I need a new battery,,,,,,,,,,,,,,

I guess that you have never seen explosions of a battery being jumped, with the hood open, or a battery in a shop with the doors open connected to a battery charger exploding. (In the latter case, the idiot charging it was smoking, and that's what ignited the gas.)

It happens, not all the time, but sometimes. The odds might be 0.1% of it happening, but if it happens to you and you are killed, you will be 100% dead, not 0.1%.
 
No, I completely agree with you Joe that they can explode when being jumped. But afaik batteries only produce that quantity of gas during large current draws. Under regular operating conditions, being charged as it runs, the levels of gas would be very low.

And during a jump, the battery is open to the air, so the vent hose wouldn't be making a difference. That being said, I'd pay the extra for a vented. Safety specifications aren't usually for day-to-day life, they're for when something goes wrong. They wouldn't require venting if there wasn't a good reason, even if a problem is unlikely to occur.

I'd still be most concerned with corrosion within the electrical box. I don't know how well those are sealed, but given how computerized these cars are, poor connections can lead to all sorts of problems.

I agree with your corrosion concerns, however, I still think that the safety concerns are bigger. Yes, under normal circumstances, there is no explosion danger, vented or not. It is abnormal circumstances that I would worry about. The two quickest examples are:
A fault in the alternator causes massive overcharging of the battery.
A wreck causes a short circuit at the main battery connections.

I also disagree about a vent not making a difference during jump starting. With the vent, the hydrogen will be under/behind the battery and unlikely to be a problem during a jump. Without it, hydrogen may be around the battery and may explode. (Yes, this is no different than most cars with a battery under the hood.)

Anyway, I think that we both agree that the battery in the trunk needs to be correctly vented to the outside.
 
I have had a battery explode as soon as the ignition key was turned in my truck. stop trying to justify not fixing something correctly. when the alternator charges the battery, hydrogen gas is produced. it has to go somewhere. this takes place when the engine is running, dont cut corners. the young guys on this site have no idea how to fix cars the correct way.
 
Stereotyping now, eh? One's age does not dictate the level of knowledge. To group me ( a guy younger than you) into a category of having "no idea how to fix a car the correct way" is dense, and very ignorant on your part.

Either you practice what you preach ("common sense"), or step the f*ck off your soap box.

It's just proof that with age comes experience, but not always wisdom.

I know some younger than me that are very good with cars, and some that aren't. I also know some older than me that are good with cars, and some that are bad. I don't see any pattern at all that says older = better.

Ditto. 1991; Wife at the mall in Sears' parking lot; she turns the key and BOOM! Battery blows up. I opened the hood when I got there and the whole top of the battery had blown off! I have never seen that before or since!
 
What happens when you connect + to - and - to + when jumping someones battery, will it explodes too?

Either battery might explode, but usually they don't. Very often, much of the electronics in the car being jumped are damaged/destroyed this way.
 
lol. No pics/ no damage ;)


Ok I was scared of you saying it could explode cause it happened to me. Lately my battery has been dying about once to twice a week since I'm at school all day and enter and leave my car a lot. Well about a month ago I needed to get jumped and finally abot 20 girls later, cause thats who only passed by in the parking lot, this nice girl agreed to jump me. It was late and half the girls prob thought I was lying and wanted to rape them or something. Well she pulled up with the camry, it was so dirty in the bay area and the battry terminal had no color to them. I was trying to look for the sign, cause some cars have them reversed, but couldn't find it, Started scratching away at the dirt and fond some color on the terminal plugs. Well the colors were flipped!!!! cause when I connected the jumper cables, the battery smoked up and my girlfriend tried starting the car before I could get them off, I jumped back.lol.scary.It made the cable connectors that orange red hot color. Scared the S**t out of me. Switched the cable around and started the car. After that a bought myself a little started kit so no more dirty switch batteries. Nothing got damaged but maybe my battery did a little. Just hearing all this barrety exploding got me thinking I could've blown my face off with battery acid all over it. Geez
 
I have observed an exploding battery when it sparked connecting the positive even to the correct terminal. If you get luck and avoid the flying shrapnel you can get covered with sulfuric acid, not a fun thing. To this day I'm very cautious around jumping cars battery's.

Kinda off topic, but still a pretty interesting photo.

The cause was never really found out with this one. It was one of about 10 that were all wired in series and were not overcharged. All were put in the same conditions.

I think it was finally chalked up to being an internal problem from the factory, but still scary stuff...
 
WOW. Thats a nice looking battery, must be a new model
 
same old mentality. rig the wrong battery because I wont spend the money to do the job correctly. How about should I buy a car with a lien and part it out. do the younger guys realize the power steering pump takes Mercon V because it is hydraulic pump just like a transmission?
it's not stereotyping when it is painfully obvious how little some of the members actually have any car experience.
Many of the members are very smart when it comes to cars, but it seems many are not.
Holy S, people need to relax on the sensitivity issues.

good thing we have you around to steer us in the right direction....geeze dude....you drive and fix your car, i'll drive and fix mine.

hmmm....is this jwerner with a new screen name?
 
Guys relax. I told the guy about the battery. His exact words were "I'ts cool. Im not worried about it".
 
I not here to steer anyone, just to point out the redundant mentality of some of the questions. does the dude even understand what a lien is? does the dude understand that a financial institution actually owns the car until it's paid for?
does he realize he could get arrested for possessing a stolen car even if he has a receipt?
I doubt it on all 3 questions.
the original post was about not doing the right thing, putting the wrong battery into the trunk of a car. If that does not bother people, then it is a statement of your character. some of the questions sound like they are coming from a 15 year old, just my observation, not a stereotype.
remember, you are responsible for your behavior.
 
Here is a photo of a Optima Yellow top that shorted out in the trunk of an Lincoln LS:

That may be true, but experience doesn't necessarily have a direct correlation with age. You need to cut the young guys some slack and not lump them all in that "irresponsible punkass kids" category, IMHO. We have plenty of young gearheads and "irresponsible punkass old farts" around here, y'know.
 
I did not use the term punkass, your words.
I dont care how much experience you do or dont have, the intent of the forum is to share information and help anyone that might have questions.
intentionally cutting corners to save money is not cool at the risk of doing something unsafe!!
