8-Point Battery Safety Check
Since the Galaxy Note7 recall, we’ve re-assessed every step of the smartphone manufacturing process and developed the 8-Point Battery Safety Check. It involves putting our batteries through extreme testing, inside and out, followed by careful inspection by X-ray and the human eye. We are making a stronger commitment to safer devices.
-
Durability Test It starts with enhanced battery testing, including overcharging tests, nail puncture tests and extreme temperature stress tests.
-
Visual Inspection We visually inspect each battery under the guideline of standardized and objective criteria
-
X-Ray We use X-ray to see the inside of the battery for any abnormalities.
-
Charge and Discharge Test The batteries undergo a large-scale charging and discharging test.
-
TVOC Test(Total Volatile Organic Compound) We test to make sure there isn't the slightest possibility of leakage of the volatile organic compound.
-
Disassembling Test We disassemble the battery to assess its quality, including the battery tab welding and insulation tape conditions.
-
Accelerated Usage Test We do the intensive test simulating accelerated consumer usage scenarios.
-
△OCV Test(Delta Open Circuit Voltage) We check for any change in voltage throughout the manufacturing process from component level to assembled device.
