, while the energy is higher than 60%. Because of this, lithium-ion battery production and sales are increasingly more than nickel-metal hydride batteries, a digital camera is now mainly used as one of the battery. In addition, the lithium-ion battery is almost no "memory effect" as well as the advantages of non-toxic substances is also an important reason for its wide range of applications.

Lithium-ion batteries and lithium batteries state of technology, performance, relatively well, only slightly higher prices, pay attention to use relatively complex, in particular, lithium-ion battery IBM 02K6620 Battery charger must be "dedicated", it can not charge the battery with other compatible. Alkaline zinc-manganese batteries, although the price is low, consumers could afford, but its short life, long-term use of ordinary consumers can hardly bear the cost. In contrast, nickel-cadmium batteries, Ni-MH battery is more mature in manufacturing technology, the price more reasonable battery.

If you are using does not match, or not pay attention to save the battery IBM 02K7039 Battery, the battery will not shoot you when you run out of a few pictures. The following approach can save the battery usage: first, try to avoid using unnecessary zoom operation; second, to avoid the frequent use of flash, flash is a big power, we try to avoid using; third, when adjusted better to use the viewfinder when the picture composition device, rather than using the LCD. Because most digital cameras are due to open the LCD viewfinder and consume more power, turn it off can increase two to three times the battery standby time; Fourth, minimize the use of multi-shot. Most of the multi-shot digital camera built-in cache to use the fuselage to temporarily save the digital photos. If regular use of these caches, then the required power is very large. Therefore, IBM ThinkPad X60 Battery reducing the use of Continuous and dynamic image video capture function, saving of much help.
