Can the battery be charged immediately after adding water?

The battery should not be charged immediately after adding water (distilled or purified water). It needs to sit for 1-2 hours before charging. This is because the newly added water needs to fully mix with the original battery fluid (dilute sulfuric acid) to ensure the quality of the charging process. Below are the precautions for charging the battery after adding water: 1. When removing the positive and negative terminals, always follow the "negative first, then positive" sequence (the reverse of the installation order). This is because after connecting the negative terminal, it essentially completes the circuit for the car. If the positive terminal is connected last, there is a risk that the wrench (which is conductive) might accidentally touch the car's metal parts while tightening the screws, effectively connecting the battery's positive and negative terminals. This can not only cause a short circuit in the car battery but may also lead to sparking in severe cases. 2. It is best to avoid overcharging the battery. Although the current generated during charging is not very high, prolonged boiling of the electrolyte can cause fine particles on the surface of the active material to detach and, in severe cases, lead to oxidation of the grid, resulting in loose separation between the active material and the grid.
