Lithium Polymer Battery Pack Swelling

Common causes of battery swelling include.

Lithium polymer battery pack swelling.

Lithium ion batteries removed from laptops can still be dangerous if a lithium ion battery has overheated smells or has distended take immediate steps for your safety. When disposing of a swollen lithium ion battery we strongly encourage you to call ahead and ask if the facility is equipped to accept a damaged battery and to check what the protocol is for bringing the battery in. Battery swelling is a failure mode associated with a type of battery cell technology called lithium ion polymer. Lithium polymer batteries lipo are the most recent battery chemistry.

Lithium ion cells can swell due to many reasons but somehow the issue of deep discharge swelling and the related hazards with charging such a battery seem to be widely underestimated. They are prone to mechanical damage catching fire and premature battery swelling. Beware the bulgy battery. They should be kept cool stored in partially charged state and protected from physical damage.

You need to discharge it completely first. This is something normal and always happens. Do not simply toss a swollen battery into a general battery recycling bin at your local big box electronics store. Caring for your lipo battery takes a little more care than your typical lithium ion battery.

This is not one of the systems that dell extended the battery warranty for you ll need to buy a replacement battery and if necessary the chassis parts assuming the battery was left in the system long enough to do damage.

If you have any doubts about your ability to do so safely power down and isolate the device and consult a professional repair technician immediately.

Lithium ion polymer batteries have become popular across the industry in recent years due to their slim and customizable form factor and longer battery useful life. Proceed with extreme caution and at your own risk when removing a swollen battery from an electronic device. However they have one significant disadvantage swelling. However the high power density of lipo batteries comes at a price.

In other words they become puffed up and lose their standard size. A swollen lithium ion battery may catch fire or explode.
