How to Replace and Use the Toshiba ER3V 3.6V PLC Battery with Clip

Step 1: Prepare & Power Down
Turn off the PLC or controller and isolate power to the panel. Confirm the system is powered down to prevent data loss or electrical hazards during battery replacement.

Step 2: Locate the Battery Socket
Open the controller enclosure and identify the memory backup battery socket. Refer to the equipment manual for the exact battery location and orientation. Note any polarity markings.

Step 3: Remove the Old Battery
Carefully release the existing battery clip or connector. Use an antistatic wrist strap if available and avoid metal tools that could short terminals. Take note of clip orientation for correct re-installation.

Step 4: Install the New ER3V with Clip
Attach the Toshiba ER3V to the supplied clip, ensuring the cell’s positive and negative ends match the socket markings. Snap the clip into the socket firmly but gently; do not force. Confirm the battery is seated securely.

Step 5: Power On & Verify
Restore power and check the PLC’s memory/clock settings. Some controllers require a brief initialization after battery replacement—verify normal operation and saved parameters. If the controller shows a memory error, recheck the clip orientation and contacts.

Step 6: Record & Schedule Maintenance
Log the replacement date and battery model in your maintenance records. Plan the next check or replacement per equipment guidelines (commonly 3–5 years depending on usage and ambient temperature).

Troubleshooting

• No memory retention after replacement: Re-power and confirm correct polarity; inspect clip and socket for corrosion or bent contacts.

• Intermittent faults or resets: Ensure clip is fully seated and that the battery is genuine Toshiba ER3V (counterfeit/incorrect cells can fail).

• Visible leakage or damage: Safely remove the battery, clean the socket with isopropyl alcohol, and replace damaged parts; follow EHS disposal rules for lithium cells.

Following this process keeps PLC backup systems reliable and minimizes production downtime across UAE facilities.

Q1: Is Toshiba ER3V 3.6V Lithium Battery rechargeable?
No. The Toshiba ER3V is a primary (non-rechargeable) lithium cell. It is specifically designed for long-term memory backup in PLCs and similar devices and must not be recharged. Attempting to recharge a primary lithium cell can be dangerous and may cause leakage or rupture. For applications requiring rechargeable power, choose a dedicated rechargeable battery chemistry and follow the device manufacturer’s guidance.

Q2: What is the capacity of the Toshiba ER3V battery?
The ER3V is rated at 1200mAh, which provides reliable backup duration for PLC memory modules and control boards. Capacity and effective backup time depend on the host device’s standby draw; devices with very low memory drain can retain memory for multiple years. Always verify backup time estimates with the PLC manufacturer and replace the battery as part of scheduled maintenance to avoid unexpected memory loss.

Q3: Where can I buy the Toshiba ER3V 3.6V PLC Battery in UAE?
You can purchase the genuine Toshiba ER3V battery with clip from the Sea Wonders product page and other industrial suppliers listed online. Ensure you buy authentic cells that include the correct clip/plug and match the ER3V model number (ER3V / JZSP-BA01) to guarantee compatibility and safety for your PLC system.

Q4: Is the Toshiba ER3V compatible with Yaskawa and other PLC brands?
Many automation modules that accept ER3V-spec cells will work with the Toshiba ER3V, but compatibility depends on the device socket and voltage/current requirements. Check your PLC or controller manual for the recommended battery part number. If the equipment manual lists ER3V or JZSP-BA01, the Toshiba ER3V with clip is an appropriate replacement.

Q5: How long will the ER3V maintain PLC memory?
Shelf life and in-circuit backup time vary by device current draw and storage conditions. Under typical low-drain backup conditions, Toshiba ER3V cells can maintain memory for several years. For mission-critical systems, implement a replacement schedule (often every 3–5 years) and monitor battery status during routine maintenance to prevent unexpected data loss.
