Laptop has been her charm as the general computer enthusiasts, especially young family seeking attention. Most new notebook computers in the million or more, because of the cost of non biggest names in hard to accept; and second-hand laptop relatively cheap, and its function in general can satisfy the need, so buy used laptop computer enthusiasts not unusual.

However, after all, second-hand laptop second-hand goods, is used by others, and its uneven performance, compared with the new notebook, the biggest difference is the built-in battery should be working time, a little better able to work 2-3 hours, poor or even one hour is not that, Imagine, such a battery, just in front of friends gestures some low-power warning appeared that many did not face ah! Although second-hand laptop computers also are equipped with AC power adapter, but if only relied, and what different desktop? Buy notebook computers will be lost meaning.

In order to play their second-hand mobile notebook advantages, we must make efforts in the battery such as Acer TravelMate 240 Battery, Acer BTP-52EW Battery, Acer BTP-63D1 Battery, Acer BTP-42C1 Battery, acer BTP-44A3 Battery, Acer BTP-550P Battery, Acer BTP-73E1 Battery, Acer BATCL50L Battery, Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery. Laptop battery has been a large "books" fans feel is a very mysterious thing, that it is very high technical content, does not. The following is a laptop battery's internal structure.

In which we can easily see, by the number of single batteries in series and parallel and form a battery pack, together with the battery protection circuit, constitutes a piece of notebook batteries. Whether you use a laptop what brand, and its built-in battery's internal structure are similar. According to the type of battery to the internal points, most can be divided into nickel-cadmium batteries, nickel metal hydride batteries, lithium batteries, lithium polymer batteries. The nickel-cadmium batteries, nickel metal hydride battery has a memory effect as the capacity of small and other shortcomings are gradually being weeded out, lithium ion batteries with large capacity, small size, light weight, low self-discharge advantages, such as notebook computer has become the mainstream of the battery set.

Used notebook computers as their production was so long ago, after several years through use, its battery's working time greatly reducing Er need Genghuan, Ge Zhong brand of notebook computer batteries shape Du Ge is different, not interchangeable, the appearance of order to Goumai Dao Xiang Tong, Xiang Tong models of second-hand laptop computer batteries be prohibitively difficult. How do? Of course, this too difficult to learn DIY spirit with fans! After using various means (such as software maintenance, charging and discharging several times the depth of activation, etc.), are invalid or effect

But our own hands, not the cost it takes more than 50 yuan! Worth a try.

Have a tag line said: "The biggest operation - completely changed", I tell you today is to become the scrapped on laptop battery brand new operation, the charge is not into power, the capacity to reduce the battery replaced. "Reborn", may at first sound seems to be scary, difficult-like, actually read the contents of the back you will understand, as long as the fans a little tinkering can have success, I believe you can do a back surgeon, to their own laptop computer batteries surgery.

One or two weeks before I make a journey overseas, I make a packing list and check items off as they go in my luggage. In addition to the packing list, I also have my electronic devices list.

With all of the gadgets and gizmos, wires and cables, I need a list to make sure that I have everything. It is no fun to arrive in a foreign country and not be able to use your notebook computer or photographic equipment.

First and foremost, I check my portable computer. I want to make sure that I have everything. So, I check to make sure that I have my power supply and spare battery such as Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, Acer BATCL32 battery, Acer BATCL32L battery, Acer Aspire 2000 battery, Acer Aspire 2016 battery, Acer Aspire 2200 battery, Acer BATBL50L6 battery. I also have an USB device that converts one port into four. I prefer to use a mouse, so I pack that too. I bring a LAN cable in case there is no wireless available in the hotel.

I already have a power strip that will accept 3-prong electrical plugs. This is an absolute must as a 3-prong plug will not work in most Thailand electrical outlets.

Next thing I do is charge up my camcorder batteries. I like to take pictures of my entire holiday to include the departing airport, layover and arrival. I also ensure that I have my memory card and my spares. I also have an USB device for my memory card so that I can transfer pictures to my laptop computer. I check the memory card and delete or transfer any pictures on the card. I like to start my vacation with empty memory cards.

I have a tri-band, GSM cell phone that works in Thailand with a local SIM card. So, I make sure that the battery and back-up are both charged so that I can use my Thai cell phone as soon as I hit the ground in Bangkok.

