I’ll start by admitting my setup here is quite... shoddy. The stock battery hold down+heat shield for these is hard to come by and I haven’t bothered sourcing one. Instead I used a piece of u-channel, painted and conformal coated it, and used a generic hold down kit. Then I slapped on some generic heat shielding as the battery sits right next to the exhaust manifold and turbo.
There were reasons for all of this just go with it.
Then I added an aftermarket disconnect because I was doing a lot of electrical work.
That said, I’m not sure I’ve ever seen the powdery stuff there before. Is acid leaking out of the covers? The corrosion under the positive terminal is blueish whereas the stuff around the bars is white.
I’ll go ahead and replace the battery, but what should I do to prevent his?
