This is How Intex Tests a Smartphone Battery For Reliability

by February 14, 2017 0 comments

Recently, INTEX, installed a highly sophisticated, soon to be BIS accredited, Battery Reliability & Safety Laboratory in one of the manufacturing units in NOIDA. This lab is motivated to fulfill the requirements of the UN 38.3 safety standards. INTEX is the first organization to install such a lab setup in India and with this lab it has raised the bar for industrial standards to support customer safety, for other mobile phone manufacturers.

There are 8 tests which comprise the UN 38.3 safety standards. The batteries are selected on a random basis from the battery lot under quality assurance examination. The 8 tests which are carried out are:

1) Altitude test: As the altitude from the sea level rises the air pressure decreases which could have a detrimental effect on the batteries. This test allows us to segregate the subpar batteries. In this test, we set the chamber pressure to only 12% of the atmospheric pressure. The test is carried out for a period of 6 hours. The observation period is 24 hours after which the battery is checked for leakages, swelling or fire. If the battery passes the test then the next stage test is carried out.
