How to Replace the Eufy SpaceView Monitor Battery

As a long-time user of the Eufy SpaceView Pro baby monitor, I noticed my battery started dying within a few hours after two years of use. This guide will show you how to replace the battery in your Eufy SpaceView baby monitor.

Firmware Update Tip

Before proceeding with battery replacement, consider updating your monitor's firmware. This can sometimes resolve battery issues. For detailed instructions on firmware updates, refer to my guide on upgrading Eufy SpaceView Pro firmware.

Preparation

Essential Tools

• Replacement Battery: Compatible with Eufy SpaceView Pro T8321-M. I purchased mine from eBay and selected the 3-pin 1.25.
• Small Phillips head screwdriver
• Plastic Opening Tool: I used the iFixIt prying tool to avoid damaging the screen, though some users have successfully used a guitar pick.

Quick Fix Before Replacement

Some users have resolved battery issues by simply detaching and reattaching the battery. Here's a quick reset method:

1. Open the monitor.
2. Unplug the battery.
3. Wait 30 seconds.
4. Reconnect the battery.

If this doesn't fix the issue, proceed with the replacement.

Step-by-Step Replacement Process

1. Opening the Monitor

• Ensure the monitor is off and unplugged.
• Use a plastic opening tool, such as this one, to carefully pry open the monitor along its seams.
• Be cautious around the ribbon cable connecting the screen.

Tip: To remove the front panel, press a small flathead screwdriver flush with the microphone button, push the tip down into the button, and slide it under the case toward the edge. Once it's under a bit, you'll have leverage to pop it loose. Continue around the edge to fully remove the panel.

2. Disconnecting the Battery

• Locate the battery connector on the right side of the board
• Gently unplug it

3. Removing the Circuit Board

• Unscrew the four screws securing the main board
• Carefully disconnect the microphone, speaker, and Wi-Fi connectors
• Set the board aside

4. Accessing the Battery

• Remove the remaining screws holding the battery housing
• Carefully pry out the old battery (it may be adhered to the housing)

5. Installing the New Battery

• Place the new battery from https://ebay.us/dVBMHM in the housing
• Ensure proper orientation, paying attention to the wire cutout

6. Reassembling the Monitor

• Screw the battery housing back in place
• Reconnect all components (Wi-Fi, microphone, speaker)
• Reattach the main board with its screws
• Reconnect the battery to the main board (black cables facing up)
• Carefully snap the screen back into place

Post-Replacement Tips

• Fully charge the monitor before first use
• Properly dispose of the old battery at a recycling center
• If unsure about any step, consult a professional or contact Eufy support

Conclusion

Regular maintenance, including battery replacement when necessary, ensures the longevity of your Eufy SpaceView monitor. I got the information from reddit and youtube.
