Motors Why do car batteries have the worst timing?

Can't do that in a car with a catalytic converter, it pushes fuel out of the exhaust and into the cat and poisons the cat, which then means the car fails emissions next test-time.

 

Ours died in an open car park in Abu Dhabi - 50C air temp, no shade (it had been sat for a LONG time). We walked to the nearest restaurant and got the manager to phone his cousin (it's always a cousin) which ended up with a guy on a moped with a new battery between his feet. Just sat by a fountain drinking tea and eating sandwiches, by far the best breakdown ever

In england the RAC guy helping the guy NEXT to me with a flat battery outright refused to let me just quickly jump my car (we'd left our lights on in the station car park on a foggy morning )

 

I would check the connections to the battery too. For whatever reason this has been my issue with nearly every battery that has just gone 'klunk' when trying to turn over. The stupid clamps on the terminals are the worst for this.

Mine had done this very thing with a new battery, so I clipped off the old clamp and bought a replacement one that was real thick and will never move. Then applied some anti-corrosive spray to keep that weird powder crap from forming.

 

I've got a sweet jump start box for the somewhat regular occasions when this happens to me. They are well worth having. My car's 24V, so the chances of someone passing by who can give me a jump start is slim.

If you use your car regularly then you may have a charging problem BTW.

 

thats bogus. ive popped the clutch on many an emissioned vehicle and never hurt the cat.

it takes a LOT of over fueling for quite a long time to build up the heat required to melt a cat. and if your talking about carbon build up then any slight amount of soot deposited on the substrate will be blown out the tailpipe as soon as the engine fires.

cat converters are actually fairly hearty.

to the OP...maybe you should carry a set of jumper cables. they dont need charged, and they are cheaper than a jumper box (although the expensive heavy gauge ones are NICE). although that all goes out the window if you break down somewhere where you cant bum some juice off of a good samaritan.

 

if it happens again after jumping/charging it check your alternator.

 

Tryed it last night 11pm and worked fine

and have used it this morning got £1.50 for a single in my pocket again but im sure it should be fine im just worried if it might do it again at a worse time im working from 5-9pm tonight so if it stops then its going to mean calling someone out quick before some arse wipe takes my plate and gives me a ticket (even though i work there!) i might get my dad to check it over see if theres anything obvious

Mind you we did have pretty bad weather the other day water up to the wheel arch of a double decker pretty sure it would'nt have come near the battery but i guess it could have been that

And my sister got a lift from me tuesday she finished early so she sat in the car with the radio on im sure that would'nt effect it that bad again i guess its a possibility will see what happens

 

I smell much bull sh*t in this post, much bull indeed.

the small amount of fuel vapour during a clutch popping session wouldn't effect the cat in anyway mate.

Your not pushing the car with it in gear and clutch in mate, turn key to position 2, select 2nd gear, push and pop the clutch up once a decent speed is built up.

I've bumped a car on my own, volvo at that! You just need the minerals to do it.
