Safely Operate your Symmetra LX with refreshed SYBT5 boards...

DON'T REMOVE THE SAFETY ON YOUR SYMMETRA.

At the heart of any good UPS is a great battery. And the Symmetra LX SYBT5 Battery is one of the most advanced batteries. However many people try to re-use or bypass the safety and performance features built in to the APC SYBT5 by using refilled old battery trays.

Inside the SYBT5 is a microchip and board that logs and alerts the main Symmetra if there any problems. Too many refiller battery firms, either bypass or re-use these chips.

Understanding the Syntelligence

There are 3 features on the SYBT5 board that allow you safely operate your Symmetra. 1) Self Check Triggers: The battery is checking a number of values and listening to the Symmetra. If it detects admonimalities, it flags itself bad and alerts the Symmetra.

2) Shunt value: This value differs for each board and helps the Symmetra produce accurate load and runtime values.

3) Serial # and Date of Manufacture: Used to help the end user, but also to properly identify and communicate with the battery.

The Sybester also works on dead battery trays or empty trays. Just press the Activation button to get these values.

A properly calibrated SYBT5 board with Syntelligence protects and improves performance of your Symmetra.

Get your own fresh SYBT5 board

We have developed a SYBT5 board that you can install in your old tray with all new values and safety features found in genuine APC SYBT5 batteries.

You will get a board with unique 2024 serial number, new date of manufacturing, reset Calibration factor, tested Shunt value, reset Self check triggers, and new temperature alarm sensor.

We can even program your own unique serial # for resellers.

Dangers of using refiller batteries

A large used Symmetra vendor sold a customer some refilled SYBT5. A year later, we got an emergency call to help a Symmetra that was overheating and faulting. When we arrived the datalogs on the Symmetra showed the batteries as Brand new and working fine. But the internal frame temperature sensor had been triggered. Yet, the SYBT5s were swollen and still hot-to-the-touch. We openned up the trays and found the vendor had installed blank chips in the SYBT5 trays.

What likely happened is one battery in the tray had a problem. But since there was no Syntelligence, the Symmetra did not get any of this information. The failing battery couldn't recharge, yet the Symmetra kept charging it causing excess heat. Next the heat spreads to other batteries and again without any feedback, the Symmetra is blind to the problem. Eventually the heat in the batteries causes the frame itself to overheat and trigger the frame overheating fault and shut down the load.

In this case the lack of a proper SYBT5 board caused all 4 SYBT5 batts to fail early, other module failures and a disasterous extended outage.
