❓ Frequently Asked Questions (FAQ)

• Q1: Which servo amplifiers work with MR-BAT6V1SET?
  • A1: It works with all MR-J4 series amplifiers that control rotary servo motors or direct drive motors. Does NOT work with linear servo motors. Also compatible with some MR-J3 series (check manual).
• Q2: How do I know when to replace the battery?
  • A2: Your MR-J4 drive will show alarm AL.25 (low battery voltage). Replace within 2 weeks to avoid losing absolute position data. We recommend yearly check.
• Q3: Can I replace the battery while the machine is running?
  • A3: Yes – keep servo amplifier power ON. Remove old battery and insert new one quickly. Position data stays safe. Never replace with power off – you will lose zero point.
• Q4: Is this battery the same as MR-BAT6V1 or MR-BAT6V1SET2?
  • A4: MR-BAT6V1SET includes battery + holder. MR-BAT6V1 is battery only (no holder). MR-BAT6V1SET2 is a newer version with same specs. All fit MR-J4, but SET version is easiest to install.
• Q5: Do you offer warranty and fast shipping?
  • A5: Yes – 12 months warranty. We ship within 12-24 hours via FedEx, UPS, or DHL. Global tracking provided. Contact sales@powergearx.com for urgent orders.

📘 Buying Guide – Do You Need MR-BAT6V1SET?

• ▪ Buy this if
  • ▪ You have an MR-J4 servo amp with rotary motor.
  • ▪ You want to keep absolute encoder position after power off.
  • ▪ Your current battery is old or shows low voltage alarm.
  • ▪ You are building a new MR-J4 system with absolute positioning.
• ▪ Do NOT buy if
  • ▪ You use linear servo motors (they don’t need backup battery).
  • ▪ Your MR-J4 amplifier already has working battery.
• ▪ Pro tip from our tech team
  • ▪ Keep one spare battery in your spare parts cabinet. Machine downtime costs more than a battery. Replace every 4-5 years even without alarm.
