Seven years
You should get a couple years out of it, but it really depends on you. If you constantly run it low and then recharge it, that's deep cycling, and will reduce battery life substantially.
Impossible to say. A decent battery should last at least 3 years. A great battery may last 5 or more years. Remember every time you run the battery down, you are cutting it's life short. Keep the battery clean and fully charged and it will last a long time.
Average life is from 3-5 years. If you run the battery down you shorten it's life.
No the battery is built in but should last a long time.
The battery in my 2006 lasted 6 years before starting giving my fits.
As long as the battery is kept charged then it should last 3-5 years.
Batteries have no set time for replacement. They can last from 2 to 7 years. Change it at the first sign that it is weak or will not start the engine.
A dell inspiron 700m battery should last for a few years. Most of the time, they die because of hardware problems or spilling. But if they are maintained they will last for a long time.
30 seconds
The Rechargeable Lithium-Ion Battery Pack should last about six to ten hours of use.
The battery is advertised at having a life of up to 6 hours. Depending upon the usage depend upon he battery to last for 4 hours.
No set answer to that. It depends on the capacity of the battery and the power consumption of what it's connected to.
