Car battery broken plate seen through the hole

Post by Dumindu » Thu May 21, 2020 9:16 am

My car is a Toyota Tercel 1987 DX Wagon.

Car has a 65amp battery with 6 cells.

When attempt to start, car only has the sound of the solenoid. Doesnt start.

When I charge the batter, It charges upto 13.6 V.

After attempt to crank, Battery voltage drops to 10.6V and that is kept steady. It dosnt comes back to normal value back.

When charging the battery, Only in 5 out of the 6 cells bubbles comes. One doesnt have at least any shake in the fluid.

Acid specific gravity is normal in all the cells.

I had tried to charge the battery with 2A charger for 24 hours. Result is same.

When I closely inspect inside the weak cell through the hole, one of the thick ash colour plate is broken into 2 at the middle. One part is lifted slight. It can be draw upward with forceps.

What can I do?

What happens if I remove the Ash color plate by lifting it and break into pieces?

sounds like you have a dead cell. you should try dipping the probe of your volt metter across each of the adjoining cells, into the liquid only (DO NOT ALLOW THEM TO TOUCH THE METAL PLATES!). each adjoining cell should give you 2.2 volts, I bet the bad one gives less than 1 v.

I do not think there is a way to fix it a damaged cell. Most people will replace the battery. there are places that rebuild batteries by removing the top, and replace damages or scaled plates. and than reassembly and replace the battery acid (liquid). But I would not attempt that myself. you might find something on youtube that tells you how to do that, good luck.

Thank you very much Mr.Petros for your valuable answer.

Should I check the voltage difference after attempt to crank?

Before attempt to crank (just after charged),there are 2.2V - 2.3V in-between good cells. There is 1.9V between the bad cell and the adjacent good cell.

After attempt to crank, there are 2.1V in-between good cells. There is 1.8V between the bad cell and the adjacent good cell.

After cut and examine the cell, it could be noticed a heavy damage to the plates.

I accidentally charged the battery with closed caps. I could be the cause for such a damage to the 1 1/2 year old battery.

Replaced the cell with new plates and repaired.

Now battery works fine.
