Laptop battery is a consumable, will increase as the number of charge-discharge capacity gradually reduced and eventually scrapped. Since different brands of laptop batteries less universal, but the price of batteries is very high, the cost of replacing the battery Compaq Presario 2500 battery(compaq 2500 battery) may from time to small, frequently is several hundred dollars. In fact, any laptop battery scrap, mostly inside the batteries is damaged, if they can move their own hands, replacement batteries, then replace the battery directly to the cost of essentially halved. Here's take a look at the whole process of changing the core bar.

First, buy new batteries

The current computer market and the Internet are 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 types of batteries, the capacity more in between 2400 ~ 2600 milliamperes. Square batteries used in portable multi-models Compaq Presario NX9010 battery (such as the ThinkPad X200), on lighter, more capacity between 1800 ~ 2200 milliamperes. To buy their own, after the number of batteries needed to spend points were wages, looking for businesses in accordance with the spot welding cell batteries new battery connection method can be welded well.

Small knowledge:

Life from the batteries run, the longest laptop battery Japanese brands, Korean-brand, second, and China Taiwan Area and the Mainland, the worst production of batteries. The two ends of the new batteries should not have been any traces of welding, otherwise the old batteries. Choice of high capacity batteries, the battery capacity of the high-life longer. The higher capacity batteries, the price more expensive, should be their actual needs, select the applicable capacity batteries.

2, open the battery case

With a small hammer and gently tap the battery shell, so shell loose percussion shell strength can not be too large, so as not to crack the battery case. Font with a small screwdriver into the battery casing seam, and then gently leveraging the battery casing. Note Do not force too much, too fast, otherwise the battery casing is easy to Compaq Presario NX9000 battery fragmentation.

3, removal of old batteries

Open the battery case, we can see the old batteries and management chips (Figure 2). Cut management chip and old batteries between the wires, as much as possible in the management of chips left on long enough wire to facilitate the installation of new batteries. Cut the wires, the old batteries can be removed from the battery.

Small knowledge:

Management chip stored in the battery-related Hp F2299A battery parameters, and its role is to full power in the battery charge current when the cut off time to protect the battery to prevent overcharging explosion fire; in the battery to prevent discharge finished in time for the battery power to continue to discharge the battery because it does not make had put the scrap.

4, installation of new batteries

To have a good weld in the new batteries into the battery, and to manage on-chip wires soldered to the battery ends.

Tips:

Welding wire should never mistake the positive and negative, otherwise it will burn the battery block. If the management chip is locked, it should be to unlock the battery repair shop.

5, adhesive battery shell

In the battery casing seam 502 coated with a layer of glue, and then pry the battery under the Hp F3172A battery shell to re-glue.

Tips:

Glue the battery shell, you can bundle some of the rubber band, so that the battery shell may be a more solid bond.

6, corrected battery capacity

The replacement of a good battery to re-install the batteries into the notebook computer, the battery is fully charged, then unplug the power adapter to the battery discharge, until the battery is automatically shut down power until the end release, draw a line on the power adapter is fully charged. After several calibration, you will find that the battery Hp Pavilion ZT1000 battery power has been restored to a new level of the bought.
