Not very good advice if you have a modern car, most manufacturers state that their cars should not be bump started!!!!

Absolutely. I understand it can cause a lot of damage to the catalytic converter

Utter rubbish. What some of them do state is that they shouldn't be jump started as in started using jump leads from another vehicle.

As a <cough> Transport Manager you should know this, especially as trucks like the ERF EC11's were reknown for not being able to be started with jump leads as it blew all the main fuses for the engine management.

Every car battery I have ever bought has been supplied fully charged.

You must have been very lucky to get one that's just been delivered from the manufacturer every time then.

Most car batteries will only start a car a few times when fully charged,

You may want to go do some rudimentary maths. You'll find out that a fully charged battery can keep a starter motor turning over for quite a while. As my car starts within a few turns, it'll start my car without being recharged many dozens of times. In fact, I've run a car for nearly a week commuting to work and back covering 300 miles with a duff alternator on a single battery charge.

Oh, and then there's the Top Gear feature from a few years ago where they raced a mini, golf and some jap thing round a racetrack using nothing but starter motors to propel the cars which also proves you wrong.

Well lucky on a number of occasions then clearly.

Sadly until I invested in a battery conditioner my little 2 seat sports car got through a battery per year.

Bump starting is not recommended by manufacturers as unburnt fuel can enter the cat causing damage.

Can't see any issue with jump starting though.

You want to try Jump Stating a Hummer, for a start no conventional vehicle (or jump start kit) is powerful enough to do it (even using a second Hummer), they have a special HUMMER booster pack for them.

Most, if not all cars I have owned or used since at least the late 90's have advised against bump starting, they give advisories when using a jump start, normally about making sure all electrics are turned off and to make sure the negative goes to the engine mount or other similar good earthing point. I think you might want to go and check and then feel free to come back and apologise.

And as for the commercials, trying to bump start a 7 ton tractor unit is not really practical is it!!! And if you have to work for a company where that is common practice then I am glad I have never had to work for them, cant see the rest of their maintenance procedures being that robust!!! Quite apart form the fact that we are talking about chalk and cheese, I mentioned my job as a way of qualifying that I have purchased many batteries in the past, all of them having arrived charged, I never mentioned my role when talking about bump starting a car!!!

So when you want to try and berate someone then please try and separate the facts that you are relying on and put them in the correct contexts, it makes things so much easier in the long run.
