how long is it for the first time to charge your laptop batteries?
As the current prices of laptop batteries are generally not cheap at 600 to 2,000 yuan, the price is high, many often use the laptop battery headache for the user. In fact, a battery life does not mean the end of the battery completely useless, because only the internal battery pack or failure caused by aging, and the circuit is part of the general well-so long as you are willing to play some of the DIY spirit you can not save Less money. To replace their laptop batteries when they must have a knowledge of physics and a little bold but cautious, dare to do that is to open the battery, hands-on time to be careful not to hamper the part of the circuit or you do not want to buy all new to die. In fact, this is very simple, open the battery cover you can see that after the internal battery and circuitry, when you examine your battery's serial, parallel way (what? You do not know how to see. ) And the type of battery used, the type and number, they know to go after the electric market to buy batteries required for a single battery, a lithium battery in general Monomer 20 to 35 yuan. In the single cell to buy should be noted that certain buy the same brand, same model, the same batch of products, as a number of experiments show that the battery string them together using single cells as a result of subtle differences make a single battery failure in advance In turn affect the entire battery pack, so we must pay attention to. After the battery, of course, is to buy back the old batteries from the battery pack in power-by-iron welding and then to a new welding as is back, but would like to remind you that the electric iron to a higher temperature, so that the process of welding can be used Very short period of time and the battery contacts, not overheating as a result of which will be battery life and reduce the performance. Finally, the shell with 502 such letters glue, mounted on the back notebook to test if there is no problem, then congratulations you're done!
