※Depending on the operating conditions, the reference for replacement is that the total power OFF time after the battery has been connected to the DU reaches about 10 years.

When 16 DUs are used as an example;
1. ABS batteries are connected to all the DUs. → 10 years each
2. One ABS battery is connected to DPU only. → 10 years / 16 units = 7.5 months

The model number printed on the battery itself is the last three digits, but this third digit is a compatible revision number and is not required when ordering.
Please tell us the model number of this list.

<Precautions for Absolute Battery Replacement>
If the absolute battery is removed while the power is off, home return is not completed.
Perform the home return operation after turning the power OFF and ON again.
(For details on how to replace the controller, refer to the controller's manual.)
