1. Unbalanced

Repair method: Find the battery with the capacity, voltage, self-discharge, battery internal resistance and so on.

2. Loss of water

Repair method: Open the cover above the battery. Some battery covers are ABS glued, and some are snap-fit connections. Some are skateboarding. Be careful not to damage the cover when opening the cover. At this time, you can see the rubber caps of the six exhaust valves. Open the rubber cap to expose the vent hole, and the inside of the battery can be seen through the vent hole. Some battery exhaust valve bases can be unscrewed, and the exhaust valve base can be unscrewed without opening the rubber exhaust valve. Some batteries have some filler around the rubber cap. Open the cover and light it with your hand to see if there is any dryness inside the hole, that is, if the battery loses water. The plates of the battery are wrapped in white fiberglass cotton and should be wet under normal conditions. The distilled water is sucked into the battery through a vent hole. The water-filled battery is covered with a gas-permeable covering to cover the vent hole to prevent dust from falling into the vent hole. It is best to use medically distilled water. The principle of hydration is to keep more. Not enough can be added, the more the acid weight is reduced, the battery capacity will be insufficient. Inexperienced people can master 5mL per well. It is best to look at the plus, wet, sparkling, watery. The wetness is just right, the sparkling crystals are much more, and the water is too much.

Special note: The hydration tool uses straws such as glass and plastic. Medical disposable syringes are recommended for ease of use and ease of metering. The hydrating tool cannot use any metal-containing appliance. The syringe should be pulled out of the metal needle and used after a plastic tube.

3. Sulfation

Repair method: The vulcanized battery is repaired with the Kedi repair instrument, and the fuzzy digital control theory is adopted. By measuring the state of the battery, the positive and negative variable frequency particles are continuously emitted while charging and discharging, and the battery is removed in 10 to 20 hours. Hard lead sulfate that crystallizes.

4. Plate softening

Repair method: After discharging the battery to 10 or 5V, the battery is deeply discharged for 1-5 hours. Then use an activator to activate the repair.

5. Short circuit

Repair method: water battery, you can punch holes clearly, get the short-circuited lead powder out! Electric vehicle battery, you can quickly short the positive and negative poles, burn the short circuit!

6. Open the way

Repair method: 100A detects the battery voltage 0V as an open circuit. Using a single measurement method, the open circuit is measured and soldered.

Use a multimeter to measure where the battery is open!
