How to change laptop batteries

Laptop battery charge and discharge times just a few hundred times, so use for some time, battery life will continue to shorten, and some can only use 10 minutes. In particular, as some second-class notebook computer, battery is simply garbage, do not practical. If you encounter such a situation, how would we do? Buy a new battery of course good, but it takes a lot of money. There is no economic way? That is a notebook "heart" to have surgery for ibm thinkpad t42 battery replacement batteries.
Common tools required
Iron, digital multimeter, hot melt, electric knives, razor blades and small screwdrivers and other common tools, the other lithium batteries needed replacement to be ready to buy new batteries Note the shape, size to be consistent with the original batteries, otherwise could not put into the battery box (laptop battery models introduced see 22). As much as possible to prepare more ibm thinkpad t43 battery (laptop batteries according to the internal batteries apart and the number may be). The market can go to the local computer shops or buy electronic production, if the local market can not find the batteries can also be a way to get through mail order. A lot of this information online. The price of batteries under the circumstances, the new lithium batteries in about 30-50 yuan.
Open the battery cover
Laptop batteries have different bonding techniques. Some old-fashioned is the use of screw clamp on the battery, and some better batteries is to use ultrasonic welding, and generally use bonding glue the upper and lower cover, this time can be closer look and see what the battery slot on the block, consider the about the work that pry open the gap with a blade and a screwdriver. Available when dismantling electric knife or blade up and down along the battery cover slits cut into the junction, and a week around the slit, and then use a straight screwdriver to pry open the fujitsu fmv e8210 battery box ** slit on one side, note that excessive force can not, or it may will damage the battery or the internal circuit boards.
Dismantling available when the battery electric knife or blade along the upper and lower lid with slits cut at the
After opening the battery casing blocks, we can see the internal structure of laptop battery has. We can see that this battery is the use of six Panasonic cgr 18650hm lithium batteries, two and three strings formed by the voltage of 10.8 volts, the fujitsu fmv biblo loox t55g battery capacity 32000mah. Below we lithium batteries is to remove from the battery box down, you can use pliers to carefully slice batteries and circuit board solder joints cut off. Cut off the welding of films on the batteries be careful not to cut too much, the board should stay a little longer, as shown in the red circle marked on the Department, to facilitate new batteries and circuit board welding. Also in the demolition of the old batteries be sure to note the time, not to the battery protection circuit broke, but this is very important.
Replace with new batteries
Ready for the new batteries, if conditions allow, it is best to buy bigger capacity, this could make the battery work longer hours, but to ensure that the same model.
Battery pack before you get to know the welding connection method, in this case is the first two lithium batteries in parallel, which can double the battery capacity, then a good three batteries in parallel and then in series, allowing the fujitsu fmv biblo loox t60d battery pack voltage required to reach 10.8 volts laptop. However, the batteries in the welding time to pay attention, because the batteries are generally used for welding spot welding machine welding professional, you can see the old batteries, there will be two small spot, but a spot welder The price can be bought several new notebook battery. For ordinary diy, the common electric iron welding tool only, but the batteries chrome plated housing, it is hard on the tin, we can first use the blade to scratch the bipolar batteries, batteries Do not pay attention cover of chaos is broken. Scratched at the iron and then a layer of rosin on, and then stained with iron solder welding of batteries much easier. But note that the soldering iron and the batteries when the "intimate" time not too long, because we know the batteries overheating can cause performance degradation or damage.
If you find it troublesome, can go to the place where you buy the battery, generally these places will provide welding services. Between the batteries and the batteries can be used to connect multi-strand copper wire, is difficult because the original sheet metal welding. Some combination of batteries according to the original way to connect, and to ensure reliable soldering, solder joint should also be noted not too large, otherwise the solder will not put a good battery into the battery box! After connecting the toshiba portege m100 battery pack, battery pack with a multimeter to confirm the reliability of the connection, and then carefully soldered to the charging protection circuit.
Battery cover bonding
Before bonding the battery pack should be asked to confirm the reliability of the connection, and then determine the correct case for the work of adhesion. Adhesive fixed first battery case, the simple point can stick with hot air gun to melt the hot melt adhesive (hot air gun if no effect of electric soldering iron is also good), then place a few drops of drops, until solidified to it. Adhesion battery cover can be painted in a number of strong glue on shell (such as ab glue, etc.), and then solidified so you can use Nianshang Qu.
To activate the battery
Lithium batteries due to the purchase of storage time may be longer before use to fully carry out "active" treatment, you can boot off all power management state, so that laptop slowly discharge until it is no electricity, and then fully charged, so Repeat two to three times the battery fully charge and discharge can be restored to maximum capacity, then you can put to normal use.
Through this transformation, not only help you save large sums of money, to know the new original laptop battery will happen seven or eight hundred dollars, so calculate the transformation takes only a few batteries of the money (how much depending on your spent batteries calculation), the other for some old-fashioned laptop batteries is to buy can not find a place to buy. And modified the battery will provide plenty of power for your laptop, just bought a new toshiba satellite pro l20 battery better than the absolute poor. Heard of the "six-year-old man, three-year-old heart!" This phrase? Now your laptop is such a condition!
