Quality control of our laptop batteries :
Throughout our manufacturing process and at the end of the line, we carry out quality controls to ensure that each and every battery component is reliable and safe.
At the end of the cycle and before it can be sold and shipped, each of our batteries undergoes four tests that will ensure that customers are fully satisfied with the quality of our products and that the batteries will be able to power their laptops in a sustainable manner. The 4 steps :
Voltage resistance test :The first test includes verifying that the device will be able to operate safely at the rated operating voltage. We also check the tolerance capacity due to instantaneous conversion, overvoltages and similar overvoltage phenomena.
Charging and discharging test :The charge and discharge test focuses mainly on different scenarios such as battery life test, simulation test of operating conditions, capacity test, consistency check, Of course, it checks the Charge Cycle, in particular it determines the maximum voltage that the battery charging process can reach. Once this voltage is reached, the battery management system requires the charging process to end; the charge cut-off voltage is usually slightly lower than the maximum open circuit voltage allowed by the battery. Discharge cycle is also checked to determine the variation in battery current and voltage during discharge.
Aging test :The main steps of the test are as follows: The ageing test consists of charging and operating the laptop batteries at a certain temperature or under a certain load, and then checking whether the product's performance index meets the technical requirements after a period of time or cycle, thus determining the stability, safety, lifetime and performance of the battery.
Laptop test :Once all other tests have been completed, there is one last step before the laptop battery is declared compliant. Every battery must be passing test from laptop to ensure product quality and fiability
