Simply plug the SYBester into the SYBTU1-PLP tray and instantly get voltage, thermistor health, and battery class.
Gives you the string voltage of the battery tray to measure general health. From 20-120volts
Gives you the resistor value of the heat senstive Thermistor. Use the value to guage environmental health.
Quickly differentiate between the battery class V66/C10/B20/C69 by noting the resistance value.
Simply plug in and get all the values you need. No need to fumble with a multimeter, the SYBester's quick connect mounts securely on the back of the SYBT tray.

Robert Furmanak's SYBester design is a clean and affordable design. Using just 13 parts, the version 1 design delivers 3% accuracy, ideal for cursory field testing. Future versions may add a battery load test.
Having a technician insert voltmeter probes into the battery terminals is inefficient and error-prone, i knew i could find a better way.Robert Furmanak, Inventor and Engineer at GreenLightUPS
