  • Battery pack size1-pack
  • Direct Mitsubishi A6BAT MR-BAT PLC replacement
  • 6 V lithium chemistry for stable backup power
  • 1700 mAh capacity supports extended runtime
  • 17 mm by 33.5 mm form factor fits original slot

Direct Replacement for Mitsubishi A6BAT PLC Units

This 3.6V lithium cell is built to match the original Mitsubishi A6BAT MR-BAT specification for memory back-up in PLCs, servo drives and numerical control equipment. It delivers 1700mAh capacity in a 17mm by 33.5mm cylindrical form factor. The Tank brand cell is manufactured in Japan and supplied as a single unit.

Verify Voltage and Physical Dimensions Before

Confirm that your equipment requires a 3.6V lithium primary cell and that the battery compartment accepts a 17mm diameter by 33.5mm length package. Check the existing part number against A6BAT, MR-BAT or ER17330V to ensure correct polarity and connector layout. This pack contains one battery; order additional units if multiple slots need replacement.

Low Self-Discharge Chemistry Suited to Long-Term

The lithium thionyl chloride chemistry provides a stable 3.6V output with minimal self-discharge during extended standby periods. Normal operation in memory back-up roles draws microampere-level current, so the cell runs cool and silent without active cooling. The 1700mAh rating supports multi-year service intervals in typical PLC and alarm system applications.

Questions about this item

What comes in the box and does the Mitsubishi PLC need anything else?

The pack contains one 3.6 V 1700 mAh ER17330V cell measuring 17 mm by 33.5 mm; no extra hardware is required for the memory back-up slot.

Which version of the A6BAT replacement should I choose for my PLC?

The listed model A6BAT-04 is the direct 2/3AA lithium replacement rated at 3.6 V and 1700 mAh for Mitsubishi equipment.

How long will the 1700 mAh capacity actually last in a servo motor back-up role?

At 3.6 V the cell stores roughly 6.1 Wh, which typically powers a PLC memory circuit for several years before replacement is needed.
