Thousands of battery manufacturers , battery research institutes and laboratories use it as their primary testing partner for their various testing activities . Battery researchers and scientists, battery manufactures , importers and exporters, you can always choose the most appropriate Neware battery testers for battery quality check , battery performance tests, battery material research , and battery mass production lines .  Accurate Timing Most of us are considering the voltage and current accuracies are the all important factors of a battery tester , but actually timing accuracy is of the same importance . Capacity or energy is calculated on time basis with the voltage and current measured , thus the timing accuracy will greatly affect the capacity calculated. To a general constant current or other constant testing regimes , this effect may not that easy to be observed . Left is from Neware , right is from another supplier in the marke . Data Security Neware battery testing system utilizes LAN as the main framework to transfer data . This provides the most flexibility and reliablity to your system deployment . When you look down into Neware battery tester , its unique Middle Machine architecture provides another enhancement layer to the data security issue . Moreover , this MM is an embedded system that allows you run tests even your LAN is down .
