Repair method: pry open the cover above the battery. Some battery covers are glued with ABS, and some batteries are connected with buckles. Have a plenty of skateboards. Be careful not to damage the cover when prying it open. At this time, you can see the rubber caps of six exhaust valves. Open the rubber cover to expose the vent hole, through which you can see the inside of the battery. The exhaust valve seat of some batteries can be unscrewed without opening the rubber exhaust valve. Some batteries have some fillers around their rubber caps. Open the lid and shine it with a flashlight to see if there is any dryness in the hole, that is, if the battery loses water. The electrode plate of the battery is wrapped with white glass fiber cotton, which should be wet under normal circumstances. Inhale distilled water with a dropper and inject it into the battery through an exhaust hole. Cover the vent with a breathable barrier to prevent dust from falling into the vent. It is best to use medical secondary distilled water. The principle of water replenishment is less than more. If it is not enough, it can be supplemented. If it is too much, the proportion of acid will decrease and the battery capacity will be insufficient. Inexperienced people can master 5mL per hole. It's best to see Canada. It's wet, shiny and watery. Just wet, shiny and watery.
Special note: glass, plastic and other straws are used for water replenishment tools. It is recommended to use medical disposable syringes for easy use and measurement. Do not use any metal-containing instrument as a hydration tool. The syringe should be used after the metal needle is removed and the plastic tube is put on.
3. Sulfation
Repair method: Repair the vulcanized battery with pulse repair instrument, and use high voltage (30V-50V) pulse (8330HZ) and low current (1%-2% of the battery's nominal capacity) to remove the crystallized hard lead sulfate 10 to 20 hours.
4. Plate softening
Repair method: After the battery is discharged to 10.5V, deeply discharge it with a light bulb for1-5h. Then use an activation instrument for activation repair.
5. Short circuit
Repair method: water battery, you can make the hole clear and get the short-circuited lead powder out! The battery of an electric vehicle can quickly short-circuit the positive and negative poles and burn them to the short-circuit place!
remove barriers
Repair method: 100A detected that the battery voltage 0V was an open circuit, and the open circuit was measured by single measurement method and welded.
Measure the battery open circuit with a multimeter!
