yes it is necessary..
it operates a battery,mostly a 9 volt battery
My 2005 SLK350 has a +ve connector under the bonnet. Its under a red plastic enclosure and has a hinged cover on it. Just access this connector and clip on your charger. You shouldn't need to access the battery.
Its not known
First clip on the dead battery +(positive), Second clip on Good battery +This is the same color cable if you have color cables or just make sure that what you connect it is of the same polarity positive with positive and negative with ground (body of dead battery vehicle), Third clip on Good battery - (negative), and Fourth clip the last cable to the body on the vehicle with the dead battery. Give like 20 sec and try it if nothing make sure that your ground cable is making good contact and try again, also is good to have radio, a/c, etc off when jump starting.
Yes you do need a battery because the paper clip is usually used for an alternative for a wire and the paper clip is what the electricity travels through, so yes you do need a battery.
Connect the positive clip of the battery charger to the positive terminal on the battery. Connect the negative clip of the battery charger to the negative terminal on the battery. Select the charge rate you desire either 2,4, or 6 amp. The newer battery chargers will let you know when it is fully charged.
You have to pull a plastic clip/lever up until it pops out. That will free your battery. You may have to rock it by pushing down and pulling up to loosen the clip.
provides emf and direction of flow of current
Take a Energizer, Duracell, etc. battery (the bigger the bulb the bigger the battery) and a paper clip. Bend up the paper clip to a pretty straight line, and attach one end to the end of the lightbulb. Attach the other end to one end of the battery, and POOF! Light! If the bulb doesn't come on try attaching the paper clip to the other end of the battery. If it STILL doesn't work, get a bigger battery.
a paper clip is not neccessary but is an easy way of holding paper and other materials together
It is very easy to replace the battery on a 1994 BMW 318i. The battery can be found in the trunk on the right hand side of the car. All you need to do is to use a screwdriver to take the plastic clip holding the battery in place off. After the clip is removed, take the battery out and then replace with a new one.
No, it is not safe to do so. Clip them only when they have adult feathers and only when necessary.
