Cameron Sino DS-CS-MMR300SL for Mitsubishi MelServo

This 3.6V 2000mAh Li-MnO2 primary battery replaces the MR-J3BAT in Mitsubishi MelServo MR-J3 series servo amplifiers. It suits maintenance engineers and automation technicians who need a direct-fit backup for position-data retention. The grey cell delivers 7.2Wh and matches the original form factor for OEM compatibility.

Installation ease and common issues

The battery slots into the amplifier's dedicated holder without tools, using the existing connector orientation. Polarity is keyed so reverse insertion is physically prevented. The main risk is fitting a rechargeable cell by mistake; only a non-rechargeable Li-MnO2 type is safe for this circuit.

Limits of primary Li-MnO2 chemistry

As a non-rechargeable cell it must be replaced once the stored charge depletes, typically after several years of hold-up duty. It cannot support cyclic loads or act as a main power source. Operating temperature range and shelf-life limits are defined by the chemistry and are not extendable by the user.

Questions about this item

How do I confirm the battery is working after installing it in a Mitsubishi MelServo MR-J3?

The servo controller should power up and retain its position data without a low-voltage alarm, showing the 3.6 V 2000 mAh cell is delivering the rated 7.2 Wh.

What comes in the box and what must I source separately?

The pack contains one grey Li-MnO2 primary cell measuring 68.40 x 24.45 x 20.83 mm; no charger, cable or mounting hardware is included because the battery is non-rechargeable.

Which capacity should I choose for a MelServo MR-J3-B4 that needs a direct MR-J3BAT replacement?

This single 3.6 V 2000 mAh 7.2 Wh version is the exact OEM-capacity match for the MR-J3BAT part number listed for all compatible MR-J3 models.
