Introduce the activation problem of lithium battery

Analyze why the lithium battery is the same mobile phone, the same battery, the standby time is long, some people start the standby time for a short time, it may be that the battery contact is not fully activated, although most of the Samsung battery activation process is in the factory, but not Completely, so it will be used for a period of time, the standby time is long, personally, I have tried many including any activation method to charge for 12 hours online, but if it does not show in the following way: because most of the water dispenser seats are fake , So we still use the original clothes to directly charge more insurance, and the effect seems to be a little better to charge directly. First of all, the internal power consumption, which is a virtual power, should not be used. With the battery, usually 1 to 2 hours, if the phone will be full of flash, it can not be pulled down immediately, let him charge more appropriately, usually about 10 minutes, then dial the charger, 10 seconds again from the beginning, This phone will charge the flash again, and it will glow after 10 minutes of full charge, instead of unplugging it immediately. After unplugging, it may be a low battery warning and renewing the battery when the battery is running normally. The first 3 times like this, the root end can activate the cell completely. Responsible for 12 hours of good results. After charging, you must be able to use the relevant instructions to check the voltage, generally between 4.1v-4.2v, so that the charge is fully charged! My friend bought this 8100 in October 2000. The battery has been broken for more than a year. The remaining power is always 0%, and the charging indicator is always green. A friend once used my analytical discharge method and took the risk of shorting the positive and negative poles. Originally scared, waiting for sparks to fly, the silent character. Find a multimeter, the voltage is zero. Then use the current of the multimeter to stop the discharge, from high to low, the purpose is no current. At this time, the author is wondering, is there a circuit inside the battery pack? Then when I choose Dr. Dead Horse, turn the battery over to complete the DIY. The battery pack consists of 8 Panasonic lithium batteries, each of which is no better than the usual. 5 batteries, two smaller circuit boards. Every two batteries are connected in parallel and then connected in series. Use the voltage range of a multimeter to measure the two poles of a set of parallel batteries, the voltage is about 4V. Measure with the current block (2.5A) again, touch it quickly, the pointer hits the far right, and you see sparks splashing. It seems that these two batteries are dead! In this sequential measurement, the last two batteries in parallel have neither voltage nor current, and the resistance is infinite, which seems to be the problem. After connecting the two welding lines, use the battery, and then use the discharging method and the high-voltage shelling method to deal with, the application has no response. Faced with the remaining 6 good batteries, I think, can they replace this burden? Use a soldering iron to remove one of the batteries and place it in the final position. In this way, four batteries are connected in parallel with each other and connected in series with the other two batteries to obtain a voltage of about 16V. Then remove the two used batteries, close the cover, and install the machine. First, charge it for about 1 hour and 8 minutes in the off state. The charging indicator will change from orange to green. Turn on the power, turn on the meter, the remaining capacity of the flash battery is 23%! The flash is charging! It seems that the charging indicator is incorrect. Continuous charging under startup conditions (the charging indicator is always green at this time). After charging for about 20 minutes, the flash power is 100%. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
