It should hold it's charge for at least 3 months or possibly longer.
The battery in my 2006 lasted 6 years before starting giving my fits.
With no charging the battery could last a few minutes. There is a large amount of power needed to move a car forward. Starting would shorten the time.
a car battery last for about 3-5 years
I recently had a car battery replaced. They last for maybe 5 to 6 years or so but always remember to never run aircondisioning without starting your engine (if you run the aircondisioning on the battery it reduces its life) In addition, running the battery down will shorten it's life.
As long as the battery is kept charged then it should last 3-5 years.
a panasonic triple a battery last about 4 hours nonstop.
about a year.
8hrs
Forever.
No the battery is built in but should last a long time.
A Sanyo phone battery last just about as long as any other battery. Most batteries are manufactured by just a few different manufacturers, and then rebranded.
If you divide the 5000 mAh by the current used (in mA), you will get the number of hours the battery will last.
