Determining battery lifetimes is beset with difficulties. Performance data are not generally available and costly to generate since large numbers of batteries must be tested to destruction. Furthermore, the required test period to verify the predictions is often greater than commercial decision lead time. Charge – discharge times for high capacity batteries are very long and using accelerated life testing to determine battery lifetime is most likely to lead to misleading results since battery life depends on temperature, rate and depth of discharge and the test conditions used to accelerate the occurrence of failures are quite likely to introduce new and unrepresentative failure modes.

Comparing with some battery testing systems in the market, there's another amazing characteristic of Neware battery tests - low dependence on PC. When running the tests, our battery testing instruments don't depend on PC too much, even in some emergency your PC doen't work/shut down/restart/reset, our instruments still work well offline.

Question: We have some Neware battery cyclers that we would like to integrate in our automated data processing system. Is there a way to automatically convert or save the cycling data to CSV (Excel) or text format? We need to have a way to get the data in a common format without human intervention. We know that data can be saved to Excel by going to the channel and exporting the data, but we need to have it done automatically, for example as Macro/script or in command line.

For many customers who are doing battery material research, it's important fro them to get the 'capacity density' of the battery.

Some customers don't know by using our software, it's very easy to get the capacity density the need.

Maybe you have already used BSTDA, right? One of our powerful and free NDA file analyzer, by right click in BTSDA and choose capacity density, then it'll automatically calculate the values for you, just like the following picture, isn't it easy and amazing?

For regular battery constant current charge tests,when you use constant voltage to charge the battery, the current flows into the battery becomes smaller and smaller as time goes by, right?
There must be a point for you to stop the charge, the end condition of that point is supposed to be a very small current.
That's why for CV_Chg the end condition is current, that's a necessary set up.
But that's just for NORMAL tests, what if you want to do the tests without setting up the current end condition?
Such as if you need a step to simply hold voltage at 2.7V for extended amount of time.
What can you do with that? Is it possible for Neware BTS software(Battery Testing System) to get the job done?
The answer is YES!
For achieving this purpose, you have to modify the BTS.ini file in the installation directory.
Please close the BTS application firstly, go to the installation directory(normally C:\Program Files (x86)\NEWARE\BTSClient7.5.5) and open the BTS.ini file.
Locate the following segment and modify the value from 0 to 1.
[CVCHARGEMODE]
MODE=1
Then save the BTS.ini(you may be asked for the administrator rights if you are using Windows 7 or higher edition of Windows OS).
Restart the software and you'll notice now the CV_CHG can work without setting up the current end condition.
BTW: As you may already knew, long time Chrage/Discharge may cause hazards to battery or supercapacitor, please be careful.

Most customers know that BTSDA software is designed for the NDA file format, but can we write to another format such as .CSV or .txt?

The answer is definitely YES. Please refer to the following screenshots, it's very easy and flexible.

Generally, the capacity comes out from a battery(discharge capacity) will be less than the capacity comes into a battery(charge capacity).

But for some customers, when they perform charge and discharge operation with Neware BTS software at the beginning, it's strange to see the discharge capacity is more than the charge capacity.

For some BTS3000 COM port edition battery testers customers, they may meet COM port errors sometimes.

And for customers who are using TC5.3 software, when they check the testing data, there's also possible for them to meet some minor problems in the BTSDA software.

Some customers asked us about the cell grouping or grading of Neware BTS software. Is it possible for the Neware BTS software be used for cell grouping or grading?

The answer is yes. Neware BTS software can be used for cell grouping or grading and it's not difficult to use.

Please refer to the following screenshot, there are 3 steps for you to have access the Battery grading/grouping function in BTS software.

By clicking the buttons in the following pictures, you can switch different views in Neware BTS software client.
