My battery has corroded at the red and black connectors

Motor Vehicle Maintenance & Repair Asked by Aditya Sridhar on June 20, 2021

As seen in the picture my batter in a 2012 Toyota Camry has this white salt-like build up around the bracket that holds the battery in place. However, there is no tea build up in the red and black terminals.

Another thing to note is that the white substance has spilled over onto the base of the battery as well.

Is this a sign of a leak? Should I be replacing the battery or just clean the corrosion and jump start the car?

Any help is appreciated!

One Answer

Rinse with plenty of water then sprinkle on baking soda . The white is zinc and iron sulfate .Caused by sulfuric acid ,liquid or vapor, getting out of the battery . No practical way to stop it. I would continue to use it but a new battery will fix it. You may need new nuts and bolts for the hold down and the terminal connections will need a good cleaning when you get a new battery.
