The most important spec in any laptop includes a battery life that make it last sufficient amount of period. While all the other specs like processor, storage, or RAM count as very essential, a laptop is probably nothing without a battery. Having a solid battery life in a laptop makes it a competitive device. It all depends on the overall capacity of battery power engine and how good manufacturer has equipped the gaming laptop with.
It is sometimes hard to keep up with the batteries. A number of factors depend on your current battery condition. You can be careless and not entirely taking care of when and how you should charge your laptop. Moreover, using the laptop battery more than it is required to be can also cause a lot of damages. In all cases, you must always know how to maintain the battery of a laptop and test it for precautionary measures.
To test the laptop battery with multimeter, you can just follow simple steps and procedure. The must-have thing here is to have a digital multimeter which is definitely easier.
Step 1:
Make sure that you charge your laptop battery to 100%. It should be fully charged.
Step 2:
Turn off your laptop and then take out your battery. Your laptop’s battery charger must have the voltage that is written or printed over on its back. Check the number which should be amongst the following current ratings.
- 6V
- 8V
- 1V
- 4V
- 8V
The voltage ratings may be higher or lower depending on your laptop.
Step 3:
Now you have to check the battery connector and find where it is. Mostly, the place where battery is attached with the laptop which is the center of the device. The major portion in the dotted or vertical lining shape is there where you can connect the battery from the laptop. The narrow, and identical gaps that also appear like the gaming laptop fans but are smaller in size are there. The positive and negative terminal is indicated on the inside of the slots that you can identify.
Step 4:
It’s time to turn on your multimeter and put it on a 20-voltage current setting. The voltage should be around 20 and not much more or less. If you are not still aware, the settings of voltage are indicated by the “V” sign. The straight lines indicate the direct voltage of the current that are near V. The wavy lines, on the other end, indicate that you have alternate current.
Step 5:
The one point of the multimeter needs to be connected to the outermost connector of the battery inside the laptop. Similarly, the other point of the multimeter will be attached to the other end of the battery. You do not have to take care of connecting positives with the positives or negatives with the negatives. You can still get the number out of the opposite connection rating. Every prong connected on both sides should touch the bare side of the metal.
Step 6:
The simple thing to do now is reading the multimeter voltage. Now the reading must match the voltage that is printed on the battery or can be somewhat close.
Step 7:
Just after you have checked the actual voltage when your laptop is fully charged, now check it when the battery is discharged up to 70 or 80%. A laptop that is exhausted, its battery wont measure anywhere near 0V. You will have several volts left in a depleted laptop. If the voltage drops down under a certain amount of voltage, then the laptop is automatically going to shut down. The protective circuitry of the battery would not allow the laptop to run if the voltage is lower or below.
Bottom Line
Checking your current laptop battery using multimeter is not any rocket science. You can also additionally test the battery using the Windows and also determine the overall health. It is important to keep your laptop battery in check so you can make your device run longer with a healthy overall system performance.
