Batteries are one of the weak links in laptop computers. We all rely on our laptops for a variety of things and knowing how to test laptop battery can be crucial if important docs are on your laptop. Batteries also tend to wear out faster than other laptop components.Once the performance gets bad enough, you'll need to replace the battery. It's fairly easy to test your battery's charge and health, and by doing so you can help avoid unwanted surprises.

 

 

Checking Battery Charge in Windows

Step 1

Click on the Windows button to open the Start Menu.

 

Step 2

Look for a search bar that says "Search programs and files"at the bottom of the Start Menu.

 

Step 3

Type "Windows Mobility Center" into the search field. When the results come up, click on "Windows Mobility Center" in the Programs section at the top of the results. Windows Mobility Center has various indicators to show whether your laptop is mobile.

 

Look for the "Battery Status"indicator. This shows you what percentage of battery power you have remaining. If you typically keep your laptop plugged in, it should read close to 100 percent.

Checking Battery Charge with a Multimeter

Step 1

Fully charge your laptop battery.

 

Step 2

Turn off your computer and remove the battery. Look for a voltage rating printed on the battery. This will be the number to compare with your multimeter reading. Many laptops have voltages of 9.6V, 10.8V, 11.1V, 14.4V or 14.8V. Some have lower or higher ratings.

 

Step 3

Look for the connector where the battery interfaces with the computer. It will be near the center of the side of the battery that faces the computer when plugged in. Roughly an inch in length, it should resemble a series of at least five very narrow, identical slots that looks a little bit like your laptop’s exhaust fan grating, except smaller. The outermost of these slots will be the positive and negative terminals of the battery.

 

Step 4

Turn on your multimeter and set it to measure direct current voltage on the 20-volt scale (or anything close to 20 volts). Voltage settings are indicated by the letter "V" and direct current voltage settings are indicated by straight lines near the V, as opposed to wavy lines for alternating current.

 

Step 5

Insert one prong of your multimeter into the outermost slot on one end of the battery connector. Insert the other prong of your multimeter into the other outermost slot on the connector. It doesn't matter if you match your positives and negatives. If you get them backward, it will just change the sign of the voltage, not the actual number, and the number is what's important. Make sure each prong is touching bare, exposed metal.

 

Step 6

Observe the reading on your multimeter. A fully charged, healthy laptop battery will measure very close to the printed value on the battery.

 

Try measuring your battery's voltage after a 60- to 80-percent discharge, to get a comparison against the full charge value. A depleted laptop battery won't measure anything close to 0V. There will still be several volts in it. What happens is that, once the battery drops below a certain voltage, your computer automatically shuts down. This is because if the voltage drops too low the battery will become damaged. Protective circuitry in the battery will then make it impossible for you to use a dead battery.

Checking Battery Overall Health

Step 1

Fully charge your laptop battery.

 

Step 2

Turn on your computer, unplug it from the power outlet and run on the battery only.

 

Get a sense of how fast the battery is draining. A healthy battery should last roughly as many hours as it says on the package. An unhealthy battery will drain much faster. Don't drain the battery all the way for this test, but about halfway instead. Once your battery drains too fast for you to get practical use out of it, it's time to get a new one.

Active, pre-charge, constant current and constant voltage are the stages of charging mode. The initial charging mode depends on the battery voltage, so active and pre-charge don't happen to every batteries.

Testing time is 30 seconds and the purpose is to check both the charging and discharging performances.

 The battery capacity value in the battery management chip will different from the actual capacity after a battery goes through many recycling cycles. It will affect the use of the battery when the difference reaches a certain degree. Capacity correction is to deep discharge a battery and then fully charge, which will correct the capacity value in the battery management chip.

Charge firstly, and then discharge to 50% capacity.Discharge firstly, and then charge to 50% capacity.

When we use a notebook, we may encounter such a situation, that is, the battery of the notebook cannot be charged, which is really a headache.

So what if the laptop battery doesn't charge?

Let's take a look at the repair method of notebook battery.

laptop not charging

 

 

When the battery of your favorite notebook does not charge:

 

With the use time getting longer, notebooks will have various problems. There is a phenomenon that the notebook can be used for a long time when it is disconnected from the power supply, but the battery can't be charged due to the long use time, leading to the notebook computer’s inability of being used without the power supply finally.

Why is this situation happening and how to solve it?

Cause Analysis:

1. Software Problems

Generally speaking, many computer brands, such as Dell, Lenovo, Sony, etc., will equip their notebooks with power management software during the production. If a certain "battery protection mode" is enabled, the power management software will prohibit the battery from charging and discharging after detecting that the user uses AC power, so as to prolong the service life of the battery.

Therefore, if you find that your notebook is not charged, you can first enter the relevant power management software, turn off the battery protection mode or tick off the charging prohibition option. If there is nothing wrong with the hardware, the battery can be charged later.

2. Hardware Problems

There are hardware problems of the battery itself. Generally speaking, we can judge by restarting the computer and reseating the battery. If the battery still can't be charged, you may want to install some hardware detection applications to get the approximate reference information of battery loss.

If a battery hardware failure can be determined, you’ll be recommended do not open it by yourself or try to repair it, because there will be certain risks. In this way, it is better to find someone professional to repair it.

