Keep your collaborative robot operating reliably with the genuine FANUC CRX robot memory backup battery, part number A98L-0031-0040#A. This lithium battery pack is designed to preserve critical robot data including absolute encoder position and controller memory during power loss or shutdown.
Used across the full CRX collaborative robot lineup from FANUC, this OEM-spec battery helps prevent data loss, alarms, and costly re-mastering procedures.
Each FANUC CRX robot requires two (2) battery packs:
- 1 battery for Axis 1–3
- 1 battery for Axis 4–6
Replacing both at the same time ensures full encoder backup protection.
Compatible with All FANUC CRX Models:
Including (but not limited to):
CRX-5iA • CRX-10iA • CRX-10iA/L • CRX-20iA/L • CRX-25iA • CRX-30iA

Long service life & industrial-grade reliability
If the FANUC CRX backup battery (A98L-0031-0040#A) gets weak or dies, the robot will begin showing memory and encoder-related alarms. Because the CRX uses absolute encoders, battery failure primarily affects position retention and controller memory backup.
Below is what an operator will typically experience if the battery goes dead:
SRVO-062: BZAL Alarm – SRVO-062 BZAL (Battery Zero Alarm)
This is the most common alarm and indicates the encoder lost absolute position memory.
