Cure For Battery Terminal Corrosion

We've had 3 Tundras in our family along with several Toyotas, Scions and the Tundras ALL suffered from inordinate hold-down and terminal corrosion repeatedly. The other Toyotoa problems, not so much.

As others have mentioned, battery cleanliness is paramount in helping stave off this problem, but also not over-filling the battery to avoid corrosion caused by excessive off-gassing is helpful.

In the case of the Tundras being more prone to this than our other Toyota products, since its been all 3 of them which have had this problem Im convinced the grounding system in these trucks is different enough than their cars (weak or poor grounding) that despite best efforts terminal corrosion on Tundras is not preventable.

You can PREVENT BTC by coating the terminals with a thick layer of wheel bearing grease.

My daughters car had corrosion all over the battery, all over a nearby computer, and all over the nearby fusebox. The terminals had to be replaced as did the hold downs by the delaer (shes rich! )

Now a year later her terminals are good and clean of corrosion with a good coating to wheel bearing grease on them!

I thought her husband bought her a Toyota SUV to replace the Camry (re 'winter safety' ?). Different daughter, or just kept the Camry and the SUV ?

Youre right he did.

But that was some time after the corrosion issue was repaired by the dealer.

Don't worry Im not making any of this up!
