The question of how long a particular battery will last, depends on how often it is used. On average, a P511 will give its user about 115 hours of continuous use.
It actually depends on your usage as the more the battery is used , the quicker it discharges
The battery on a cordless SDS drill lasts for between 1.5 to 3 amp hours. You can purchase a small supply of batteries so that you can switch them out and recharge the used up ones while working on your construction project.
According to Energizer, they claim that their rechargeable AA batteries will hold their charge for up to 1 year. How long a battery lasts is also dependant on how much it is used.
A battery will last 3-9 hours based upon the number of cells it has. The more cells the longer the battery charge will hold. The battery charge will also depreciate over time. It will last for a shorter and decreasing amount of time as it is used more often.
A mobile battery can be used at anytime unless it is damaged. The longer you store the battery, the shorter it will last. All batteries get ruined, even if not used. This has to do with the chemicals inside the battery. It's suggested you use it while you last. You have a good 3-4 years or more until the battery starts to die.
A 5600mAh battery can last anywhere from a few minutes to several hours depending on the device it is used in. Typically most cell phones can last for many days with limited usage.
That completely depends on how much current is used by the circuit or device that's connected to the battery. For example, if there is no circuit or device connected to the battery, and no current is used, then the battery lasts for quite a long time. But if you lay a screwdriver across the battery terminals and create great balls of fire, then the charge on the battery may only last for 1/2 second.
"Last" can be a verb when used to mean to continue to exist or to endure. For example, "How long will this battery last?"
