 Nothing can put a damper on your laptop experience quite like a faulty battery. From trouble charging to overheating and more, there are a few tell-tale signs to look for when a malfunctioning battery is affecting your laptop’s performance. 

#1 You Have to Charge the Computer Often

One of the most obvious signs it may be time to reassess your laptop battery is if it dies much sooner than it used to. On average, expect a fully charged laptop battery to last six hours (depending on the programs used). But as the laptop battery ages, it doesn’t hold its charge for as long. If your laptop is barely making it past a couple hours, it’s likely a sign the battery needs replacing.

#2 Overheating

All laptops are designed to cool themselves during use and dispel excess heat. If you notice your laptop is hot to the touch, your battery is likely working too hard and unable to cool itself. Your battery is having to work harder to power applications. Often, an excessively hot laptop will also be noisy since the internal fans are working overtime to cool the gadget. This causes your computer to overheat, which can strain your computer. NOTE: Always unplug your laptop and stop use if the machine is overheating to avoid further damage.

#3 Your Laptop Keeps Shutting Down

While the occasional glitch may not always signify battery issues, be sure to make a note of how often your laptop powers down on you. If your Mac or PC powers off unexpectedly, and especially after a recent charge, you can likely assume a faulty battery is the cause. Try charging your laptop again, but if the problem persists your battery may be out of juice permanently. This may be a sign instead that your battery needs to be replaced. A bad battery doesn’t hold charge for very long, and your computer will unexpectedly power off.

#4 Age

While there are many great options for both Mac and PC fans on the market, no laptop is designed to last forever. If you’re experiencing power issues with your device, it may simply be due to its age. Don’t be surprised if you experience power issues. Generally, laptop batteries become problematic after 1-2 years or 300-400 charge cycles. If your laptop is older, your battery has likely been living on borrowed time and is ready to be replaced.

#5 Slow Charge

In addition to issues stemming from charging, it may also be a warning sign if your laptop charges exceptionally slowly. A healthy laptop battery will charge quickly and retain its power when disconnected from the charger. If your laptop is charging at a snail’s pace, or even worse- only charging when connected to the outlet, you may need to replace your laptop battery.

#6 System Report

In addition to performance issues, most laptops are already equipped with technology to check their overall health. For Mac users, expect to receive a battery service warning when service is needed. For Windows users, consider generating a battery report to check your battery’s health. Depending on the messages from your laptop, you can easily determine whether it’s time to replace your laptop battery.

Friendly reminder: If you need to replace the battery of your device, this battery store will be a good choice: www.batteryforpc.co.uk

 It is known to all that almost all batteries are lithium batteries now. When charging, the lithium electronic polymer will produce a small amount of gas when it is discharged, which will cause a slight expansion, that’s normal. Overtime that gas will build up and cause the battery to expand.

Other Causes of Laptop Battery Swelling

1- overcharging.

2- Manufacturing defect, such as no protective plate inside, unreasonable distribution of positive and negative plates, uneven distribution of lye (electrolyte),etc.

3- Exposure to high temperature, the battery will be overheated and deformed.

4- Deep discharge.

5- Damage to the battery, such as damage to the membranes that separate the internal layers of the battery.

6- Natural aging.

7-Using a charger of the wrong voltage rating.

Is my battery swollen?

A variety of problems—some rather subtle, or impossible to ignore—can indicate that the internal battery is swelling, such as the screen not closing properly, a gap between the upper and lower parts of the case(enclosure splitting), a failure to sit perfectly flat, system rocking when placed on an even surface, touchpad or keyboard lifting or not working properly, and keyboard and touchpad might begin to warp or could start protruding. Sometimes it may be accompanied by: overheating, fast-draining battery.

If your system has gone through 500-600 charge-discharge cycles, you should replace the battery on priority basis, some users who wait till the battery backup comes down to 5 minutes and don’t consider to replace the laptop battery then the battery can swell.

With an iPhone or iPad, a swollen battery is usually obvious because it starts to warp the case and can even crack the screen—it all depends on where the swelling takes place and what part of the device gives way first.

In some cases, a swollen battery may also leak, resulting in a very pungent strong smell of metal. This can easily damage other components to the point where it may be unable to be used.

If you smell burning or metal, it is best that you immediately stop all operations on your laptop and let it be looked at by a professional.

What to do with a swollen battery?

The only correct and best way to resolve an issue of a swollen battery is replacement of the entire battery. The swollen batteries cannot be fixed or healed – just recycled and replaced. Even if your device still works, the battery must be replaced immediately. Using the device or leaving it connected to power can pose risks. 

Once a battery starts to swell, it is considered compromised in every way and a replacement is the only way to avoid further damage to your laptop. And most important: At the first sign of battery swelling, back up any crucial data ASAP, discontinue the use of the laptop and discharge it by disconnecting the AC Adapter and letting the battery drain.

Do not press on the swollen battery (or screen or casing that’s popping up).

If your device has a user-removable battery, you can try to carefully remove it and place it in a container in a safe cool place. Be sure to wear eye protection and gloves. Place the device on a flat surface, previously removing all the flammable objects from the vicinity. The laptop should first cool down. Later you could try removing the battery – remember to be careful. Don’t try wedging it up or prodding it with sharp devices, or flex it in a swollen state, and whatever you do, do not puncture the swollen battery—some of the gases could be harmful.

If you’re not 100% sure whether the battery is at fault, you find it hard to remove the battery or are afraid to do it on your own – take your laptop to a service store.
