Battery activation method
1, the use of high current charging, so that large lead sulfate crystals produce negative resistance penetration to dissolve the method. In the experiment, it is found that this elimination vulcanization can only obtain temporary effect, and will bring about increased water loss and positive plate softening problems during the elimination of vulcanization, causing serious damage to the battery life, which is not easy to use.
2. Negative pulse
This method has been applied for more than 30 years of history, the principle is to add a negative pulse in the charging process, which has an effect on reducing the temperature rise of the battery, but the repair effect of \"vulcanization\" is not obvious, the repair rate is 20%, and the current use is more, which is a eliminated product, and the frequent price is about 1300 ~ 1600 yuan.
3. Add active agent
The use of chemical methods to eliminate lead sulfate crystals is not only costly, but also increases the internal resistance of the battery, and also changes the original structure of the electrolyte, and the use period after repair is short, and the repair rate is about 45%.
4, high frequency pulse
The lead sulfate crystals were converted into reversible lead sulfate with fine crystals and high electrochemistry by pulse wave, so that it could normally participate in the chemical reaction of charge and discharge, and the repair rate was about 60%. Better effect than negative pulse. However, due to its long repair time, it takes more than tens of hours, or even a week, the efficiency is low, the serious \"vulcanized\" battery repair is not good, but the technology is simple, there are many manufacturers re-use, the market price is about 2000 yuan.
5, combined resonant pulse
Reasonable control of the front edge of the repair pulse, the use of high harmonics in the charging pulse and large lead sulfate crystal resonance method, in the repair process to eliminate the battery vulcanization, the use of this method can be used to repair the battery, the repair efficiency is high, the battery damage is small, greatly reduce the lead-acid battery pollution to the environment, so that the battery life is extended. Reducing the huge cost caused by battery replacement for users, so the prospect is broad. The disadvantage is that the equipment technology is complex, the cost is high, and the pulse front control and resonance technology are required. The market price of about -4 type (independent 4 charging and discharging) is 2200-3800 yuan, and -20 type (independent 20 charging and discharging) is 8500-15000 yuan.
If the battery voltage is too low, it is in a state of starvation, want to activate normally, the starved battery must use high voltage DC current, charging this charger is best to choose pulse charger, in high current and low current back and forth to act as activation, battery products are the most effective means, so activate the battery mobile must use pulse charging is the best choice, I hope my answer can help you.
1. Use the dismantling tool to carefully disassemble the mobile phone, remove the screws and iron sheets used to fix the connection between the battery line and the motherboard, pull down the battery line, and take the battery out of the warehouse through the easy pull tape.

2. Use the multimeter to measure the positive and negative electrodes of the battery according to the marks on the battery line and the corresponding test point on the main board. Usually, the battery line will mark the polarity of the contact with \"P\" and \"P-\

3. Plant tin at both ends of the two enameled wires, and weld one end to the positive and negative electrode solder joints of the battery line respectively. If there is no soldering iron, you can use a small sewing needle to connect the wire, and make a simple cassette, and clamp the positive and negative contacts of the wire.

4. Connect the universal charge to the plug-in board, and put the other two ends of the enameled wire (or wire) on the electrode contact plate of the universal charge, observe whether the universal charge indicator is in the charging state. If no charging is displayed, replace the enameled wire.

5, During the charging process, you can use the multimeter (DC) to measure the output voltage of the universal charge (the output voltage is slightly higher than the actual battery voltage), if the battery voltage reaches about 3.6V, you can end the activation, install the battery back to the mobile phone, and use the line charge to continue charging it.
The simplest way to activate the battery is as follows:

1: When we correctly distinguish the positive and negative terminals of the battery, adjust the adjustable power meter voltage to 4.2V, the current to about 1A, connect the boot line to charge the battery. The positive pole of the red pen holder of the power cable and the negative pole of the black pen holder of the multimeter of the power cable contact the positive and negative poles of the battery respectively. Note that the positive and negative polarity must not be connected to the wrong, the ammeter will have a current display after contact, charge for about 10 seconds, the battery will be activated, at this time with a multimeter to measure the battery voltage, you can reach more than 3V, then use the data cable to charge the battery, it can be normal.
The first activation method is to find a group of batteries of the same model as the primary battery, and connect it with this group of batteries that cannot be charged, so that the good battery discharge to the battery that cannot be charged, and after several cycles of parallel charging, there is a certain probability that the battery can be reactivated.
The second activation method is to use a small charger to charge the battery first, and then change the original charger to continue charging. For example, the battery that can not be charged is 60V, you can first charge it with a 48V charger, and then change to the original 60V charger for charging, so that there is a certain probability that it can be activated.
The third activation method is to try to quickly charge for one to two hours, and use a professional detector to see if the voltage is increased, if there is an increase, you can choose to continue charging with the original charger, so that the battery can be activated.
