Electrolyte Dilution: Water entering the battery can dilute the electrolyte, reducing its effectiveness and impairing the battery’s ability to hold a charge.
Corrosion: Water damage can lead to corrosion on the battery terminals and connections, increasing resistance and causing the battery to discharge faster.
Short Circuits: Water can create pathways for electrical currents to flow where they shouldn’t, leading to short circuits that drain the battery.
Internal Damage: Water infiltration can damage the internal components of the battery, affecting its overall performance and reducing its capacity to hold a charge.
Continued Moisture Exposure: If the battery remains exposed to moisture, it can continue to discharge over time, even after the initial water damage has occurred.
If you experience rapid battery drain after water damage, it is advisable to seek professional assistance or consider replacing the battery if necessary.
