Battery swelling is a type of surprising issues that may usually catch us off guard. If left unaddressed, it might probably inflict critical inside harm to your machine and is a security hazard. However what causes this regarding difficulty, and what steps can you are taking to stop it?
Overcharging
Holding your machine plugged in after it’s absolutely charged and regularly charging it to 100% are main causes of battery swelling. Whereas most lithium-ion batteries cease drawing energy as soon as absolutely charged, a steady energy provide retains the battery at 100% for prolonged durations. This could disrupt the battery’s chemical processes, releasing gases and inflicting it to swell.
To keep away from overcharging, enable your device’s “smart charging” feature to restrict charging past 80%. If this selection isn’t obtainable, monitor your machine whereas charging and unplug it when the battery reaches round 80-90%. Moreover, keep away from in a single day charging or leaving the machine at a full cost for prolonged durations.
Deep Discharging
Like overcharging, deep discharging—permitting a battery’s cost to drop too low—may also harm it. When some sorts of batteries discharge under their protected restrict, copper plating happens on the electrodes, which reduces capability and results in swelling over time. This course of additionally will increase inside resistance and generates extreme warmth, additional straining the battery.
To forestall this, do not let the cost drop under 20%. When the battery reaches this degree, plug it in to recharge. If you have to use a laptop computer unplugged for an prolonged interval, enable power-saving mode to decelerate discharge. Additionally, do not go away your machine in sleep mode for lengthy durations, as it might deeply discharge if left untouched for days.
Excessive Temperatures and Moisture
Excessive temperatures velocity up chemical reactions inside the battery. It releases extra gases that speed up degradation and may result in swelling. Equally, excessive moisture ranges may cause condensation between the terminals, rising the danger of a brief circuit.
To guard your battery, you could avoid exposing it to extreme temperatures or high humidity. Maintain it out of direct daylight, cost it in environments with balanced temperature and humidity, use a water-proof case or cowl close to water sources, and place silica gel packs in your machine bag to soak up extra moisture.
Bodily Harm
Bodily harm, equivalent to dropping the battery or subjecting it to extreme impacts, can compromise its protecting layers. Extreme strain could rupture the casing, exposing the battery to air or moisture. This publicity can disrupt chemical reactions, launch gases or harmful acids, and set off inside quick circuits, resulting in surprising swelling or violent fires.
To forestall such points, deal with your battery and machine with care. Keep away from putting your laptop computer in overfilled luggage the place strain can construct up. Additionally, preserve it away from areas liable to unintended drops, and all the time use a well-cushioned suitcase when touring to guard it from surprising impacts throughout unintentional falls.
Utilizing Non-Authentic Chargers

Charging your machine with a low-quality or counterfeit charger may also result in battery swelling. These chargers usually present inconsistent or extreme voltage and present, which places undue stress on the battery’s inside chemistry. Over time, this could harm the battery cells and speed up swelling.
To keep away from this, all the time use authentic chargers and cables really useful by the machine producer. Should you want a substitute, use manufacturer-approved or licensed third-party chargers that meet security requirements. Moreover, usually examine your charger and cables for indicators of wear and tear or harm, and change them promptly if wanted.
Battery Getting older
Over time, the repeated cost and discharge cycles naturally trigger battery degradation. As the inner chemical parts put on down, the battery’s capability and effectivity decline. Because the deterioration progresses, inside resistance will increase, which accelerates gasoline manufacturing, resulting in overheating and swelling.
When you can’t stop the ageing of a battery—because it’s a pure course of—you possibly can decelerate its deterioration by following greatest practices. Keep away from overcharging, chorus from frequent full discharges, preserve the cost degree between 20-80%, use authentic chargers, and shield the battery from extreme warmth, moisture, and bodily harm.
Manufacturing Defects
Though much less widespread, a built-in or substitute battery could swell if it has inside manufacturing defects, equivalent to improper sealing, defective chemical mixtures, or faulty parts. These points can disrupt chemical reactions, resulting in overheating and quick circuits, which may contribute to swelling.
To forestall this, all the time purchase your battery from respected manufacturers or approved retailers. Keep away from low-cost, unbranded third-party replacements that won’t meet security requirements. In case your new battery takes longer to cost, depletes rapidly, or shows other warning signs, contemplate changing it to stop swelling and additional harm.
Defective Battery Administration System
The battery administration system (BMS) controls charging, discharging, and temperature regulation. It tracks variables like voltage, present, and state of cost to make sure protected battery operation. If the system malfunctions, it might result in overcharging, undercharging, or extreme warmth buildup, which may stress the battery and trigger swelling.
To forestall battery harm or swelling brought on by a defective BMS, look ahead to indicators like error messages, incorrect battery cost estimates, overheating, charging points, or failure to cease charging on the set threshold. Should you discover these indicators, have your machine checked by a technician for BMS points. Additionally, calibrate the battery to make sure the system works accurately.
Poor Restore or Upkeep
Improper upkeep or restore, equivalent to utilizing incorrect instruments, damaging the battery’s protecting casing, exposing the battery to moisture or excessive temperature throughout repairs, may also hurt your battery and result in swelling over time. Additionally, over-tightening screws or failing to put in the battery correctly may cause related issues.
To keep away from this, all the time have your battery repaired or changed by the producer. This ensures your battery is protected against harm and helps preserve your guarantee. If that is not doable, do not try it your self—search assist from knowledgeable from a trusted service middle. When changing your battery your self, remember to observe detailed guides and use the correct instruments.
Now that you understand the elements that may trigger your machine’s battery to swell, you could take proactive measures to keep away from harm. By following the ideas above, you possibly can preserve your battery in good situation for a very long time. Often test your laptop computer battery; if it begins to swell resulting from ageing, change it to keep away from any potential harm to your machine.
