Frequently Asked Questions (FAQ)

1. What devices are compatible with the S9185FA battery pack?

It is specifically designed for Yokogawa GX10, GX20, GP10, GP20, and FX series paperless recorders. Compatibility with other models is not guaranteed.

2. How long does the battery last during a power outage?

Typically, the S9185FA can provide 30 to 60 minutes of backup, depending on recording activity, display usage, and connected modules.

3. How will I know when the battery needs replacement?

Yokogawa devices monitor the battery’s condition. You’ll see a warning message when capacity drops below safe levels or when it fails to hold charge.

4. Is the battery charged while installed in the recorder?

Yes. The recorder charges the battery automatically when connected to AC power. No external charger is needed.

5. Can the battery be replaced while the device is powered on?

No. To avoid electrical risk or data corruption, always power off the device and disconnect it from mains before replacing the battery.

6. What protections are built into the S9185FA battery?

It includes built-in circuits for overcharge, over-discharge, and short-circuit protection, ensuring both battery and device safety.

7. How should I store the battery if it’s not in use for a long time?

Store it in a cool, dry place between -20°C and +40°C, ideally at around 40% charge. Avoid fully charged or fully depleted storage.

8. What is the typical lifespan of this battery pack?

Under normal use, the battery lasts 3 to 5 years or approximately 500 charge cycles before noticeable degradation occurs.

9. Is the S9185FA certified for air or sea shipping?

Yes. It meets UN38.3 transportation safety standards, so it’s safe and legal to ship internationally under lithium-ion battery regulations.

10. Can I use this battery with older Yokogawa recorders or controllers?

Only if those devices specifically support the S9185FA. Using it with incompatible hardware may prevent proper charging or damage internal components.