Next, I check my portable DVD player. I make sure that I have my power cord and also my DIN jacks for the TV to DVD connection. I charge the battery and make sure that I have the small remote control and that the battery is operational.

Packing up all the charger cables and wires on the very top of my luggage makes for easy finding when I arrive.

I also have some minor electronics. I have sound reducing headphones that I pack in my carry-on. No real electronics, but I do make sure that I have 4 AAA batteries. That way I have 2 to use and 2 spares. My portable MP3 player gets charged via USB on my laptop and will last the entire 15 hours I am in the air.

Checking your electronic devices before you go, charging all of your batteries, and packing all the cables and wires, will make your vacation go electronically smooth.

Battery Technology Charging lithium-ion batteries

Battery Technology Charging lithium-ion batteries

There is only one way to charge lithium-based batteries. The so-called ‘miracle chargers’, which claim to restore and prolong batteries, do not exist for lithium chemistries. Neither does super-fast charging apply.

Manufacturers of lithium-ion cells have very strict guidelines in charge procedures and the pack should be charged as per the manufacturers “typical” charge technique.

Lithium-ion is a very clean system and does not need priming as nickel-based batteries do. The 1st charge is no different to the 5th or the 50th charge. Stickers instructing to charge the battery for 8 hours or more for the first time may be a leftover from the nickel battery days.

Most cells are charged to 4.20 volts with a tolerance of +/?0.05V/cell. Charging only to 4.10V reduced the capacity by 10% but provides a longer service life. Newer cell are capable of delivering a good cycle count with a charge to 4.20 volts per cell. Figure 1 shows the voltage and current signature as the lithium-ion cell passes through the charge stages.

Figure 1: Charge stages of a lithium-ion battery such as Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery, Acer Aspire 1410 Battery, Acer TravelMate 4500 Battery, Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery. Increasing the charge current on a lithium-ion charger does not shorten the charge time by much.

Although the voltage peak is reached quicker with higher current, the topping charge will take longer.The charge time of most chargers is about 3 hours. Smaller batteries used for cell phones can be charged at 1C; the larger 18650 cell used for laptops should be charged at 0.8C or less. The charge efficiency is 99.9% and the battery remains cool during charge. Full charge is attained after the voltage threshold has been reached and the current has dropped to 3% of the rated current or has leveled off.

Increasing the charge current does not shorten the charge time by much. Although the voltage peak is reached quicker with higher charge current, the topping charge will take longer.

Some chargers claim to fast-charge a lithium-ion battery in one hour or less. Such a charger eliminates stage 2 and goes directly to ‘ready’ once the voltage threshold is reached at the end of stage 1. The charge level at this point is about 70%. The topping charge typically takes twice as long as the initial charge.

No trickle charge is applied because lithium-ion is unable to absorb overcharge. A continuous trickle charge above 4.05V/cell would causes plating of metallic lithium that could lead to instabilities and compromise safety. Instead, a brief topping charge is provided to compensate for the small self-discharge the battery and its protective circuit consume. Depending on the battery, a topping charge may be repeated once every 20 days. Typically, the charge kicks in when the open terminal voltage drops to 4.05V/cell and turns off at a high 4.20V/cell.

What happens if a battery is inadvertently overcharged? lithium-ion is designed to operate safely within their normal operating voltage but become unstable if charged to higher voltages. When charging above 4.30V, the cell causes plating of metallic lithium on the anode; the cathode material becomes an oxidizing agent, loses stability and releases oxygen. Overcharging causes the cell to heat up. If left unattended, the cell could vent with flame.

Much attention is focused to avoid over-charging and over-discharging. Commercial lithium ion packs contain a protection circuits that limit the charge voltage to 4.30V/cell, 0.10 volts higher than the voltage threshold of the charger. Temperature sensing disconnects the charge if the cell temperature approaches 90°C (194°F), and a mechanical pressure switch on many cells permanently interrupt the current path if a safe pressure threshold is exceeded. Exceptions are made on some spinel (manganese) packs containing one or two small cells.

Extreme low voltage must also be prevented. The safety circuit is designed to cut off the current path if the battery is inadvertently discharged below 2.50V/cell. At this voltage, most circuits render the battery unserviceable and a recharge on a regular charger is not possible.

