Quickly Measure, Check and Determine the status of any APC SYBTU1 type battery tray.

Simply plug in the SYBester into the back of the SYBTU1 or SYBTU2 tray and its immediately gives you the Voltage, Thermister value, and Battery Class Resistor Value.

AND with Sybester3 ... you can Load test the battery tray, and use the SybesterLIVE! companion Android APP to download datalog tests of battery

Sybester3 comes with case, Android phone with SybesterLIVE App and cables.

Developed by Robert Furmanak as a quick tool to use around the GreenLightUPS shop.

from his original LinkedIn Post:
We test and rebuild a lot of SYBT batteries, and we needed a more efficient way of checking them. Having a technician insert voltmeter probes into the battery terminals is inefficient and error-prone, and a custom cable to connect a standard voltmeter to the battery terminals is only slightly better, for the technician would still have to make 3 separate measurements. The tech would also have to switch between reading resistance and voltage. The testers I designed make the task much easier, and they are inexpensive to make.
