Change chips for your laptop battery
Notebook battery is a kind of consumables, as the increase in the number of charge-discharge capacity gradually decreased until the last scrap. Since different brands of laptop batteries less common, but the price of the original battery is very high, the cost of replacement batteries not small, is often several hundred dollars. In fact, any laptop battery scrap, mainly batteries inside damaged, if we can move their hands, the replacement of batteries, so basically for the cost of the battery directly in half. Here’s look at the core of the process for you.
First, the purchase of new batteries
At present, the market and on-line computer will be able to buy new batteries (Figure 1), common brands such as Sanyo, Sony, Samsung, LG and so on. Cylindrical and square cell is divided into two broad categories. Cylindrical batteries is currently the most widely used type of batteries, with a capacity of more than 2400 ~ 2600 milliamperes in between. Square multi-batteries used in portable models (such as the ThinkPad X200), the lighter, with a capacity of more than 1800 ~ 2200 milliamperes in between. Need to buy their own after the number of batteries, people pay to spend, look for businesses with spot welding cell batteries in accordance with the method of connecting the new battery will be good to welding.
Small knowledge:
From the life of batteries, the Japanese brand of the longest, followed by South Korea Department of brands, China Taiwan and the mainland areas of production, the worst batteries. At the two ends of the new batteries should not be any welding marks, otherwise, it is the old batteries. Choice of high capacity batteries, high capacity battery life longer. The higher capacity batteries, the price more expensive, should be their actual needs, select the applicable capacity inspiron 500m battery.
Second, open the battery case
Gently with a small hammer percussion battery casing so that casing loose percussion shell strength can not be too large, so as not to crack the battery case. Font with a small screwdriver inserted into the battery casing seams, and then gently lever the battery casing. Do not put too much attention, too, otherwise the battery casing easily cracked.
Third, removal of old batteries
Open the battery cover, we will be able to see the old batteries and management of the chip (Figure 2). Management chips cut with the old wire between the batteries as much as possible to stay in the management of the chip lead long enough to facilitate the installation of new batteries. Cut the wire, the old batteries can be removed from the battery.
Small knowledge:
Management chip in the battery storage of the relevant parameters, and its battery is fully charged in a timely manner to cut off when the charge current to protect the rechargeable battery in order to avoid an explosion over the fire; put in the battery when finished in time to prevent the battery discharge, the battery will not be because of and end-of-life take-off.
Fourth, the installation of new batteries
To have good welding Add new batteries in the battery and wire management on a chip soldered to the ends of the latitude d520 battery.
Tips:
When the welding wire is negative, the Government must not be mistaken, or else will be burned down the entire battery. If the management of the chip has been locked, it should be to unlock the battery repair shop.
Fifth, the battery shell bonding
In the battery case seams painted with a layer of glue 502, and then pry the battery shell re-glue.
Tips:
Glue the battery casing can be tied up some rubber band, so that the battery shell may be more firmly bonded.
Sixth, the battery capacity calibration
To replace the batteries a good re-install the battery to the notebook computer, the battery fully charged, unplug the power adapter and then let the battery discharge until the latitude d820 battery power Automatic shutdown after release date, followed by electricity with the power adapter. After several correction, you will find that the battery power has been restored to a new level purchased.
