Another option is the CTEK chargers. I've got this CTEK one and it works just fine.

I went with the 7A version (looks like a newer version), and connected it in early November when I put the car away for the winter. Very easy to use, and is configurable to our battery type and trickle charge / maintenance mode. See CarGuy11 video for connection location and charger settings. Couldn’t wait any longer so got back on the road yesterday, and car started immediately.

4A verison works fine for me.

If you don't have the battery charger showing fully charged, how do you know the charge state of the battery?

the listed charged that I linked has a display that tells you the bar level of it charged and reduces the amps when it gets close to fully being charged.

I can say the A90 does get discharged for sitting inside a garage and not driven for a few weeks.

Sorry, I meant on the car but I found it on Bimmer Link, it shows percentage. A little frustrating as I drove about 4 hours yesterday and today the battery shows 80%. Nothing has been used on the car but something must be draining it, since after 4 hours of driving yesterday, I would think that the battery would be near 100% of charge.

Winter storage

I have 2020 supra in storage for winter. I have tried two different trickle chargers. They show green to start then give yellow error light after running for awhile. I know the car turns off “nonessential devices” after a period of time (5 min with car locked and key not near car) and wondered it this has anything to do with it?
So: 1. Are the electronics affecting my ability to do maintenance charge. 2. If so, can I just go directly to the battery? 3. Do I need to do any of this? Can battery last 8 weeks without charging? Would there be any issue with just unhooking the battery to avoid slow discharge?

I like simple so I just hooked up a Battery Tender Jr in Sept last year and will be pulling her out of hibernation come April. I plug the battery tender to the charge posts under the hood. I do this on my other 2 cars in hibernation as well. No issue. You can keep the doors locked or unlocked. Doesn't matter.
