Roland JV-2080 battery replacement

Post by Marco Koeller » Sat Oct 22, 2016 2:11 am


Hello Roland JV-2080 Users!

On powering up my Roland JV-2080 i noticed the message "Low Battery". After searching the web for instructions how to replace the battery, i didnt found much instructions or discussions about. According to the wonderful explained instructions at, i managed to replace the battery on my own.

So, i decided to take photos of my replacement to demonstrate that is is not that complex to manage.

Okay, first some informations which should be considered:
- Please notice: You replace the battery on your own risk!
- Backup your customer settings and your user presets, the may be gone after battery replacement!
- Make sure you have disconnected the device from voltage before starting the replacement!
- The internal battery of the JV-2080 is a standard "CR 2032 lithium battery", running on 3V.

What tools do you need for the replacement?
- A Phillips Screwdriver (to open the chassis)
- A Tweezer
- Adhesive tape
- Post-It notes
- A cotton bud

Now i guide you through the battery replacement procedure step by step, supported by photos.

1. Remove the screws on the left side and the right side of the chassis. The screws which need to be removed are marked here with red cycles.

2. Remove the screws on the backside of the chassis, as marked red in this photo.

3. Locate the battery on the left side of the mid-leveled board inside.

4. If you want to be sure that nothing shortens the board or other built-in components, place some Post-It notes around the battery holder to avoid the risk of damage. Use the cotton bud to press back the lock on the backside of the battery gentle.

5. Take your Tweezer and fix some adhesive tape with the adhesive side outside, like shown in the photo below. This helps out a lot as you dont have to touch the battery unnecessary. Use this "adhesive Tweezer" to remove the old battery from the board.

6. Pick up the new battery the same way with your "adhesive Tweezer". Make sure that any kind of protective film is removed from the new battery before replacing.

7. Place the new battery where you removed the old one. First, try to move the battery under the lock on the backside of the battery holder. When managed this, press down the frontside of the battery. Make sure the battery really is locked 100%. Keep in mind to act gentle!

8. After remounting the chassis again, connect your device and power up. The "battery low" message should have gone. Go to your system settings, battery status now should be "OK".

9. Restore your custom settings and user presets. If you have used a SysEx-Tool for backup, use this again to restore your data. Alternative, you can playback your user presets from the external storage cards, like M256-E or M512-E.

Additional Info:
In some cases or on some units it can happen, that the display seems not to work after a battery replacement. No panic, the display is not damaged, just the contrast level has been set to zero, as the contrast level has been part of the custom settings. Just press the "System" button on the frontpanel which highlights the display automatically. After that, rotate the value dial to set the display contrast to a value which you prefer.

I hope this little illustrated workshop helps you out when your JV-2080 says: Battery Low :)
