Hook up a battery tender on my 2021 ES350?

[Natty Bumppo]

I will be leaving the car parked in my garage for several weeks and want to keep the battery from dying. On these high tech electric cars that need battery power 24/7 can I just simply connect the battery tender to + then  - posts, and plug tender into a wall outlet? Or is this not recommended for these high tech cars?

My battery tender has 1.3 amp supply.

Thanks all
