✅ Confirmed Compatibility

Compatibility depends on both the controller series and its physical construction. This slide-in cartridge is confirmed for compatible LCD-mounted control units that specify A02B-0323-K102 and select robot controllers that specify A98L-0031-0028. It is not the wired A02B-0200-K102 battery used by stand-alone control units. Verify the original part number, cartridge housing, latch, and connector before ordering.

⚙️ Fit Notes

• Match A02B-0323-K102 or A98L-0031-0028 and compare the complete cartridge shape, latch, and connector with the original.
• Do not substitute the wired A02B-0200-K102 battery used by stand-alone control units or a different battery with a similar voltage.
• Back up programs, parameters, and other control data before replacement because incorrect service or an extended loss of battery power can erase memory.
• Follow the exact machine or controller maintenance procedure. Power-state and replacement-time requirements vary, and service should be performed by qualified personnel.
• This is a primary non-rechargeable lithium battery. Do not charge, short-circuit, puncture, crush, or incinerate it, and dispose of it according to applicable regulations.
