3GB280-F - 3.6V 280mAh Rechargeable PLC CNC Replacement Battery

Restore reliable memory backup power with this 3GB280-F rechargeable replacement battery designed for compatible PLC, CNC, servo amplifier, and industrial control applications. This 3.6V battery is commonly used in Mitsubishi and Mazak-related control environments where stable backup power is needed to preserve stored data and machine settings. It is a practical replacement for weak, aging, or failed original backup batteries in supported systems.

This battery is widely cross-referenced in the aftermarket with the Mitsubishi MR-S11 / MR-S12 battery family and related replacement numbers such as 3/V200H, C0308, and GB250H-3F. Mitsubishi’s own parts catalog result for 3GB280-F identifies it as obsolete and directs users to 3/V200H, which aligns with cross-reference listings from multiple battery suppliers.

Technical Specifications

• Model Number: 3GB280-F
• Voltage: 3.6V

The 3GB280-F is consistently listed as a 3.6V rechargeable backup battery, while chemistry references vary across sources between older Ni-Cd labeling and newer Ni-MH style replacements. For a customer-facing listing, the safest match point is the model number, voltage, capacity class, terminal style, and application family.

Interchangeable / Replacement Part Numbers

3GB280-F, 3/V200H, V200H-3ME, 3GB170-F, 3HB320-F, C0307, C0307-1, C0308, GB150H-3F, GB250-3FB2, GB250H-3F

These cross-references are repeatedly associated with the same Mitsubishi MR-S11 / MR-S12 backup battery family across multiple battery suppliers and replacement catalogs.

✅ Confirmed Compatibility

Please note that the following list is not exhaustive. Compatibility depends on your system's specific configuration. It is essential to verify compatibility with your system or control manufacturer prior to installation.

✔️ Mitsubishi MR-S11 Series: MR-S11 series servo amplifiers and related control applications
✔️ Mitsubishi MR-S12 Series: MR-S12 series servo amplifiers and related control applications
✔️ Mazak Servo Amplifier / PLC Logic Control Systems: Compatible with many Mazak control applications that use the Mitsubishi MR-S11 / MR-S12 battery family
✔️ Mitsubishi CNC Control Battery Applications: Compatible with control assemblies using original battery references 3GB280-F, 3/V200H, C0307, C0308, GB150H-3F, GB250-3FB2, or GB250H-3F
✔️ Industrial PLC / CNC Backup Applications: Suitable for supported industrial equipment requiring a 3.6V rechargeable backup battery with the same physical style and screw-tab connection layout

The strongest repeatable compatibility evidence I found ties this battery family to Mitsubishi MR-S11 and MR-S12 servo amplifier applications, with several aftermarket references also explicitly calling out Mazak servo amplifier / PLC logic control use.

⚙️ Fit Notes

• Please match the exact battery model number on your original pack before ordering.
• Verify the voltage, terminal style, mounting layout, and overall battery shape against your original unit.
• This is a rechargeable backup battery intended for supported control circuits that charge and maintain this battery type.
• Because source listings differ on whether older originals were labeled Ni-Cd or replaced by newer Ni-MH equivalents, the most important fit points are the 3GB280-F family number, 3.6V rating, and physical connector / mounting style.
• If your original battery uses a different plug, wire lead, lithium chemistry, or non-rechargeable format, this will not be the correct replacement.
• Professional installation is recommended for CNC, PLC, and servo amplifier applications where parameter loss may occur during battery replacement.
