FAQs

Ask question

When should I know it’s time to replace the laptop battery?

 

-  Your laptop battery could wear out over time and with regular use. Over a longer duration of time, your battery performance will deteriorate with increasing use and it will lead to your battery draining much faster than normal. You will also notice a significant drop in run time. You may typically notice a decrease in runtime before 18 months. When the runtime is insufficient for your needs, we advise purchasing a new laptop battery. You can either opt for an original battery or a compatible battery from a reliable brand like Lapgrade from www.mylaptopspares.com

-  When the laptop is connected to a power source via the AC adapter, the battery in the laptop charges. Depending on the laptop, the charging time varies. Ideally, the battery should charge between a range of 60%- 80% capacity in approximately an hour and reach full capacity in about two hours while the laptop is turned off. Once the battery is fully charged, you should remove the adapter till battery is discharged to a level of 10%-20%

- Always buy from original brand sources or a reliable seller.

-Match whether or not the number of cells and charge capacity is the same between the original one that you have and the one that you are buying.

-Check the battery info view which is easily available online on the company website completely free of cost.

-Check if the warranty is given directly from the original brand.

- Your battery will drain fast.

- You will face uncertain power failure.

- Your windows will report to you about battery issues.

- You will notice a rise in your laptop temperature.

- Please read on the top of your existing battery, where the battery part no. is normally mentioned. In case there is difficulty in finding the same, please drop an email to the customer support of My Laptop Spares at contactus@mylaptopspares.com giving the complete make, model no. of your laptop, and picture of your existing battery. We will assist you further.

Step 1: The first step is to turn off your computer and unplug it from the power outlet. Remove any external devices connected to the computer, such as USB flash drives or external hard drives.

 Step 2: Next, remove all screws holding the casing of your laptop together by getting under each side of the laptop with a small flathead screwdriver and gently prying out each screw with your fingers. Once all screws are removed, carefully lift up one end of the laptop at once to separate it from its casing completely.

 Step 3: The next step is to slide out any cables connected to your motherboard (the part inside a laptop that connects all internal components), including those for the Wi-Fi antenna, Bluetooth radio, and other networking components.

Once you've removed these cables completely from their sockets on the motherboard, follow them out of open ports on the underside of your laptop so they're free from interference when you put in new ones later on.

 

- A compatible battery is the best option if the one which came along with your laptop is not working properly anymore. Compatible batteries are always an affordable and safe option for without a doubt and you can make them much safer by following a few precautions while using them. Compatible batteries are better than the original ones because they have an equal battery life just like the original ones. One of our suggestions for such a compatible battery is here.

 

- Please refer to our return & cancellation policy.

 

-If you have any doubt with respect to compatibility, we suggest you check the compatibility with us before ordering. Our team provides guided assurance on compatibility.

Laptop Battery Trouble Shooting Guide

Troubleshooting Methods:

Before you decide to purchase a new battery, follow these quick and easy troubleshooting steps to make sure you truly need a replacement:

  • Remove the battery and try to install it multiple times to ensure the battery is properly placed.
  • Could be due to conductive material damage to the laptop motherboard and battery anode and cathode contact position, you can try and check it with your original battery.
  • Look whether the battery drive is in normal condition, if not, download the corresponding driver software to update.
  • Take out the battery and press the power button for about 15 seconds to consume the internal residual power without connecting the power cord, and then reinstall the battery. Try this several times.

3 Ways to Replace your Laptop Battery

For Internal batteries:
  • The first step to replacing the battery in your laptop is finding it.
  • To do this, you’ll need to remove the cover on your laptop carefully and look through the various compartments inside.
  • Remove the old battery by removing the screws in the bottom of your laptop.
  • Now place the old battery on top of your new one so that they connect together properly and fit snugly into their sockets!
  • Once you’ve removed the old battery, you should be able to install a new one without any problems.
For external batteries:
  • Unplug or disconnect the power cable.
  • Turn your laptop such that the bottom is facing upwards.
  • Look for the battery latch of your laptop. (some of the latches are shown in the image)
  • To remove the battery, slide the latch switch to the opposite side.
  • The battery will either pop out on its own or you can just pull the battery out gently.

How to identify internal and external batteries?

The internal battery is usually located underneath the laptop’s keyboard, while the external battery is usually located in the laptop’s power adapter.

To identify the internal battery, look for a small, rectangular battery pack underneath the keyboard. The internal battery is usually silver or black in color.

To identify the external battery, just turn your laptop and look for a battery latch. Slide the latch to the opposite side. The battery will either pop out on its own or you can just pull the battery out gently.

Steps to follow with your New Battery

  • As soon as you receive your new battery, discharge the battery to 5% and not 0%, then charge to 95%, and continue the process 3-4 times with your new battery.
  • The key here is to perform a full discharge and charge every other month to extend the battery life.
  • Make sure you don’t connect the adapter for a longer duration while using it to avoid any possible damage to the battery.
  • Avoid artificial shocks, disassembly, crush or puncture. Do not dispose of it in fire or water.
