I use this:
https://no.co/genius2d
https://www.amazon.com/NOCO-GENIUS2D-Direct-Mount-Temperature-Compensation/dp/B07W3QSMF9?ref_=ast_sto_dp&th=1
And everything works perfectly. No more deep sleep warnings.
I use it once a week for a few hours to keep the battery topped off.
I scratched the side mirror when removing adhesive which held blind spot mirror.
The side view mirror glass is not the same as a windshield or window.
It is very sensitive and does scratch.
My Driver side mirror has scratches on it and I would like to replace the glass only. It has BLIS and is heated.
I saw this on eBay and was wondering if anyone has any feedback...
Would it be possible to get a picture of how you connected it. I am thinking of doing the same. I could not get the 10mm bolts off to connect the Noco Genius 2D. Thank you for your help.
