1. Open the battery cover and take off 6 safety helmets.
? 2. Fill each hole with distilled water with a syringe. If 1.28 standard electrolyte is added, the plate may burn out due to excessive acid dissolution. For example, we eat hot pot, why will eat more salty, that is, when the water evaporates, the salt will not evaporate through the water steam, the same reason, the acid in the battery will not be evaporated, the missing is water, so we just add about 20-30ml of distilled water in each hole.
? 3. After filling up, let the battery rest for half an hour, so that the sponge body around the plate fully absorbs water. Then use resistance discharge, put the battery in the electricity, all put out, no resistance, you can use a 12v bulb instead, such as: motorcycle headlights, car turn signals can be used, as long as it can discharge to 0v. How to judge the battery is close to no electricity, cement resistance discharge at the beginning of the resistance body hot, slowly gradually not hot, then the battery is out of power. The light bulb, but also directly, as long as the light slowly does not light, it shows that the battery discharge is over, the discharge time depends on the capacity of the battery discharge, we can first ride the battery to no power and then maintenance, which can shorten the discharge time.
4, after the end of the discharge to charge the battery, conditions can be used pulse charging, because the pulse charging method can effectively remove the vulcanization of the plate, improve the capacity of the battery. What you don't have can be replaced with a car.
5, after the charging is completed, use the syringe to draw out the excess water in each hole. A total of six holes, step by step to complete.
6, cover the cap and cover, you can load the car.
one
Rubber repair. Use a clean eraser or other material cleaning tool to gently wipe the metal contacts on the lithium battery and the metal contacts on the mobile phone to help the charging condition and power durability.
two
Freezer repair will be used to automatically shut down the old mobile phone lithium battery with plastic wrap firmly wrapped in the freezer layer,48 hours later, take out the battery to remove the six layers of paper film wrapped. Let it cool for a while, then charge it.
three
Discharge repair. This repair method is to completely discharge the lithium battery that is close to being scrapped, and then recharge it to activate the battery. The specific method is: deep discharge of the mobile phone, that is, by depleting the internal electrical energy, to achieve a deeper degree of recharging, which requires the use of some unconventional methods.
