When calculating the life of a battery it will be necessary to know the number of charge cycles that can be performed until the battery does not begin to lose its capacity.
Depending on the type of battery these charging cycles can vary, the most common being the mobile batteries, manufactured Li-Ion or Li-Po, which have a duration of between 300 and 500 charging cycles according to model and manufacturer.
Once thisE limit we will notice how the battery loses duration of operation, arriving to lose up to 25% of its capacity of load.
At this point it will be necessary to evaluate a battery change.
It should be noted that usage and charging habits can significantly affect battery life. For example, factors such as heat, charge the battery several times a day without it is almost exhausted, etc. Will be affectedits duration.
Therefore, to get the most out of the battery we must know when a full charge cycle is performed, and try to avoid misuse of charge, to increase its useful life.
A charging cycle is considered when the battery has been discharged or its 100% charge has been used.
The manufacturers advise that the charge is never made below the 58% battery, since the battery voltage would not fall so lowTo, so you could end up winning up to 4000 charge cycles.
Tips to increase the life of a battery.

• Avoid extreme heat or cold or very long applications of the device.
• Charge the battery as often as you can.
• Fully discharge the battery from time to time.
• Do not let the battery run out completely before charging.

Below is a table with theDifferent voltages (V), charge cycles (C) and battery percentage (B).

Li-Ion or Lithium batteries are one of the most common batteries used today.
We can find this type of batteries in mobile phones, wireless headphones, SAIS, smart watches, cars etc.

Lithium is a very light metal capable of generating ions easily so it is ideal for the manufacture of batteries.

Unlike other types of batteries are a bit more expensive, but acThey are much smaller and lighter, capable of doubling the duration of a Ni-Cd.

Thanks to their composition can be manufactured in different ways, adapting to the device where they should be located, as well as its low memory effect makes them ideal for any type of device.

Summing up their positive points:

• Easy to find
• Many different sizes and shapes
• Small size

It is called an rpm (revolution per minute) to the unit that is used to express the angular velocity. It is the number of complete turns a body gives around an axis.
