1 , The Neware battery tester models listed below here in different categories are the most popular ones chosen by our customers , so if you belong to one of the following category , then it might be easier for you to find out the battery tester that meets your requirement based on your peers choice .
2 , 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 .
3 , CT4000, based on Neware 4th generation testing system , entered into market in 2008 .
4 , It supports some testings as follow , EV battery pulse charge/discharge , DCIR - Direct Current Internal Resistance , cycle life and rate .
Data Security
1 . Neware battery testing system utilizes LAN as the main framework to transfer data . This provides the most flexibility and reliablity to your system deployment .
2 . 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 .
Accurate Timing
3 . 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 .
4 . 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 .
