Neware VRLA 12V Lead Acid Battery Capacity Discharge Tester Cycle Life Analyzer
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 .
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 .
