We have had our 2012! since new and it has just turned over 100,000 miles. I have dealt with battery corrosion issues since early in our ownership. The battery connections themselves, the ground attachments(poor though they are)and the starter connections have all had strong evidence of it. I have continually fixed it but just wondered if any of you other owners 0f older Souls have had this problem. I think we are on the third battery and battery life is fine. And checking the charge rate shows no dramatic level of overcharging. It not really a problem, just an annoyance.

I haven't had any corrosion on my 2014. I'm on 3rd battery as well.
From the interweb:
Car battery corrosion is primarily caused by a chemical reaction between battery acid (sulfuric acid) and the metal terminals, leading to a buildup of white, green, or blue powdery deposits. This reaction is often accelerated by factors like overcharging, electrolyte leakage, and environmental conditions.
Here's a more detailed breakdown:

From the interweb:
Car battery corrosion is primarily caused by a chemical reaction between battery acid (sulfuric acid) and the metal terminals, leading to a buildup of white, green, or blue powdery deposits. This reaction is often accelerated by factors like overcharging, electrolyte leakage, and environmental conditions.
Here's a more detailed breakdown:
1. Chemical Reactions:
- Sulfuric acid and metal interaction:
The sulfuric acid in the battery can react with the metal terminals, especially when exposed to air and moisture, forming corrosive byproducts.
- Electrolysis:
Electrolysis, a process involving electrical currents between different metals, can also contribute to corrosion at the battery posts.
- Overcharging: When a battery is overcharged, it can overheat, causing the electrolyte to expand and potentially leak through the vents, leading to corrosion on the terminals.
- Battery age: As batteries age, the seals and connections can degrade, increasing the likelihood of leaks and corrosion.
- Overfilling: Overfilling the battery with battery water can cause the electrolyte to overflow and corrode the terminals.
- Poor connections: Loose or corroded connections can create electrical resistance, generating heat and potentially causing further corrosion.
- Moisture and humidity: Moisture can accelerate the chemical reactions that lead to corrosion.
- Environmental conditions: Extreme temperatures, especially heat, can exacerbate corrosion.
- Overcharging: When a battery is overcharged, it can overheat, causing the electrolyte to expand and potentially leak through the vents, leading to corrosion on the terminals.
- White, green, or blue powdery deposits: This is the most common visual sign of corrosion on the battery terminals.
- Reduced starting power: Corrosion can interfere with the flow of electricity, making it harder to start the vehicle.
- Flickering lights or other electrical issues: Corrosion can affect other electrical components, leading to various problems.
- White, green, or blue powdery deposits: This is the most common visual sign of corrosion on the battery terminals.
Hey plymouthcranbrook, are you also a member of Allpar, like me? Your user name looks familiar.
2012+ No corrosion problems at all. 173,000+ miles, third battery. First replaced in 2016 at 87,000 and second in 2020 at 130,000. Do you live in a coastal, salt water environment? Northern climate? I'm in the southeast. My worry is heat.
Same here, Tom, except I have 179,000+ on my 2017 and have only replaced the battery once. My OEM battery lasted about 7 years! The one year warranted battery I got from Walmart has been holding up quite well. And at about $65 out the door with core exchange, I don't mind if I have to replace it in another 2 or 3 years. I'm on a fixed income and can't afford $150 for a frigging battery. I'm about an hour and a half away from you in Alabama.
Hello everyone. Apologies to everyone for taking so long to get back here. I appreciate the input since it seems like mine is an outlier in the corrosion dept. I live north of Chicago and would blame the winters but the last several years we haven't had much snow so salting is at a minimum. I keep the battery clean and the charging by the meter is right in the ball park. I seem, to have it under control using the post rings and anti corrosion spray. time will tell. oh, i do stop by Allpar on occasion but my interest in Chryslers is mostly pre 1990 or so,
The more complicated cars are getting, I'm longing for the days of my 60's and 70's vehicles. My 1969 Dodge Polara was one of my most favorite cars. 383, 2 barrel carb, automatic with a/c. I installed a fm converter and an 8 track player and was in BUSINESS. 13 people made it to a Lynyrd Skynyrd concert in that car. I had 9 inside and 4 in the trunk. The 4 that rode in the trunk found another way back to the dorm!
They did. Keep in mind also that the trunk on my land yacht was 6 feet wide too. I could take that sucker camping and sleep in the trunk if I'd had to.
Thanks. Sometimes those land yachts would come in handy.
That's funny. I also had a 77 Monaco. I needed a loan for a van to start a delivery business and my Dad said he'd give me the money if I gave him my car. So, that's what I did. 81 Dodge Ram 1/2 ton van. And the rest is history. Well, to me anyway.
