Why does the battery quickly run out of power after being fully charged.
The battery of the motorcycle is only fully charged, and after just a few uses, it has run out of power; "Or a fully charged battery runs out of power after a few days, which is due to the severe vulcanization of the battery's plates.".
When the electrode plate of a battery is severely vulcanized, a thick layer of white lead sulfate crystals will form on the electrode plate, which will reduce the active substances involved in the chemical changes of the battery. At the same time, this layer of crystals will hinder the infiltration of electrolyte, reducing the capacity of the battery, making the battery fully charged quickly, but the capacity is not large, so it will soon run out of electricity during use. This situation is commonly referred to as the vulcanization of the electrode plate, and the main reason for the vulcanization of the battery is that the battery has been undercharged for a long time or has been placed for a long time under the condition of partial discharge.
If serious vulcanization is found on the battery plate, first discharge the battery, pour out the electrolyte, and then inject about 1.15 electrolyte with a smaller density. Charge with a current of 1/15 of the battery capacity until bubbles emerge from the electrolyte, and then reduce the charging current. When bubbles in the electrolyte rise sharply, pour out all the electrolyte in the battery, and then add electrolyte with a density of 1.27-1.29, Use a small current to charge, fully charge, and then discharge and recharge. After several repetitions, the battery will generally return to normal.
"When severe vulcanization occurs, distilled water can be added and charged using the same method. This way, lead sulfide will be dissolved in distilled water under the action of an electric field, forming a very dilute electrolyte. When a large number of bubbles emerge during charging, the battery will be discharged, discharged, and recharged repeatedly. At this time, it is necessary to check the density change of the electrolyte in the battery. If the electrolyte scale no longer rises, the capacity of the battery will also increase to more than 85%,", Pour out the solution from the battery and inject new electrolyte into the battery.
