How to Choose Good Mobile Phone Battery - Look Here!

We Know, Although battery models vary heavily from phone to phone, there are some basic criteria which hold true for most phones with interchangeable batteries. The point is, do you choose the best battery for yourself? Next, we will provide the best ways to test cell phone battery. 

1. Check Appearance

The most direct way is to check the appearance. A good cell phone battery features no oil stains, stains, scratches, points on the concave and convex surfaces and no cracks in the input and output points. In addition, another important area that is often overlooked is battery contact to ensure that the battery terminal is not oxidizing. Of course, a qualified alternative battery needs to be compared with OEM through a size test.

2. Test Function

At this stage, a cell phone battery tester and a conversion universal instrument are needed. The specifications like battery resistance, voltage, charge and battery capacity, need to be confirmed. In spite of this, the sampling test and the complete test are applied according to the actual situation.

• Resistance and voltage test

Switch the cell phone tester to the static parameter setting mode, and then check the value of the display.

• Charging test

Select the charging function and set the correct parameters. Then start charging and see if it works properly.

• Capacity test

- First, the current capacity and energy capacity of the battery needs to be checked on the label.

- Then switch to the battery capacity test and set the correct parameters.

- Then completely discharge the battery, then charge it, discharge fully, move back and forth like this.

- After many charging and discharging cycles, the discharge current capacity and discharge energy capacity gradually balance. According to the data recorded in the operation, the average discharge current capacity and the discharge energy capacity value are calculated. This is the return standard to the cell capacity of the cell phone: Deviation: 10%

• Drop test

It is also one of the acceptable reliability grades of cell phone batteries. First the battery is fully charged, and 30 minutes later, let it fall in a natural way to the 18mm 22mm board at a height of 1 meters. Check the battery failure or have any damage appearance.

• Charging cycle

Last but not least, some computer software can play a role in helping us check the full battery charging cycle, such as iTools (relative to iPhone's battery that is not removable). Connect the iTools into the battery owner and check the full charge cycle.

Battery Activation Tips:

Some customers reported that the battery did not recharge. For some new lithium batteries, they only need to be activated before the function reaches the best performance. Here are 5 suggestions for your reference.

1. Charge and match the charger for a period of time. Remember to insert the data cable first and then install the battery.

2. Use the battery activator board.

3. Use the DC power supply.

4. Use the universal charger.
