My car is at the dealer for regular oil change and tire rotation, and they called to say the battery is all corroded, but they'll be happy to clean it off and put some anti-corrosion stuff on it for $59.00.

I declined their kind offer, but am now wondering if this is something I should seriously take a look at?

Is this really going to become a problem somewhere on down the line, or are they just trying to squeeze more $$$ out of me?

It'll become a problem when the terminals get too corroded and you cahn't get juice off the battery. In some instances i've seen this wear down an alternator. Because the battery isn't supplying ample juice from terminal clog.

 

It's a simple fix. You basically need a few dollars worth of stuff to get it done.

 

1. A nice, toothbrush sized wire brush. Cleant he terminals with this. Safety first, jbetty. One at a time on those + and - . Keep them separate!!!

 

2. anti-corrosion gel (or, TEO has the old school vas offering. Both work. Vas tends to collect gunk, however, while most made for application gels do not.

 

3. tighten the terminals up good.

 

4. Profit.

Thanks.

Think I'll wait for warmer weather do tackle this job.

 

Seems odd though - the vehicle is barely 3 years old.

Might be the battery. You might want to consider doing it sooner rather than later. You could find yourself stranded with if the corrosion is bad. Might be worth a look to see whats going on under there. It could be that the mechs saw a little and thought ding ding din! Easy money!

 

it may not even require any attention at all.

Or the non profit way, buy a new battery.

 

But I would go with TASB method first.

$59.00. for less than 10 min work and $0.35 materials = easy money.

even if you have to buy the brush ( they actaully have specail brushes @ the auto parts store for this) and a can of spray you will be ahead by $45.

 

and don't forget eye protection when you are cleaning the terminals.

 

 

they guys at Autozone might even fix it for you if you buy the products there.

Wow, $59? Yeah, that's a quick and easy fix just about anyone can do themselves. I'd splurge for the stuff at the auto store, tho. Only $5(?)-ish for some...

put some baking soda on the terminals, let it sit for a few minutes, wash it off and then scrub/brush.  The alkalinity of the baking soda will help offset the acidity of the battery acid.

 

use dielectric grease on the terminals once cleaned.

So how much corrosion is acceptable?

How do I know if there's too much?

rubber gloves
wire brush
vaseline
pliers.

Same supplies you need for a weekend with the Muleman :lol:

Unhook the terminals scrub off all the crud, vasaline them up and rehook up the terminals.

A good mechanic shop should do this for free with other service.

none is acceptable :lol:

 

if there is any there it should be cleaned.  Acid is not good on the loose and there is a reason it is doing it, if it is.  A battery will usually do this if it's getting too hot.  Most common reason in a car is if the alternator is overcharging or your engine just runs hot.  Some engines just run hotter than others.  There are battery blankets for car batteries that will help against engine heat if that is the issue.

 

Clean it and check it every so often to see if it does it again.

The 2 terminals will have a white or sometimes yellow cakey buildup.

Dont touch it without gloves and wash your hands good afterward.

Even if i have no build up my shop does this every couple years.

Good information to have - thanx.

 

Interesting, as I've driven beater cars forever and don't remember ever having this problem.

This is the first new car I've ever owned and :dunno: .

I see you already possess that information.

 

Personally once you have the final bill from the dealership, I would inquire as to why on a 3 year old vehicle they were not providing this service on a complimentary basis.

My favorite new TV wilderness survival dude Mick Dodge in the latest episode he just help a Brit lady with her car stalled out because of corrosion, he used a rock to tap off the corrosion.

That's a fine idea!

It's in there every 5,000 miles.

Be sure to check that you actually have a good ground connection from the negative battery terminal cable to the vehicle frame. Poor ground connections cause any dirt/crud/moisture on the battery case to act as part of the ground circuit, and muck up the battery terminals.

and mucked up terminals can cause the alt to run more, creating heat in the battery, which increases the corrosion

If I could do something over again it would be subbing out drama class for auto mechanics in high school. It pretty much guaranteed me reliant on a man for the rest of my life. Not satisfied with that. 

 

Seany baby, could you do me a solid and come up with a 10 point assessment plan for my daughter in automobile upkeep before she gets her license? Make it 20 and I'll be sure to tip. :smile:

It's pretty much my first go to when I'm stuck. Board provides the lube or the traction depending on the circumstance.
