An inherent characteristic of lithium-ion polymer batteries is the possibility of bulging, which is closely related to the age of use, number of charge cycles, or exposure to high temperatures. Due to its compact internal structure, the Dell Precision 5470 battery is located close to the CPU cooling module, and prolonged high-temperature operation will accelerate this process.
If any of the following occurs, please stop using your computer immediately:

Uneven bottom of the chassis – It wobbles like a seesaw when placed on a table.
Enlarged gaps in the casing – Abnormal gaps appear around the touchpad or palm rest.

Do not continue charging or using the computer.
Do not attempt to puncture the battery with a sharp object to release gas – This is extremely dangerous and could cause a fire or explosion.
Do not forcefully squeeze or bend the battery.
If the battery is stuck inside the chassis due to bulging and cannot be removed, contact Dell technical support immediately. Do not attempt to pry it open.
