The white, flaky stuff that can build up around your RX450h’s battery terminals is known as corrosion.

Corrosion can affect the flow of electricity between your battery and the electrical system in your RX450h, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.
