Battery Pic and question

what does this indicate? i have since cleaned it all off.

 

Low charge

 

That is really bad corrosion! Clean with baking soda and water.

 

Clean it good. Make sure anything it touches is cleaned up as well. Since the corrosion is on the positive side, it most likely is due to overcharging.

 

thanks...i am taking it in first of april and have the pic in my phone. cleaned it, will see if it comes back by then.

 

How old is your truck? How many miles on it?

Use and age can contribute to "why did this happen?"

 

16 10K miles one thing comes to mind, i drive with ECT on all the time, engine RPM's are higher?

 

Only 10k miles on your 16? Nice. Idk what really causes it. One guy says over charging which idk about the stock system recharging at a higher rate. I've drained my battery a couple times on accident and i had some green on there. Maybe the connector and post are two different metals, or have 2 dissimilar metals causing a reaction..

 

10K miles..can't go far on maui.

 

Could that be from salt in the air?

 

heres a silly idea, maybe the battery is just bad?

 

that is a silly idea

being in Hawaii you are more likely to get corrosion due to heavy salt content in the air. Just check the battery more frequently and clean it, not a big deal.

 

I’ve had battery corrosion on new vehicles before. For a dollar or two
I always install rings on new batteries and have had no more problems.

 

Had an Accord with that problem. I noticed the terminal was actually a little loose in the case and you could wiggle it. Eventually required a clamp replacement. Regular cleaning and a monthly shot of this

kept it clean until it was replaced. I still use the spray on my Tacoma as prevention.

 

2nd on the terminal protector. I just used some of that on a friends battery and also used some battery cleaner spray that I’ve had for many years to clean it up prior to using the protector spray. It seems to wipe off easier than baking soda with an old rag. No water necessary and less worries about splashing on your paint.

 

Once you have corrosion like that it will keep coming back unless you use something like the green and red rings.

 

I’d just check your CCAs and cold voltage on that battery. Mine looked similar to yours and it was dying on me - replaced it with something heavier duty that will last longer than the year I had mine before it started to degrade.

 

clean it and rub grease gun grease on the connector and terminal.

 

I had a bunch of corrosion show up on my negative terminal all of a sudden. Not sure what that is indicative of. Cleaned it off and watching to see if it reappears.

 

Check the battery water level. Fill with distilled water up to the bottom of the plastic level indicator legs. You will know it when you see it; once you pull the caps off the battery. Warning sulfuric acid, do not splash.
