When the machine is equipped with Fanuc absolute encoder. System such as an absolute pulse coder or absolute linear scale, there is a Fanuc Lithium battery for them separately from the battery for memory backup.

Replacing Fanuc batteries on Fanuc Alpha SVM (Servo amplifier)
Procedure for replacing batteries for absolute pulse coder
1 Turn on machine (CNC) power. Replace the battery under the emergency stop state for safety, to escape the machine from moving during the replacement work. If the battery is replaced while the power is off, the memorized absolute position data will be lost, thus necessitating a reference position return operation.
2 Remove the battery case on the front panel of α series servo amplifier module (SVM). The battery case can be removed by holding the top of the case and pulling the case towards you.
