A bulging battery is not just a performance problem — it is a safety emergency. A swollen lithium-ion battery is at risk of venting toxic gases, catching fire, or in extreme cases, exploding. If your phone's back cover is lifting, the screen is being pushed outward, or you can feel a lump under the casing, stop using the phone immediately and bring it to Pro-Logic Technologies.
Why Batteries Swell
Lithium-ion batteries swell due to internal chemical breakdown. When the electrolyte inside the battery cell degrades, it releases gas that has nowhere to go except outward, expanding the battery pouch. Causes include:
- Old age — batteries past their cycle life begin degrading internally and are prone to swelling.
- Overcharging — leaving a phone plugged in at 100% for extended periods, particularly with cheap chargers, accelerates chemical breakdown.
- Physical damage — a punctured or bent battery degrades rapidly and can swell within days.
- Heat exposure — leaving a phone in direct sunlight, in a hot car, or under heavy processing load regularly accelerates electrolyte breakdown.
- Manufacturing defects — less common, but some batches of batteries have defective cells that swell prematurely.
What You Should and Should Not Do
Do: power off the phone, keep it away from flammable materials, and bring it to us as soon as possible.
Do not: attempt to pierce, squeeze, or remove the battery yourself. Do not put it in a drawer and continue using it. Do not charge it further.
Our Safe Removal and Replacement Process
At Pro-Logic Technologies, our technicians are trained in safe lithium battery handling. We carefully open the device — taking extra care not to puncture the swollen cell — and remove the battery using proper tools and technique. We inspect the interior for any damage the swelling may have caused to surrounding components, particularly the display cable and motherboard.
We then fit a quality replacement battery and test charging and power management before returning the phone to you.
A swollen battery is an emergency. Do not delay — bring your phone to Pro-Logic Technologies today.
