Are you ever surprised when your computer, or electronic project, suddenly shuts down because the battery died?
If so, then you might like the idea of a battery gauge. It establishes communication between the battery and the user by determining the amount of charge remaining in the battery. This allows you to know when the battery is low so that you will be able to save your work and charge your battery. That's if it's rechargeable.
Same as the other types of batteries, Li-battery is used to store and release energy at the desired time.
This type of battery is a member of the rechargeable battery family composed of a chemical component known as lithium. This battery can last 2-3 times longer than an alkaline battery, which is the most popular battery type.
Li-batteries are mostly used in wireless systems because of their performance under extreme temperature.
Some of the parameters we need to know about the battery are as follows:
Voltage:
We say the battery is full when the voltage is 4.2. While we consider the battery empty when it reads below 3.2V. Do not let the battery exceed the maximum voltage value since it might explode. Discharging a battery below the minimum voltage value might cause damage to it and might be hard to recharge it again.
Capacity:
Batteries are rated according to current capacity. Current capacity determines how fast the battery would discharge in certain conditions and it’s expressed as mili ampere-hours (mAh).
Q = I x t , where Q is capacity, I is current and t is time.
C-rate:
Specifies the current used to charge and discharge a battery. For example, 1000mAh battery would provide 1000mA current for one hour if the rate is 1C. The same battery discharging at 0.5C rate would provide 500mA for two hours.
Temperature:
Within a temperature range of 5 to 45 degrees C, a Li-battery shows good charging performance. If the temperature is not within the range, it would degrade the performance of the battery or results in slower charging time
