Hello. Is it ok to trickle charge the battery while it is still hooked up to the car with both positive and negative terminals?

i use a battery tender 1.25 amp i never unplug the trunk battery i use the alligator clip on the underhood conections.posi red and negative on the grounding post..have used it on my last 3 challengers.
There are a few purists who say a tender should be attached to the battery directly; underhood connection means the SOC (State Of Charge) shunt on the negative battery terminal sits between the maintainer and the battery.
I'll note a difference here between a battery maintainer and a charger. A maintainer is designed or at least intended to maintain the battery in storage, a charger is intended to add power to a discharged battery.
I have a small charger (had it for decades), typically will do 4 amps on a mildly on-the-edge battery which needs a boost to start a vehicle; it may need hours to a day to do its job, gentle on the battery but do not leave it hooked up longer than needed. I also have a battery maintainer for winter storage (link below). I hook it up under the hood. Either consider me not a purist or someone who does not want to create an air leak in the trunk weatherstripping with the wiring.
A maintainer can charge an on-the-edge battery in theory but it might take a day or three. It is not a charger.
Final note: There were some chinesium forgeries on Amazon during CoViD. I bought from O'reilly as it seemed to be authentic product. Some buyers on Amazon reported getting very light product, it should feel like there is some dense parts in it.

I have a maintainer on my car constantly if it’s not being used. My car only goes out once or twice a year for a couple of hours, the original battery lasted 12 1/2 years. I’d never think that was possible. My other collector car and my 3 motorcycles also are plugged in to their own units.
If you need to lock the doors while in your garage, you need to move.
The LAST thing you want to do is try to get to a dead battery when the car is in the garage.
If anything, just leave the trunk open and lock the doors. But don't dare close the trunk until your dash goes alive in your presence.
