Hi there. I ordered an ESQ-1 battery from here and just took a few hours to swap the battery. I turned the synth back on afterwards and I’m still getting the low battery message. I factory reset it, same thing.
I made sure to put the battery in the correct orientation. Does anyone know why this may be happening?
I’m assuming that you checked the new battery with a voltmeter to make sure it was at full potential? Sometimes batteries that hang around for years lose charge…
Sorry, got busy with work. I hadn’t checked before since I wrongly assumed it would work. I will check now
Okay now I’m really confused. The battery is measuring above 3.3 Volts DC
Do you have everything put back together? If the keybed is left disconnected for example the Low Battery warning may still not go away.
I know this is old, but I kept the synth on for months to keep the patch memory. The synth worked fine during that time. I decided to open it up and add more solder per someone’s suggestion. Now the synth constantly says low battery. I don’t know if the battery was shipped to me originally with low voltage but it looks like I’m going to have to try again with a new battery.
If the btter is still good then It could be a bad solder joint or a broken trace
There are other problems that can cause the low battery message. Check out page 9 of the service manual, it has some info about tracing down the problem. If the battery measured around 3 V then the battery is good and your synth may have a problem elsewhere.
