That depends on the current drawn from it. Standard D cells are rated between about 10,000 mAH to 15,000 mAH. Therefore a load drawing 100 mA from a D cell should give a lifetime of somewhere between 100 hours to 150 hours. More current shorter life, less current longer life.
No set answer to that, it depends on the power consumption of whatever they're connected to.
200 minutes
60 hours and 35 minutes
Depends on the quality of the battery, the number of batteries, and the amperage drawn by the bulb or LED.
a car battery last for about 3-5 years
No. The sizes of the batteries give indication as to how much current they can produce at that voltage.Another Answer:There is no A-cell battery. There are AA batteries packaged in a D shell. If you avoid those, a normal D-cell will deliver a lot more energy than an AA-cell, so connected to the same device/load it will last longer.
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.
D cell battery
No the battery is built in but should last a long time.
