Etdlahq Memorial Bar - your shelter from forum crashes

Definitely dog person here, even if my avatar is currently a cat. Dogs are fun, cute, friendly, sweet, cuddly, strong, affectionate, g- *trails off*

That didn't help my position at work. I still have 1.5 hrs to go, and I just want to go home. :(

Congrats on the good interview and good luck with it!
 
My wireless router died yesterday. I had a hell of a time getting a new one because the majority come with built in modems. I don't need a modem, just a router but I can pay $80+ extra to get something I don't need. It took three shops but I finally found it.

And BTW, I'm a dog person too.
 
I have both again - they are both different.

Edit:Above applies to both of the last 2 comments.

I have a Dog, a Cat and a Cable modem and a Wireless router
 
I have a Cable modem and a Wireless router, but I don't need a Cable modem and a Wireless router/modem combo. Especially if it doubles the cost.
 
My landlord is doing something with our modem (or our neighbours???) so he's disconnecting ours for tonight. I'm not sure why ours is going down, but I'm sure he does.

But still 30 mins of work, and this is terribly... I don't know. I'm just bored and tired, and the work

Well, I got distracted with something, and nearly 15 mins have passed. But now it's down to reading the web for semi-related stuff. And here of course.

I should've asked a question here, as it's related to work. Has anyone had to jump start their car recently? I keep seeing that you're not supposed to attach the negative clamp to the negative terminal of the battery. Has anyone had any problem doing this, as I believe most people do it. It's supposedly closing the circuit which could cause a spark, which could lead to an explosion of the battery.
Any experiences/knowledge?

You don't need to attach the negative cable to the negative terminal for the battery you're jumping, no. I've never fried a battery by doing so, but the only required part is positive to positive(bad battery), positive to positive(good battery), negative to negative(good battery), negative to something metal/safe on the bad battery's car. Then you remove them in the opposite order.

This is correct. You will also want to check the voltage on the batteries. Most are 12V but some can be 24V and you do not want to connect a 12V to a 24V.

Make sure you do the last negative to a grounded piece of metal on the car. Generally an unpainted piece of metal will do.

Once everything is connected, start the car with the good battery and let it run for about 5 minutes. Then try to start the car with the dead battery. Once started, you can remove the cables in the reverse order.

You should keep dead battery car going for about 15 minutes to charge the battery.
 
Thanks, but not my question. I ask because everywhere I looked said DON'T put the last cable on the battery, although everyone I know does. I've looked at enough to know how you're meant to do it. My question is why not, and what are the chances of causing a spark near the battery which in turn, may have a 'chance' at exploding. What are the chances? Is it a rare thing, or is it basically impossible unless you've got a terribly old battery?

Odds? I know not. Essentially, the issue is the battery leaks Hydrogen in some smallish amounts. Spark hits Hydrogen and ignites the battery, battery explodes and sprays acid and plastic shrapnel. By grounding the last negative away from the battery, the spark is less likely to hit the hydrogen. This is also why you ground on non painted metal.
 
ARGH, I know that. :D Escept for grounding on non-painted metal. I did read that it should be on non-painted metal, but just assumed it grounded 'easier' or something.

I'll state my challenge exactly.

Everywhere says: Do NOT attach the final negative to the negative terminal of the dead battery. Instead, use a part of the engine away from moving parts, fuel lines, etc. Just stick it on part of the engine.
Now, I had to write a procedural document (legally binding) for work, about using a Jump Pack, and jumper leads. When I put to my boss that everywhere was saying "Do NOT" he was saying that's what he's done, and I was saying that's what everyone I know does.

Now, the challenge lies here. If I put something where I have read "DO NOT", as "you can" or "may", and something occurs, well... I don't really care that that's how my boss has always done it, and that's how everyone I know does it. All the written evidence, including Owner's Manual, says "Do NOT".
My boss wants me to put "Do".

I'm asking how likely, or has anyone heard of, or known someone, or experienced, or XYZ, a spark around the battery caused by doing what the evidence says Do NOT (but most people do anyway,) or had an explosion from the battery of this.

As said, I'm putting it in a legal document, and considering the evidence (no documented evidence, but just advice from experts who know more than I do in this field) says "Do NOT", but my boss says "Do", I have reservations. If there's a 0.00000001% chance, and it happens, that'll be a company document with my name on it. :)

[Obviously, I'm not going to say "Do" with this, but I've never heard of it happening, so I'm wondering if anyone has. Especially from kestegsssss who work with electricity and know more than I do. Although he's not an autoelectrician, but he's close enough. :)

Sorry for misunderstanding then. A quick google search doesn't net me any stats but I found a couple accounts of the battery blowing up on someone within the first minute or two of browsing.

Wish I could help more, but I'm sleepy.
 
I should've explained why I was looking into it, but I did try to word my question properly. :)
I didn't have time to google it at the end of the day, as I got a little busy, and thought I wouldn't have internet tonight, so didn't think I could look it up anytime soon. Thanks though!

The issue as far as I know, is not that connecting to the negative will cause sparks (it will cause sparks if you connect to a good ground as well). It is the fact that the negative terminal is located directly above the battery (where you potentially have hydrogen gas). Hydrogen gas has a LEL (lower explosive limit) of 4% (volume h2/volume air). This means you need more than 4% hydrogen in the air to cause an explosure, this is relatively unlikely, but still a non-zero chance.
 
Zombie strippers is on the TV late this evening. Looks like a must see for lovers of bad movies, and I must say I love bad movies!
 
I've made batteries go boom, you do not want batteries going boom close to you.
The chance is low but there still is a chance.