There are several safeguards to prevent excessive discharge. The equipment protects the battery by cutting off when the cell reaches 2.7 to 3.0V/cell. Battery manufacturers ship the batteries with a 40% charge to allow some self-discharge during storage. Advanced batteries contain a wake-up feature in which the protection circuit only starts to draw current after the battery has been activated with a brief charge. This allows prolonged storage.

In spite of these preventive measures, over-discharge does occur. Advanced battery analyzers (Cadex C7000 series) feature a ‘boost’ function that provides a gentle charge current to activate the safety circuit and re-energize the cells if discharged too deeply. A full charge and analysis follows.

If the cells have dwelled at 1.5V/cell and lower for a few days, however, a recharge should be avoided. Copper shunts may have formed inside the cells, leading a partial or total electrical short. The cell becomes unstable. Charging such a battery would cause excessive heat and safety could not be assured.

Battery experts agree that charging lithium-ion batteries is simpler and more straightforward than the nickel-based cousins. Besides meeting the tight voltage tolerances, the charge circuit can be designed with fewer variables to consider. Full-charge detection by applying voltage limits and observing the current saturations on full charge is simpler than analyzing many complex signatures, which nickel-metal-hydride produces. Charge currents are less critical and can vary. A low current still permits proper full charge detection. The battery simply takes longer to charge. The absence of topping and trickle charge also help in simplifying the charger. Best of all, there is no memory but aging issues are the drawback.

The charge process of a lithium-ion-polymer is similar to lithium-ion. These batteries use a gelled electrolyte to improve conductivity. In most cases, lithium-ion and lithium-ion-polymer share the same charger.

Batteries are an essential part of most modern gadgets, and their role is expected to expand as they’re incorporated into vehicles and the electric grid itself. But batteries can’t move charge as quickly as some competing devices like supercapacitors, and their performance tends to degrade significantly with time. That has sent lots of materials science types into the lab, trying to find ways to push back these limits, sometimes with notable success. Over the weekend, there was another report on a technology that enables fast battery charging. The good news is that it uses a completely different approach and technology than the previous effort, and can work with both lithium- and nickel-based batteries such as Acer LCBTP03003 Battery, Acer Aspire 1300 Battery, Acer BTP-APJ1 Battery, Acer BTP-AQJ1 Battery, Acer BTP-ARJ1 Battery, Acer BATCL32 battery, Acer BATCL32L battery, Acer Aspire 2000 battery, Acer Aspire 2016 battery, Acer Aspire 2200 battery, Acer BATBL50L6 battery.

The previous work was lithium-specific, and focused on one limit to a battery’s recharge rate: how quickly the lithium ions could move within the battery material. By providing greater access to the electrodes, the authors allowed more ions to quickly exchange charge, resulting in a battery with a prodigious charging rate. The researchers increased lithium’s transport within the battery by changing the structure of the battery’s primary material, LiFePO4.

The new work also gets fast charges, but by a rather different route. The authors, from the University of Illinois, don’t focus on the speed of the lithium ions in the battery; instead, they attempt to reduce the distance the ions have to travel before reaching an electrode. As they point out, the time involved in lithium diffusion increases with the square of the distance travelled, so cutting that down can have a very dramatic effect. To reduce this distance, they focus on creating a carefully structured cathode.

The process by which they do this is fairly simple, and lends itself to mass production. They started with a collection of spherical polystyrene pellets. By adjusting the size of these pellets (they used 1.8µm and 466nm pellets), they could adjust the spacing of the electrode features. Once the spheres were packed in place, a layer of opal (a form of silica) was formed on top of them, locking the pattern in place with a more robust material. After that, a layer of nickel was electrodeposited on the opal, which was then etched away. The porosity of the nickel layer was then increased using electropolishing.

When the process was done, the porosity—a measure of the empty space in the structure—was about 94 percent, just below the theoretical limit of 96 percent. The authors were left with a nickel wire mesh that was mostly empty space.

Into these voids went the battery material, either nickel-metal hydride (NiMH) or a lithium-treated manganese dioxide. The arrangement provides three major advantages, according to the authors: an electrolyte pore network that enables rapid ion transport, a short diffusion distance for the ions to meet the electrodes, and an electrode with high electron conductivity. All of these make for a battery that acts a lot like a supercapacitor when it comes to charge/discharge rates.

