What is a Battery tester?

A battery tester is a device that can easily measure the internal resistance and voltage of a battery with a probe in order to diagnose the deterioration of a secondary battery. Normally, the internal resistance of a secondary battery increases and its performance gradually decreases as it is repeatedly charged and discharged. The secondary battery for backup may also deteriorate over time, so it is important to diagnose its performance in advance. With a battery tester, you can immediately diagnose battery performance without shutting down the device. Furthermore, the data is saved in the internal memory and can be easily managed by transferring it to the PC.

Application of Battery tester

１．Electric Vehicle Batteries – Battery testers are used to check the health and performance of batteries in electric vehicles (EVs) to ensure they have sufficient charge capacity and are safe for use.
２．Mobile Phone Batteries – Battery testers are employed to measure the charge and discharge cycles of mobile phone batteries, checking for any signs of wear or degradation over time.
３．UPS (Uninterruptible Power Supply) Batteries – Testing is done on UPS batteries to ensure their reliability and performance in providing emergency power during blackouts or power fluctuations.
