Red Battery Warning Light After Trickle Charging

[sethsquire]

I have a third car for a few months so the Blackwing is mostly chilling in the garage, and I purchased a Noco trickle charger to make sure the battery doesn't go dead. I placed it on the terminals under the hood, it blinked red for while indicating that it was charging before eventually going green, and has stayed like that for the last couple of weeks.

I felt like taking a drive today and pulled off the charger and fired up the car. Immediately the red battery warning light illuminated on the dash. I drove a short distance, turned the car off and turned it on again and the battery light disappeared. It did not reappear and the car seemed to be functioning within normal parameters.

Has anyone else experienced this?

My 5 has been on a Noco maintainer using under hood terminals for 2.5 years with occasional weekend use and never have seen a battery light.

Usually always keep the trickle on mine when not using. Same battery since Dec. '21.
