The battery tenders I have made by Schumacher are max 1 1/2 amp output and says it monitors voltage and turns off when max charge is reached and will turn on again when voltage drops more than 1 volt.

Very small flat box with short cord. I have them permanently mounted out of the way near battery and just run an extension cord when car is parked.
