OEM Best battery tester price Manufacturers – GDKH-10 Battery Activator – HV Hipot
General Information In all operating equipment and operating network systems with increasing informationization and automation, uninterrupted power supply is the most basic guarantee. Whether it is AC or DC uninterruptible power supply system, the battery acts as backup power source plays an important role in power source system. Usually, the battery is in the state of floating charge standby. Once the AC power is lost or other accidents, the battery becomes the sole energy supplier of the load. We know that in addition to the normal life cycle of the battery, some of the early failure of the battery may occur due to problems such as the quality of the battery itself, defects in materials, structures, processes, and improper use. In order to verify the standby time and actual capaci... -
