Help battery acid!!!

Recommended Posts

I was installing my BHAF today and discovered that one of my batteries had blown up or something (a big piece of the top had broke loose and I could look right inside) and there seemed to be acid splattered all over under the hood:bang::bang: Any suggestions what would be the best course of action to clean this up? I did go to the car wash and washed it off good with soap then rinsed real good.

Lots of fresh water quick! Then even more fresh water... But I would replace both batteries and double check the charging system and the cables for problems. Check for error codes because maybe the battery temp sensor is bad... Guessin'

Baking soda and water will nuetralize any acid. Look at the battery tray, in the center is about a 1" circle.

Battery temp sensor?? This is a new one to me.

It located under the driver side battery. It senses the battery temp and regulates the voltage to prevent gassing of the battery which in turns dries them out. The old school regulators use to sense the under hood temp and under charge the batteries which caused them to fail early. Now with the new technology the battery life is extended greatly because it always gets a full charge (if driven long enough) and done in such a manner to keep the electrolyte from boiling out and drying out a cell.

Side Note...

My house is totally battery powered... The inverter has the same battery temp sensor mounted on a battery to control the charge rate and keep the batteries from getting gassy on normal charge. Give you a clue the 8 6 Volt batteries are 15 years old and still holding awesome charge and the light NEVER go out at my place! :thumbsup:

That little circle with a spring under it on the drivers side is a battery heat sensor?

I popped the hood to look at this sensor but I got so many positive battery cables and wires and things that it's almost fragile to touch lol. I have 3 big cables going into one connector and a bunch of other wires. Actually let me just take a picture so you can laugh at it. They make these really big bolts and nuts where the bolt has a big slot down the middle and it's all copper and just smashes all the wires together. Can't remember what it's called and heaven forbid I take all that tape off :lmao2:

Ah, one of these, split bolt connector. Posted Image

I need to make a copper block with set screws for each cable and wire. Hmm. Maybe I will make one tomorrow.

NICE! I see these all over the place at the powerplant I work at. Mostly for grounds and bonding straps, first time I've seen them in an automotive application.

Yeah they work good. I need to do something different though. I'd like to move all my batteries to the toolbox but I seem to lose a lot of cranking amps when I do that. Have to come up with a new configuration of doing it that will keep the amps up. I have gained and lost many cranking amps simply by rearranging the negatives. Try and put them all over the block instead of the chassis and it cranks over much faster. There are 3 bolts on the engine mounting brackets that bolt the mount to the block and there is a 4th bolt above the hypotenuse of the mount (mounts shaped like a triangle) which is on both sides of the block, I have big negative cables on both bolts and it makes it crank very fast. I think the one positive going to the starter is my only limiting factor now.

Don't worry. As long as you hit that wire with the connecting hook at precisely 88mph the instant the lightning strikes the tower... everything will be fine.

I have a very bad habit of turning things philosophical..but I can't make any sense of that no matter how many different ways I look at it :lol3: I have a few ideas of what your talking about but I am not sure.

the movie...back to the future!! watch out mcfly!

any way...isx, what gauge wire did you use to wire up the extra batteries? what kind terminal clams did you use? i am about to change the factory clamps...but the wire is so thick, im not sure i can find clamps to except it....just looking to see what others have done

10-4 on the baking soda and water will neutralize battery acid. Also makes the best battery terminal cleaner I have ever found. We have been using it in our shops for decades. If you can, try to use warm to hot water. Hood Latch

Oh, never saw that movie lol. I just used ones like these. You can loosen the bolts all the way and fit just about anything in there. I got all my extra wire from a long welding lead we had. Posted Image

those style clamps are what i used on my ranger and honda.... but the "pit" where the wire fits looks like it is to small. i think my cable on the dodge might be 0gauge or even 00....i guess i need to do some shopping :( has anyone ever take those factory terminal clamps off the wire? it looks like the wire is pressed into the clamp. the negative on my drivers side is so jacked it won't get tight around the post http://forum.mopar1973man.com/attachment.php?attachmentid=457

Get a very thin file (1/8" thick), take the negative terminal off and loosen the bolt or take the bolt out, pry the middle out a little bit and file it down so you can tighten it down more.. The two faces of the terminal that meet (that I'm pointing too) are what you have to file down, you will have to take the bolt out and get pliers on either side to pull it apart and get just enough room for the file to get in there, then file it down a little bit.

Geez... Get some engine oil on those cables... Even mine don't have rust or corrosion on them at all... Look like you been getting carried away with terminal cleaner and over tightening. so if you remove the terminal and clean it will and coat it will engine oil and re-assemble but just snug the terminal you'll never worry about it again. Just remember if you wash the engine bay to recoat the terminals with engine oil.

that is a trick i never knew...i had never touched those clamps until i put those batteries in...some times you inherit someone else's mess. but then i'm still shaking the motto: "if it ain't broke, don't fix it". preventative maintenance is a much better motto. the negative in that pic is loose enough to wiggle off the post...and i can't get it much tighter because i can't get a good bite on the nut.

Take the negative terminal off so you can get a good bite with vise grips or anything and just replace the bolt and nuts. I swear battery's have a way of softening the metal in those nuts which is why they strip so easily. Hmm, I have a crazy idea that would fix all those grip problems for good. Have to try it when I get home.What in the hell is going on with the positive terminal? You got nuts on both ends :lol3:
