Taranis RTC resets - battery OK

[CJB]

I can not keep the RTC to operate once I turn it off. Something, someone may know a simple fix (I'm hoping).
My radio is a Taranis X9D SE with 2.3.11 firmware.
It's over 2 years old and everything else works flawlessly. However, I'm tired of resetting clock and date at every start up, especially when I need time stamps for logs.

I do not get RTC low warning because:

Battery was replaced and the RTC voltage in HARDWARE reads - 3.5 volts. I've poured over the internet and solutions are all over the place. I honestly don't believe all answers work because they're too weird. The only suggestion not given was: Put on your ruby shoes and click your heels together while saying 'There's no place like home".

I hope this doesn't mean sending in the Tx.

We are always happy to take a look. but it is almost always that battery. Can't think of anything else. Make sure it is installed correctly.

Hi Wayne,

I am certain it is NOT the battery, I bought a batch of them (Lithium 3.3V CR1220) off Amazon and gave one to my flying buddy (his died) and it works fine. I just put one in my son's old Taranis and it works!

What do you need for me to do to send it?

Just email us at contact@alofthobbies.com and let the team know about the issue, or just link to this thread. They will get you the details for sending the radio in for service.

Sorry for the trouble!

John - Did you ever get your RTC to work? I'm experiencing the same issue.

When you replace the RTC battery, you have to set the time twice to have the radio remember it. Set the time, turn off the radio, turn it back on and set the time again, then turn it off and on again and it should show the correct date and time.

Hey @darkside_floyd1, usually if it's not the battery, it points to an issue with the RTC circuit on the mainboard. Did you ever send it in for service? It's often the most reliable fix for persistent RTC problems after a battery swap.
