Seven years
No the battery is built in but should last a long time.
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.
As long as the battery is kept charged then it should last 3-5 years.
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.
It depends on the load.
5 years is about average. But it could last 7 years or no more than 3 years. Every time you run the battery down that will shorten the life of the battery.
If it is a quality battery it should last 3-5 years. Now if you run the battery down a few times you decrease it's lifespan. There is no way of telling exactly how long a battery will last. I have had them last 6 years and also had a few that lasted less than 2 years. I am replacing the faactory installed battery on my 2004 V6 Tacoma today. It is just over six years old and shows no indication of being bad, I am just being safe.