With the NiMH battery material, the electrodes could deliver 75 percent of the normal capacity of the battery in 2.7 seconds; it only took 20 seconds to recharge it to 90 percent of its capacity, and these values were stable for 100 charge/discharge cycles. The lithium material didn’t work quite as well, but was still impressive. At high rates of discharge, it could handle 75 percent of its normal capacity, and still stored a third of its regular capacity when discharged at over a thousand times the normal rate.

A full-scale lithium battery made with the electrode could be charged to 75 percent within a minute, and hit 90 percent within two minutes.

There are a few nice features of this work. As the authors noted, the electrodes are created using techniques that can scale to mass production, and the electrodes themselves could work with a variety of battery materials, such as the lithium and nickel used here. It may also be possible to merge them with the LiFePO4 used in the earlier work. A fully integrated system, with materials designed to work specifically with these electrodes, could increase their performance even further.

Of course, that ultimately pushes us up against the issue of supplying sufficient current in the short time frames needed to charge the battery this fast. It might work great for a small battery, like a cell phone, but could create challenges if we’re looking to create a fast-charge laptop.

A laptop battery pack includes a battery of cells, a casing or housing to protect and contain the cells, interconnect means for interconnecting the cells within the casing and conductors running from the interconnected cells to external terminations. The pack also includes a thermally sensitive circuit breaker which serves to disconnect the cells in the event of excessive cell temperatures. The battery pack may include a measuring-resistor strap having two projecting measuring contacts, which forms a portion of the conductors that couples the battery terminals and pack terminals.

A separate current-measuring circuit mounted in the housing provided in the battery pack is coupled to the projecting measuring contacts. A control module in the battery pack receives signals representative of cell voltage, temperature derived from a temperature sensor arranged in thermal contact with the cell and cell current derived by measuring the voltage across a sensing resistor with respect to the external negative voltage. A thermally sensitive circuit breaker provided in the battery pack is in thermal contact with the battery cells and is arranged to disconnect the cell current in case of excessive cell temperature. Usually the laptop battery consists of chemical cells and digital circuit. The success rate of the laptop battery depends on the battery type. Laptop batteries such as Acer BTP-42C1 Battery, acer BTP-44A3 Battery, Acer BTP-550P Battery, Acer BTP-73E1 Battery, Acer BATCL50L Battery, Acer TravelMate 290 Battery, Acer TravelMate 4000 Battery, Acer TravelMate 2300 Battery, Acer Aspire 1680 Battery, Acer Aspire 1410 Battery, Acer TravelMate 4500 Battery can be repaired but the work is often time consuming.

A characteristic laptop battery connection consists of positive and negative battery terminals, thermistor, clock and data. The positive and negative battery terminals are located at the outer edges of the connector. The positive and negative battery terminals have elasticity of demand to connect the battery outer shell. A thermistor wire is provided at the outside to allow for temperature protection. The most common thermistors are 10 Kilo Ohm NTC or 10kOhm at 20°C or 68°F. It is always better to use the thermistor during charge and discharge to protect the battery against overheating. The inner contacts accommodate the clock and data. Clock and data are usually combined on a one-wire system. The permanent data contained in the battery is programmed into the battery at time of manufacture. The permanent data includes battery type, battery ID number, serial number, battery manufacturer and date of manufacture. The temporary data contained in the battery is acquired during use and consists of cycle count, user pattern and maintenance requirements.

The fix terminal included in some laptop battery is made of flexible material and is adjustable for angle of demand. The fix terminal is selected from the group consisting of 30 degree, 45 degree, 60 degree, 90 degree and 180 degree. Some laptop batteries may have a solid-state switch that is normally in the OFF position. The battery will turn ON when the switch terminal is connected to the ground. Some laptop battery even includes an end-of-battery-life switch which is used to stop the functioning of the battery at a preset capacity level.

The laptop battery is mostly made of two-wire system architecture. The two-wire system is usually configured to the System Management Bus (SMBus). The SMBus is based on a two-wire system using a standardized communications protocol. The SMBus battery has five or more battery connections. The connections of SMBus battery are commonly safe but testing this type of battery appears complicated. In future, intelligent rechargeable battery packs may include some control or monitoring means to provide charge current control during recharge, charge monitoring during discharge and charge, display of battery condition, and transmission of battery condition or other parameters to external equipment.
