Cause | Elimination Method |
Battery discharge while driving | |
Alternator drive belt slip | Adjust belt tension |
Excessive contamination of the battery surface | Clean the surface of the battery |
Damage to the insulation in the electrical system (discharge current more than 1 mA with disconnected consumers) | Locate the current leakage and repair the damage |
Connection of new consumers by the car owner in excess of allowable limits | Turn off new consumers of electricity |
Faulty generator | Check the generator |
Electrolyte contamination with foreign impurities | Charge the battery, drain the electrolyte, flush, refill with fresh electrolyte and charge the battery again |
Short circuit between plates | Replace battery |
Electrolyte level below the upper edge of the plates | Restore normal electrolyte levels |
electrolyte on the surface of the battery | |
Elevated electrolyte level leading to sloshing | Set normal electrolyte level |
Electrolyte seepage through cracks in the case | Replace battery |
Electrolyte boiling due to very high alternator voltage | Check the connection with «weight» housing of the voltage regulator and the correct connection of wires to it; adjust or replace voltage regulator |
Electrolyte boiling and battery overheating due to plate sulfation | Replace battery |
