Perfect 27Wh / 3Cell DELL 90TT9 60NGW Battery

Today, this focus on the notebook battery discharge curve, hoping to help customers.
In fact a laptop battery can be used to established how long depends on many many factors. Machine settings, the running programs, operating practices, environmental temperature and DELL 90TT9 Battery temperature, the machine will affect the actual use with a battery time.
In "to develop good habits," a little introduction to this article, interested users can look at. Although the use of time depends on many factors, but the laptop battery discharge or have a certain regularity.
  If the discharge current is almost constant, then DELL 60NGW Battery capacity will decrease linearly over time, to a certain level of capacity will be steep drop, then continue for a relatively short period of time.
 
Shown above, test machine Using DELL 60NGW Battery two different discharge the battery at full load conditions of the curve.

There are the more popular chips M37516 + 4494, this program primitive, M37516 is a common MCU, in fact with the PIC, AVR MCU can be replaced so many, it is characterized by a A / D, PWM, I2C interfaces. Write programs in the M37516, achieving BQ2060 features a naturally can not for Dell Laptop. Of course, writing programs to achieve with the M37516 is certainly not easy to use dedicated chips.
