A very important term to know when talking about mobile device batteries is the “charging” or “discharge” test. These are typically done by having you use your phone for an amount of time (usually called a usage period) and then comparing how much power it has left to see if it can be recharged.
This differs from a true “capacity” test, which looks at how many times a cell can be charged and retain its charge. True capacity tests usually require expensive equipment that only a few companies have.

Voltage tests

A very important test for any new battery is to determine its voltage limit. This is done by battery testing at one-half of its capacity and then seeing how long you can use it before it stops holding a charge.
The longer you can use the battery, the higher its voltage limit will be! It is prudent to do this test initially as batteries lose their hold over time due to usage.

Current tests

Many companies have their own set of standards for ...
... how they test new cell phone batteries. Some use statistical methods to determine if there is a difference in battery performance between the two products. Others compare the overall capacity of a battery over time or measure voltage levels at different points during discharge to get an average value.
Some even put the product into a charger and watch it charge! This is called “charge-rate testing” because it determines how fast a battery can re-juice after being drained.
All of these strategies are used to assess whether one brand’s cells are more effective than another’s at maintaining power, but none consider potential safety differences. That could be due to improper balancing, something that some manufacturers do not check before shipping, or potentially harmful additives like cobalt, lithium, or manganese that differ among brands.

Temperature tests

The next test we will do is to determine how well your battery performs at its highest temperature. This can be done by doing an extremely high heat discharge, using the battery, or both!
To perform this test, you need to fully understand what kind of cell chemistry your battery has. Different chemistries require different-sized thermal protection layers to work properly.
Never leave your device unattended during these tests as possible burning and explosions are very real possibilities!

Capacity tests

The most common way to test battery capacity is by doing what they call charge-discharge cycles. For this test, you need a source of power for the discharge (take away) cycle and a time marker when the battery is fully charged.
There are two main reasons to determine a battery’s capacity. First, we want to know how much energy it can hold so that we can predict how long it will last. Second, because some batteries lose their strength over time, we want to make sure our current pack of batteries will still work properly with your device.

Electrolyte tests

An important part of any new battery’s life is how it de-gels or loses its charge over time. Batteries will lose some of their capacity to hold a charge as they use up chemical components, and these chemicals weaken and eventually disappear (leak out) from the cell.
This is called electrolysis, which happens when current flows through the battery, causing oxidation and reduction reactions that produce gas and water. The gases are what cause problems in some cells – if too much builds up, the pressure can lead to the battery and cell testing exploding or rupturing.
If you look at almost any smartphone today, you will find that most batteries have an insertion tool that users insert into the device. This is to test the quality of the battery. These tools usually consist of very fine needles that pierce the protective layer coating the positive electrode, creating a small hole.
If there is no resistance to the needle going in, then the material is not sufficiently thick and strong to prevent electrons from flowing easily between the liquid inside the cell and the surface of the negative electrode.
