I don’t leave a fob in the vehicle. Expect the batteries to run dead flat over night. Even with NOCO battery “maintainers” they let the batteries drop below 12.3 volts. Over time batteries will need replacing prematurely. Im still looking for a suitable maintainer in excess of 10 amps. Any advice welcome

Yes. Regular key. Screen turned off. Dimmer turned all the way down. Constant drain about 5 amps. I can maintain battery @ 12.6 volts. Chevy Duramax. High Country.

Sorry. Computers are too clever for me. what is your WiFi extender? Thanks

I would like to know what the battery drain is. 2017 Silverado when accessory is on? Got caught with battery charger/ maintainer quitting when battery is fully charged and does not restart. It’s what they do. I bought a 5amp maintainer. Wasn’t enough. So tried a 7.5 amp one with all the bells and whistles. Battery went from 100% to <75% in a few hours. Back on the charger. Just need to remember to unplug it periodically. I think more than 5 amps is excessive. I noticed after snowfall the other night 2” the area around the rear view mirror was clear of snow indicating a lot of heat. Ideas anyone.
