Exploding battery.

I went out for a quick hunt today. I packed the Ace, my Explorer and my Pocket Probe. as I raced out the door, I chucked my mobile and spare 9 volt battery into the same pocket. I was trying to reach the $800 mark with the Ace today (from when I bought it; it's been a slow year this year) I was less than a dollar away. After which, I intended to use the Explorer for a bit, but as it isn't as good as the Ace for pinpointing, I'd packed the Pocket Probe and spare battery to assist the Explorer at target location.
After about half an hour, I felt and heard a BANG which caused me to spin around a see if somebody had thrown a throw down at me. I couldn't see anybody so continued to hunt. Another 10 minutes later, I heard a similar explosion, but this time I spotted some smoke coming from my pants pocket. Whoops. After a quick inspection, I pulled out the 9 volt battery that had it's bottom blown away, and top bulging. Inside were what looked like 6 AAA batteries!
No harm was done and my mobile phone still works. My best guess , is that the battery earthed out on the phone.
The moral to the story. DON'T CARRY BATTERIES IN YOUR POCKET!!

P.S. Found 5 cents. Still 65 cents short of the target and won't have much time to detect over the next 3 weeks, after which the family will take a holiday the Gold Coast (a target rich environment!).
 
Mick,
A 9volt battery is nothing more than 6 AAAA batteries connected in series. Then they install them in the 9 volt case. Sorry about your pants exploding!!
 
I had a battery explode on one of our cordless phones at home. Luckily it wasn't in use when it happened.

Too bad we couldn't program phones at the other end to explode....especially when someone calls to sell you a vacuum cleaner during supper time.

I went to Naval Nuclear Power school and everbody always carried a spare battery for their calculators during exams. If your calculator stopped functioning you were SOL and there were no windows in the school so solar was not an option. No speaking or leaving your seat was allowed during exams. Get the picture? Anyway during one exam this sailor leapt from his seat and ran from the room screaming. We all figured he just cracked up. What had happened was a nickel in pocket shorted across the leads of a 9v battery and burned his leg. So bad, in fact it left a nasty nickel size scar on his leg which he frequently displayed. You had to be there.

I saw this happen with a drill battery at work in a pouch full of screws. It's no joke, you could get a nasty burn. I carry my extra batteries in a small pouch in baggies on my pouch belt.
 
Yeah. Especially those Indian call centres that ring you back repeatably at 3 A.M ! and those automated calling systems that do the same thing, only with nobody on the other end of the phone to chew out when they keep ringing you. Should be an international law against these actions.

Back in high school sitting in class I had a handful of wood strike-anywhere matches in my back pocket. During a test, I must have moved just right to cause one to strike off. My south end was hot and puffin smoke as the bunch went off.
I didn't finish the test and experienced detention with a burned bun and a charred hole in the back of my pants. Afterwards I had dad laughing on one side while mom finger flicked the ear on the other side - and spoke a few choice words.:rant:
 
And after all these years, there is still a bit of a burn scar mark there.
I didn't; know till then that I could brake-dance impromptu for the class.
 
Several years ago when the large horn-rimmed glasses were in style, I was trying to jump start a forklift at work on a cold morning. When I attached the cables, one of the caps popped out with a bang and hit me exactly between the eyes on the bridge of my glasses. It broke them completely in half at the bridge. It put a big knot between my eyes. Looked like someone hit me with their fist. I was lucky the whole battery didn't explode. I've seen it happen. Needless to say I have changed the way i jump start anything now.

You're a lucky man Al. I've heard of a few horror stories of people recharging car type batteries with the caps still on.One of those people died when the battery exploded.

Yeah the best way is to use the body as a ground instead of the negative post on the battery. Saw a battery blow up in a guy's face one time. Wasn't purty.

Al[/quote]I would also invest in a pair of safety glasses.

Mick Evans.[/quote]You need to leave the caps on so the hydrogen gas condenses back into the battery. You need to make sure the gas is cleared out before you pull the cables.
 
The battery thing happened way back in the early sixties. Hardly anyone used safety glasses then. Later in life I lost almost all the vision in my right eye due to gluacoma. So for many years now I do very little without safely glasses. I do a lot of wood working so don't want to damage the only eye I have left. I'm trying to convince my wife to use them when she mows and "weedeats". Not having much luck. "Off the rack" sunglasses is about all she will wear.

It's so easy to lose your sight from just something simple like debris being thrown up into your eyes from a trimmer, it just ain't worth the risk! I totally agree with you.
