My mums battery went dead yesterday so today she decided to charge it back up.. left her to it only to get a phone call later to say that its blown up, now at this point i was thinking wtf she on about..

anyways gets home and found this in my mums Audi

 

oh dear.... a bit fcuk`ed

 

What she do? connect the charger up the wrong way? (- to +) etc?

 

dont think so, i checked it befoure i went out and was all fine she said she took the charger off tried to start it and it went bang! got back and found loads of bits scatterd across the drive way

 

Fook!

 

slightest spark can set the gasses off o a charging or freshly charged battery, weve done it twice pmsl


the last time we was trying to test a starter so had it sat on the battery whilst it was charging withj couple bits wire to the starter

i know duurrrr lol

fook me did she go bang, my ears were ringing for hours

the acids rots the fook outa ya clothes etc too, i take it ya have removed the batery ad washed the car down?

 

did you take the vent caps off?

 

yes mate first thing i did when i got back was remove the battery after takin a pic lol.

left mum to wash the car down while i went and got a new battery for her

 

what vent caps?

 

a battery which ISNT sealed should have the caps on the top u use to fill it up removed as when chargin gases build up (pressure) and thats whats prob made it explode!

 

the covers on the top of the battery they are usually 6 screw caps or 1 big rectangle cap. These need to be removed before charging or the gasses build up inside and as you now know explode!

 

knew i forgot to check summin

 

Has it fooked the paint work too? Lucky it didnt catch on fire mate!!!

 

nope paint work is fine unlike the battery

 

Benn its all your fault

 

V lucky escape then mate, take it as a lesson learnt

 

Use water with bicarb-soda in to rinse clothes and paint work. BTW the gas is hydrogen like in the old airships, makes a proper bang.

 

 

you have whitnessed the power of hydrogen gas

Well at least everyone's ok.

 

Tony, how its my fault lol, i mearly checked that she had the charger connected right

 

 

it wuold be your fault if you didnt take the vent caps
of mate, that was very luckyit didnt do anymore

a member of this site had his 3 door cossie go up in flames as
he didnt take the vent caps of the battery.

 

now know y mi dad takes the caps off lol

 

fook never knew you had to take the caps off, dont say nuthin about that on the battery
thought they had built in pressure release on modern ones surely.

 

apparently not mate

 

lesson learned: befoure charging battery make sure caps are off..

 

ya also have to leave the batt for a hour or so after chargin otherwise they can go bang is ya use it straight away


so rember children, go to halfords say batt is fooked and let one of them monkeys take the risk, collec the following day to either a brand new bat foc or a freshly charged bat thats ready for ya car


oh and NO battery in my halfords has ever been charged with the vent removed, infact a guy once spilled batt acid on his hand and actualkly asked me what he should do as its stinging his hand

 

Had that happen to me on an LDV when I was in iraq , prob didn't like the 60 degree+ heat , me and the lad who were in it fookin shit ourselves, thought we were being attacked, should have heard the bang it went with , sat on the taxi-way just after we finished servicing an aircraft

 

 

dont know how true this is but ive been told if your battery dont
hold charge tip the acid out in to a try re fill with battery acid
and charge it for 12 hours and it will last for at least another
2 years, my mate told me this and says he has done it aswell.



remember take the bloody vent tops of if it's not a sealed battery

 

Never tried that but it could give a little life to a fucked battery.

Most failures are due to sulphation of the lead plates. As the plates decay they are less effective and parts of the plate may actually fall and settle in the bottom. What can happen is the cell is shorted by lead pieces, so tipping them out may help a little but the battery will not be rejuvenated.
