Battery is used on some servos (including Mitsubishi MR-J2S) to power encoder when machine is shut down. This permits use of quadrature encoder as an absolute position feedback (encoder runs on battery and keeps track of position during power down). If the batteres get drained too fast, check for any leaks. Measure battery current draw without encoder cable connected (any leak in the drive?), then with drive and cable only (leak in cable) and then with motor connected. Consult manual or manufacturer for normal value...
