Mr. SAVIN Jean-FrancoisWe have been using Neware benches for testing our primary cells and batteries for several years. We are quite satisfied about the quality of this type of equipment and we find always good and very reactive feedback from their after-sales service to help us in specific case.
Prof. Lv LiWe have been using Neware battery testing system for many years. We are focused on different electrochemical tests of lithium-ion batteries. The Neware machine is easy to be used and the program is easy to set. We have conducted charge-discharge cycling for more than 5000 cycles and the machine showed very good stability, which helped us to obtain
Mr. Frank GroenVarious neware testing systems have been equipped our laboratory for years and serves very good. We use them for many kinds of tests. Easy to handle the tests and data is well organized for our reporting work. The most important thing is the measurement and control are quite accurate and reliable.

DCIR - Direct Current Internal Resistance
a . Direct current internal resistance of batteries is the r esistance of current flowing through the battery , with the standard unit of measurement called the ohm .
b . The value of DCIR is not fixed , and varies depending on multiple factors , such as battery materials , electrolyte concentration , temperature , and depth of discharge .
c . The variation of DCIR has a great influence on battery discharge performance , especially for high power batteries . In general , the better the battery , the lower the internal resistance .
d . Therefore , most battery manufacturers identify DCIR as a key indicator to evaluate battery quality . The method of DCIR measurement is to inject high current into the anodeand cathode of the battery in a short period , and then record the changes of battery voltage and charge / discharge current .
e . To calculate DCIR by Ohm Law , voltage variation is divided by current variation.
