Question: What Happens If You Have A Dead Cell In Your Car Battery??

If the battery cannot reach higher than 10.5 volts when being charged, then the battery has a dead cell.

If the battery is fully charged (according to the battery charger) but the voltage is 12.5 or less, the battery is sulfated.

If your battery cannot even reach a full charge, consider it bad.

How do you fix a dead cell in a car battery?

Procedure for Reconditioning Your Car Battery

  • Heat 1/2 quart distilled water to the boiling point, or about 150 degrees.
  • Using baking soda and clean water to prevent contamination, clean outside of the battery.
  • With the help of a screw driver, carefully remove the covers from the battery cells.

Why do battery cells die?

When the active material in the plates can no longer sustain a discharge current, a battery “dies”. Normally a car (or starting) battery “ages” as the active positive plate material sheds (or flakes off) due to the normal expansion and contraction that occurs during the discharge and charge cycles.

What causes a car battery to die quickly?

Some of the most common reasons for a car battery to die repeatedly include loose or corroded battery connections, persistent electrical drains, charging problems, constantly demanding more power than the alternator can provide, and even extreme weather.
