Do you mean activate the battery when it won't work?
you can take it to the place you bought it
no
yes.
Repeated discharging of the battery will destroy it. Connecting the cables in reverse will destroy the battery. An alternator that is overcharging will also destroy the battery. Vibration and or dropping the battery will do it no good. Lastly is age. Over time the battery will cease to function.
Pretty much everything. It provides the spark for the spark plugs, the power for all electrical and electronic components, etc. The alternator doesn't take over for the battery once the car is started - it simply keeps the battery charged.
Something is discharging the battery when it is not running. Have the electrical system checked.
As long as the battery is functional you can continue to jump it. However, know that every time you run a car battery down you shorten its life. A battery that is designed to be run completely down and then recharged is called a deep cycle battery. Automobile batteries are not deep cycle batteries. Discharging them completely causes damage to the battery itself.
If you mean if a regular household hot glue gun can be run off a car battery, then - no. the voltage is too low for it to heat up enough to activate the glue properly.
because you need a new battery for your car
Parasitic voltage drain. Are you leaving something like an inverter plugged in? If you installed a new car stereo or amp for example and connected to a power source that is "hot" all the time, whatever is on that line will drain the battery all the time.
Over and over as long as the donor car is running. How many times is hard to tell.
A car battery's function is to store electrical energy for your vehicle. When you start the car the stored energy in the battery turns your car over and once your car starts the alternater will power everything and recharge the battery.
Cranking the car or starting the car in cold weather can wear out a car battery. You can also wear out the battery by turning the starter over without fuel in the tank.