 

 

 

Safe Repair Method of Notebook Battery Charging Failure:

1. Enter the bios when the computer starts, the option "start battery calibration" is usually found in the power project, then start it;

2. Generally speaking, the user will be reminded to connect the power adapter for full charging firstly, and then a text will be displayed to prompt the user to disconnect the AC power supply. The Windows7 Ultimate system will continuously discharge the notebook until the power is completely exhausted, and then the notebook will automatically shut down. At this time, we can connect the power adapter for charging, but don't turn it on. After the charging indicator light goes out, the whole process will be completed.

Note: The bios battery repair process may take 5 hours, so be sure to operate it when you don't need to use your notebook. If you can't improve the battery status after these attempts, it is probably that this battery is broken, so you can send it for repair or buy a new original battery.

The above is the solution that the notebook battery can't be charged. We just need to enter the bios and choose the option of using battery to repair this problem. If it can't be repaired, the last step is to replace the battery.

There have been a lot of complaints by notebook owners finding that the battery life of their newly purchased notebooks was deteriorating rapidly. Battery life would drop 35% after just a couple of months of usage. The problem is not the battery per se, but rather a firmware coding issue with the notebook that causes it to grossly under estimate actual battery life left and shut down prematurely. In other words, the notebook thinks there is 0 – 5% battery life left when in actual fact there might be up to 30% — or an hour’s worth of life. This may also be a problem for other notebook users outside of the battery and is therefore worth anyone reading to understand what causes a notebook to shut down when it thinks battery life has become critical.

 

Misuse of notebook battery

 Misunderstanding 1: 

The notebook lithium battery should be fully charged when used. In fact, excessive charging and discharging of lithium batteries will rapidly reduce the activity of the batteries, so users need not deliberately charge them to 100% during use.

 

Misunderstanding 2: 

As long as it is turned off, it can be put on the bed even if it is powered off. In fact, it is easy to cause the battery to overheat and even cause a fire. Therefore, we should try to avoid placing computers on sofas, beds and other places that are not easy to dissipate heat.

 

Misunderstanding 3: 

The battery of notebook computer has never been removed. In fact, the problem of overcharge does not exist for a well-designed lithium battery, because the lithium battery has a protective circuit.

 

Misunderstanding 4: 

Even if the notebook is fully charged, it is still connected to the power supply and continues to be used. In fact, in addition to reducing the battery life, the simultaneous use of alternating current and battery will also cause overheating of the machine and easily damage other components.

 

Misunderstanding 5: 

The battery should be fully charged or completely discharged for storage. In fact, it is not correct to activate the notebook lithium battery regularly, whether it is fully charged or fully discharged. The correct method is to discharge it by about 30~40%.

Mathematical Calculations of Battery Life and Wear

 

This is where I can also prove there is a direct correlation between wear % and battery life. For this let's assume the critical alarm is turned on, just like everyone has it on.

 

Given

 

Battery Capacity is 77whr (B)

Average consumption is 25whr (C)

Brand new battery has 0% wear (W)

This will differ from laptop to laptop, but this is the general settings for my V1JP.

 

Battery life = (((B x W) – B) / C)

BL = (((77 x 0) – 77) / 25)

BL = 77/25

BL = 3 hours

 

This shows if you have a 77wh battery, and if your consumption rate is on average 25whr, and your wear % is 0, then your battery life is 3 hours, this matches my original battery life test in my review.

 

Battery life = (((B x W) – B) / C)

BL = (((77 x 35%) – 77) / 25)

BL = ((27 – 77) / 25)

BL = (50/25)

BL = 2 hours

 

This shows if you have a 77wh battery, and your consumption rate is an average of 25whr, and you rwear is 35%, then your battery life is 2 hours, this also matches the results, and you can see it on the Up Time on CoolMon2.

 

This also shows how battery wear does affect your battery life. You can even calculate another interesting factor.

 

Wear battery life = 100% charge = 3 hours of battery life with 25whr consumption on a 77whr battery.

Wear battery life = 3 hours x 60 minutes = 180 minutes on 100% charge with 25whr consumption.

Wear battery life = 180 minutes /100% charge = 1.8

 

This value 1.8, means how much battery life in terms of minutes you lose per 1% of wear. So if your wear percentage is 35%, then multiply 35 x 1.8 = 63 minutes, which is exactly how many minutes you will lose to your wear %. My laptop shows this exactly with 35% battery wear. I hope everyone understands and follows this!

 

Test Settings

 

P4G Mode: Quiet Office

Screen Brightness: 2/16

Light Task: Typing this article and some browsing

WIFI On

 

 

Use these settings to test  battery life to keep up with the consistency of what happened before and to calculate what happened today.

Discharge Rate Comparison

 

V1JP Review: Discharge averaged 25 W

School: Discharge averaged 23-24 W

Battery Article: Discharge averaged 25-26 W (fist 2 hours)

Battery Article: Discharge averaged 28W (for the remaining time due to increased fan RPM and blinking battery LED)

 

The cells in laptop batteries degrade over time, and it is totally normal for old laptop batteries to hold charge less than an hour. Current laptops can achieve up to 10 hours of standard usage because of the software that comes with the perk of a new laptop. Henceforth, upgrading your laptop hardware will significantly improve your laptop battery life.
