Cameron Sino Replacement Battery for MelServo MR-J3 Series

SKU CH-VGW4-4AKKG

Replacement battery for MelServo MR-J3 series servo drives, built with high-quality cells for reliable power and easy installation

  • Reliable power for industrial servo drives
  • Compatible with MelServo MR-J3 series models
  • High-quality cells extend battery lifespan
  • Meets or exceeds original manufacturer specifications
  • Simple installation process for quick replacement

Product Identity

This Cameron Sino replacement battery is built for MelServo MR-J3 series servo drives including the MR-J3, MR-J3-A, MR-J3-A4, MR-J3-B, MR-J3-B4, MR-J3-T and MR-J3-T4 models. It supplies reliable power to maintain encoder memory and system parameters in industrial automation equipment. Technicians servicing these specific drives will find it a direct-fit solution. Buyers needing batteries for other servo families or consumer devices should look elsewhere.

Installation Notes

The battery is designed for simple user replacement without special tools, typically accessed through a dedicated compartment on the drive unit. Ensure the servo system is fully powered down and follow the manufacturer's safety lock-out procedure before opening the enclosure. Polarity must match the original orientation exactly; reversed connection can damage the drive's control board. Static precautions are advised when handling the new cell.

Pre-Order Checks

Confirm your drive's exact model number against the supported list: MR-J3, MR-J3-A, MR-J3-A4, MR-J3-B, MR-J3-B4, MR-J3-T or MR-J3-T4. Verify the physical dimensions and connector style of your existing battery match the replacement, as revisions may exist. Check the installation date of the current cell to gauge remaining service life. This product is not suitable for non-MelServo equipment or earlier MR-J2 series drives.

Questions about this item

How can I confirm the battery is working correctly after installing it in my MelServo MR-J3 drive?

After installation the servo drive should power up without a low-voltage alarm, hold position data during a power cycle and show normal status LEDs; if the controller reports a battery fault or loses encoder position on restart, re-check the connector orientation and seating.

What comes in the box and is any extra hardware or cable needed for the MelServo MR-J3-A4 model?

The package contains the Cameron Sino replacement battery only; no additional cables, mounting brackets or tools are supplied, and the original connector on the MR-J3-A4 mates directly with the battery leads.

Which version should I choose for a MelServo MR-J3-B4 drive?

This single Cameron Sino battery is listed as compatible with the MR-J3-B4 along with the MR-J3, MR-J3-A, MR-J3-A4, MR-J3-B, MR-J3-T and MR-J3-T4, so no separate version or capacity option exists — the one item fits all listed models.
