HP Laptop Battery Test- Tool, Effect Multimeter

Even though laptop batteries are made to have a longer lifespan, they cannot last forever. The battery capacity changes over a period of time. One of the major symptoms of a dying battery is when the charge is lost quickly. Generally, a good one should last several hours before it dies.  If it stays less than an hour after full charge, then the cells are getting weak. As a result, you have to know the condition. The test tool allows you to learn the status of your laptop's battery in seconds. Let us look at Hp- test tool and effect multimeter.

HP Laptop Battery Testing Tool

HP comes with its own diagnostic tool that allows you to check hardware components and detect any failures. Search for HP hardware diagnostics on your computer and select power to check on your battery status. Alternatively, you can purchase a tool that will provide detailed information. Let us look at how to select the best testing tool. 

How to Select a Right Testing Tool

Safety

You have to consider potential hazards when taking measurements. Before using any electrical tool, you should always check the user's operating process, limits, and safety precautions.

Price

Testing tools are available at a wide range of prices. This depends on brand and features. Highly-priced ones tend to be accurate and last longer compared to lower-priced models.

Versatility

Basic testing tools have features like measuring voltages, capacitance, resistance, AC, and DC current.  Conversely, others provide tests such as battery test, diode test, transistor test, and continuity test and special functions like an analog bar graph, auto range, true RMS, analog bar graph, and RS- 232 PC interface.

Display Counts

Display counts or the resolution of a meter is the small part of the scale. A higher display count is better than a lower one.

HP Laptop Battery Test Failed

If you get an error code such as MCW6JF-7H091D-MFPV6K-C0B403, then you need to replace your battery. Error code 601 means that your battery can only store a maximum of 25% of its original capacity. Ensure that the battery is installed properly; otherwise, the test will fail.  Note the number of your battery and search online for an original HP part.  Searching using a number will help you get a compatible battery. Most people end up buying batteries that cannot even fit their laptops. 

You can also search for Certified HP suppliers in your country. Walk in the shop with your laptop if you are afraid of buying at the wrong time. Before leaving the shop, it is highly advisable to make a quick battery test to make sure that it will serve its purpose. There are many fake products out there; the only way to find out is by running a battery diagnostics check tool on your computer or using a millimeter. 

If you are buying from Amazon, search for the seller with the most reviews. Make sure the specs match your laptop. The tests fail only if your battery needs replacement. If the laptop does not detect the battery, then it probably needs replacing too. Some technicians can repair the laptop batteries by replacing the faulty 16650 batteries. Please do not try this by yourself if you are not qualified. Laptop batteries are highly dangerous and flammable if not handled with care.  Batteries do not last forever, but if you take good care of them, then they will serve you for a long time. Testing it periodically is useful because you will easily find when it needs replacement.  

How to Test HP Laptop Battery With a Multimeter

A multimeter is a test tool for measuring at least two electrical values. Generally, it can measure current, voltage, or resistance. 

Follow the steps below:

●Charge the laptop battery to full

●Turn off the laptop and remove the battery. Then search for voltage rating on the battery; you will use it to compare with the multimeter reading. Most computers have voltage ranging from 9.6V, 10.8V, 11.1V, 14.4V, 14.8V, lower or higher ratings.

●Find the connector that the battery interfaces with the laptop.

●Turn on the multimeter and set it to measure direct current volt on anything near 20 volts. To find the Voltage setting, look for the letter "V." On the other hand, direct current voltage settings are displayed by straight lines near "V," which is different from the alternating current on wavy lines.

●Put one prong of the multimeter in the outer slot found at the end of the battery connector.

●Check the reading on the multimeter. A healthy one will show a close value to the printed value on the battery.

●After 60-80% discharge,  measure the voltage in order to get the difference of the full charge value. A depleted battery cannot measure a value close to 0V.

Ways to Extend HP Lifespan 

The following tips will help you to prolong the natural life of your cell:

●Avoid extreme temperatures

Cold and hot temperatures strain the cell, thus can shorten lifespan. Ensure you charge in a favorable environment.

●Charge  and discharge fully

It is recommended to charge or discharge it completely.

●Remove the battery

You can remove it if you are going to plug it for a long time.

●Avoid fast charging

Charging quickly causes stress.  The slower the charge, the better. You should avoid fast charging

●Calibrate the laptop battery

Calibration is a process of changing battery stats that display wrong battery time. This can cause the device to shut down before the mentioned time. For this reason, it causes disturbance to the user. To solve this problem, you have to calibrate occasionally.

Final Thoughts

Laptop batteries can fail after some years.  This will depend on factors like quality and computing behavior. Hp batteries are not different from others. Also, they wear out faster compared to other laptop's components.  Therefore, you have to learn if it is dying. However, you have to know prior to replacement. The tips mentioned above will help you to test. Moreover,  it is easy to check your battery's health to avoid unwanted surprises. Lastly, if you find out the cell has died, ensure you dispose of it in a proper way. They are very toxic thus should not be put in the trash. You can get instructions from the HP recycling center.
