NO. BATTERY'S DIE AFTER MONTHS OR YEARS OF USE, IE DISCHARGING AND CHARGING. THE LEAD PLATES INSIDE...THAT WHY BATTERY'S ARE SO HEAVY, GET WORN DOWN AND EVENTUALLY WOLD TAKE OR HOLD A CHARGE AND THEN IT WILL HAVE TO BE REPLACED.

I have never had a problem with jump starting cars.
My procedure is this:
Hook up the positive lead to the dead battery.
Hook up the positive lead to the good battery
Hook up the negative lead to the good battery
Hook up the negative lead to a metal part away from the battery.
Then let the cars sit for a couple of minutes, this will allow the alternator of the running car to charge the dead battery a little.
Then try to start the dead car.
Once started, remove the negative lead that is grounded on the metal of the dead car.
The reason that you don't put the jumpers to both of the battery terminals is when batteries charge they give off hydrogen gas, when you hook or unhook a jumper cable there is a chance that there will be a spark. Hydrogen will explode and possibly the battery will explode if there is enough hydrogen and the spark is close enough. So when you unhook the negative lead you do it away from the charging battery, that is why you use the metal ground for the negative lead.
good luck.

It does not, providing you use the correct technique:
1: The vehicle performing the jump start must be running (engine on) and not in contact with the dead vehicle.
2: Cables in this order: Positive to positive, negative to ground. Yes, ground. An unpainted frame member, a bolt on the engine, free from anything that moves, a clearly signed negative jump start component, ANYTHING but the negative post of the dead battery.
Why? A vehicle's charging system runs between 13.6 and 14.6 Volts normally. Trying to pump that voltage directly in to a 12 Volt battery, ungrounded, will likely give you an acid face bath.
Not pretty.
To unhook, reverse the procedure.

it doesn't hurt the battery ,but i have seen it blow out an alternator,i blew mine out a year ago jumping another truck off,and now i wont give no more jump starts,i haven't seen it hurt any battery's though ,but you know if it will ruin an alternator it can also get a battery,the older the battery is the better chance is that it could mess it up,good luck with it.

Depends on that maufacturer really, but im sure it doesnt hurt any average car battery. Ive never heard or seen any problems jump starting vehicles, but maybei just always did it correctly.

It will not hurt anything unless you do it wrong or the battery is ready to go out.
