How to Charge a Dead Battery in Trumpchi GS4?
3 Answers
There are three methods to restore the battery power of Trumpchi GS4: pulse repair method, full charge and discharge repair method, and water replenishment repair method. The following is an introduction to the relevant content: 1. Pulse Repair Method: The best method to eliminate sulfation in batteries is the pulse repair method. When repairing the battery, the instantaneous pulse voltage is generally between 60V and 300V, depending on the functional requirements of the product. For products aimed at extending battery life, the pulse voltage should not be too high. For products specifically designed for battery repair, the pulse voltage can be higher (if the pulse voltage is too high, it may damage the battery plates). A higher pulse voltage results in a shorter repair time, while a lower pulse voltage leads to a relatively longer repair time. Although the instantaneous pulse voltage is high, the average voltage is not, making it safe and harmless to humans. 2. Full Charge and Discharge Repair Method: This method involves fully charging the battery and then completely discharging it to repair the battery. It is mainly effective for mildly damaged batteries and can also activate the deep-seated active materials in the battery, improving its capacity. For batteries with mild sulfation or high internal resistance, the key is to ensure the discharge is thorough, with each individual cell being fully discharged separately. Performing this method 1-2 times can generally enhance the battery's capacity. However, the full charge and discharge repair method should not be used frequently—at least once every six months and at most once every three months. 3. Water Replenishment Repair Method: For batteries suffering from 'water loss,' replenishing water can repair them by diluting the concentrated sulfuric acid to facilitate normal electrolysis. The method is simple: open the battery's top cover to reveal six round holes, inject a certain amount of distilled water into each hole, and soak for more than 24 hours. Only distilled water should be used for replenishment, as other types of water, including purified water, contain various metal molecules that can cause self-discharge and damage the battery.
Last time my Trumpchi GS4 had a dead battery, I simply used a charger to fix it—pretty straightforward. First, make sure the car is parked in a safe location and turn off all electrical devices. Then, purchase a proper car battery charger, which you can find online or at an auto repair shop. When connecting, be careful not to reverse the positive and negative terminals—attach the red clip to the positive battery terminal and the black clip to a grounded metal part of the car frame. Charging time depends on the battery's discharge level, but generally, 6 to 8 hours should suffice. If you're in a hurry, you can ask a friend for a jump-start and then drive on the highway for about half an hour to let the alternator recharge the battery. To avoid this situation, I've developed the habit of turning off the headlights before shutting off the engine. If the battery is aging, replace it early to save yourself the hassle of frequent issues.
I think dealing with a dead battery requires caution, as it involves electricity. When my own GS4 had a dead battery, I directly opened the hood to check if the battery was swollen or leaking. If there were any signs, I definitely wouldn't force a charge and would go to the 4S store for a replacement. If there were no major issues, I would then use a charger for a slow charge, setting the voltage to 12 volts, ensuring not to exceed it to avoid damaging anything. Jump-starting is also an option, but first, make sure the other car's battery is in good condition, the clamps are secure, and sparks don't fly. Regularly, I measure the voltage to ensure it stays above 12.6 volts. If the battery frequently dies, it's best to check the alternator or circuit issues to prevent further trouble.
