The rate of self discharge for any battery depends on the storage temperature. At higher temperatures, batteries discharge at a higher rate and the reverse for lower temperatures. Ni-MH batteries self discharge at about 1 percent per day at normal room temperature and conditions ? or 30% of their charge. Li-Ion batteries have a lower self discharge rate.

The hardware configuration of your notebook. High-end notebooks (with high-tech features) require a lot of power to run. A system using a DVD-ROM, a large LCD screen and other features shorten the charge time considerably. Usage. When the system has to perform a task, power is required. Spinning the CPU fan, CD/DVD drive, transferring data from the hard drive and even typing on the keyboard affect the charge time.

The battery will take between two and four hours to fully charge (depending on usage, type of battery, and the current charge percentage. NOTE: It will take longer to fully charge the battery if the notebook is in use. The AC adapter must also supply current to the system (in addition to charging the battery).

Run time on a single charge/recharge could vary as much as 10%, so from about 75 to 100 minutes.

The fast-charge time for iPod is up to one hour. This charges the iPod battery to 80% capacity. The full-charge time is up to three hours.

The time required to charge a battery depends on the battery type, the capacity of the battery, and the type of charger being used. A higher mAh battery will take longer to charge than a lower mAh battery. In general, it will take 3-4 hours to "rapid charge" a battery to the 80% level, and an additional 8 hours to “slow or trickle” charge a battery to the 100% level. A good approach is to charge your battery overnight for about 12 hours. (more about chargers)
