Cannot Clear "E Bike battery low" warning

I approached Garmin Support, this is the highlight...

"So, Garmin devices reflect the behaviour on behalf of third party units. IF a third party device is constantly prompting a low battery, then the Garmin device will reflect that and let it's user know. Behaviour like this being exhibited is more likely to come from a third party source than from the edge unit directly."

"I can get this raised further - so long as we have a video of the behaviour - but I'm not 100% confident it's something that we'll be able to fix, as there's a decent chance the problem is stemming from another source."

As many other types of alerts can be disabled I then asked if a change request could be raised so that this alert type can be disabled.

To make progress down either route we'll need video of the issue.

So I have a 1030 plus and same thing happened to me this morning. Sooooo annoying being constantly told your battery is "critical" even though you have a range extender. Would this alert still pop up if you removed the battery % data field and just left the "travel range"?

I finally manged to capture the issue on video so have submitted it to Garmin support. Interestingly the low battery warning continues to appear and re-appear even when the e-bike is no longer connected to the head unit. In my case the e-bike was switched off and is now about 100m away from the head unit but I still get the same looping issue. The suggests to me that the issue is with the head unit.

I have the Edge 1040 with the latest SW and a bike with Mahle X20 and range extender and the same issue appeared in my recent ride. When the range extender was down to approximately 10%. Switching off the electric system did not clear the warning message and left the Edge device nearly useless.

I've not heard back from Garmin tech support, so have chased them up. 

For reference they asked me to provide them a ride file with extra information in it. If your battery is still in the low state or you know it is likely to happen on a ride it might be worth recording it as per below and raising a bug with Garmin.

Did you manage to send in this further information?  I too get this error message and I get it every time I switch on my battery even when it’s 100%.  Really frustrating having to keep hitting the screen of the garmin 830 to remove the message. I’ve tried everything to remove it and would love to get a fix.

Not sure who you were asking the question of, anyhow from what you've written there are two things going on.

1. Low battery warning when switching on the bike, something that appears to be a common issue - just a one click nuisance really.

2. Being locked in a repeating loop when the range extender battery falls to a low level - which renders the head-unit useless.

Please raise your issues as bugs with Garmin & they may prioritise fixing them.
