Battery Corrosion

[cityofrain]

So I have a unique situation where I cannot find the wire / part that goes to the pos battery terminals. This isn’t the battery wire harness which I have and am about to replace but this is the connector shown in the picture. However mine is corroded and is most likely done for. Does anyone know what part that is? Is it replaceable? It’s circled in red in the attached photo.

I purchased the replacement starter cable part # DB5Z-14300-E but this didn’t come with the connector / harness I need. Any help will be greatly appreciated.

Those two red wires look to be something after market.

Just spray it with terminal cleaner, scrub it with an old tooth brush or your wife's current toothbrush, hose it off, blow it dry and coat with some reg grease or dielectric grease if you have it

Did you search the PN molded into the receptacle that's visible in your first pic? Or look for a PN molded into the green connector you circled?

Never use dielectric or chassis or thermal grease or anti-seize where you want electricity to flow. Use electrical grease (which is NOT conductive). All that corrosion indicates that the battery case is leaking around the post. Use the cheap common felt washers to slow it down, but shop for a better battery.

Welcome to the Forum.
Your picture looks exactly like the one posted by Medic of his 2015 back in 2017.

Corroded Battery Terminal / Cable

Does anyone know what causes this? I noticed a few threads where several people had to replace very corroded positive terminals and I just ordered a replacement for mine. It seems to accumulate a green substance that covers the entire terminal. I have been cleaning it off with baking soda. I...

Exactly why you use dielectric (or just any plain old grease) to coat the terminals, AFTER you connect and tighten them down. You don't want conductivity or corrosion on the outside of the terminals

Electrical grease, often referred to as conductive grease, enhances electrical connections by improving conductivity, while dielectric grease is an insulating compound that protects connections from moisture and corrosion but does not aid in conductivity. It's important to use each type appropriately based on the application to avoid issues with electrical performance.
Or better yet, battery terminal protector

So if you have to attach a charger every now and then due to limited driving, you'd use Electrical Grease. Correct?

You'd be better off mounting a cheap trickle charger (battery tender) in the engine bay and have it permanently connected at the battery posts. The Schumacher unit below was my go to, but they've become a little spendy. You can find a decent alternative for about $20, or I also use the Chinesium cheapos ($5) from Ebay with no issues. All my vehicles are low use and all have under-hood trickle chargers that are plugged in 24/7. Also extends battery life from avg 7 years to 10+ years.

Re: Conductive Greases
Note that you do not want to use such conductive grease in a multi pin connector as just it smearing as you plug it in could bridge or short a connection. That's why I would never use it on anything except maybe battery terminals. Probably also why the industry standard is dielectric grease.

Bulb Grease vs Dielectric Grease

Does anybody know if bulb grease is conductive to electricity? I know Di-Electric grease insulates electricity. I was planning to scrape away paint front where the engine-chassis ground attach, but would like to protect from rusting. The car has been sandblasted, coated with epoxy primer and...

I have a charger that doubles as a maintainer but the placement of the battery is a little problematic. In order to attach the pigtails I would not be able to snap the cover into place and since the vehicle is a lease, I don't want to modify the cover. I'll just make do with charging the battery every now and then as I've done with all my other vehicles. Also, I've never had a corrosion issue. Thank you for the advice.
