cell phone lithium battery How phone battery is checked using multimeter in mobile repairing course.

In this article, we are trying to understand how to use a multimeter in the field of maintenance, because many people face a lot of problems when using a multimeter.Students are facing problems with cell phone batteries!Battery exhaustion is one of the most common problems associated with mobile phones.This is caused by battery consumption due to various functions, applications, functions, etc.
The professionals check these batteries so that they know the exact problem.Here, in this article, I will tell you how to check the cell phone battery using a multimeter in the mobile repair course.What is a multi-table?Before jumping directly to this process, it is important to know what a multimeter is.
This is a test tool for diagnosing electrical connections in electrical devices such as mobile phones, laptops, etc.Previously, the analog multimeter was used in the mobile maintenance center.They are reading the reading with a needle gauge.
However, now-a-A digital multimeter with an LCD display is usually used.Using the Digital Multimeter, students learn the following in the mobile repair course: Test the voltage test to accurately measure the continuity test of the grounding resistance, its functions such as voltmeter, ammeter and ohmmeter.It's a handheld device, so there's no problem bringing it from place to place.
It has two lines, one is a red probe () and the other is black (-) Probe with metal tip.Both must be connected to their respective outlets.Test preparation: students studying mobile repair courses in Bangalore do not use the device directly, but first check the work with the following tips: brush the two tips together.
If you hear a beep, the device works fine.Test equipment is turned off at all times.If it already has a voltage, an inaccurate reading will be received.
Steps to check the cell phone battery using a multimeter: Step 1: first, switch the phone-The battery is dead.Step 2: check the battery voltage given on the battery label.The voltage of most batteries is 3.7V/3.8V.Step 3: Now, students place the battery so that they can easily see its terminals.
Step 4: The digital multimeter is set on the DC setting indicated by the DCV, or only V is set.This is a straight line with 3 points below.There are several settings in the DCV, such as 2mv, 20 V, 1000 V.
Always keep the number higher than the battery voltage.The curved line (ACV or V) indicates the AC voltage, but do not use it as a setting because the mobile battery operates at a DC voltage.Step 5: The Red probe is in contact with the terminal of the battery, again, the Black probe is in contact-Terminals of the battery.
(You will see the sign on the front and back sides of the battery ).Step 6: The probe will not be removed unless a stable reading is received on the multimeter screen.If read more than 3.The battery is 70 v (3.7 V) then a battery full of electricity.If it's less than it's 3.Then the battery needs to be charged.This is the way to check if the mobile battery is charging.
Also, if there is 0 v, it is obvious that the battery runs out.Sometimes, even if the reading remains the same after charging, the battery fails.At the Mobile repair Academy in Bangalore, students are trained on how to use a variety of test and repair tools, where it is essential to read the multimeter!.
