Deltran Battery Tenders
Black and decker makes one that just works. I have had mine since 2015 and it's the best and most reliable battery tender / charger I've ever had. They still make them and I bought an additional one last summer and it's as consistent and reliable as the first one I bought in 2015.
Kept the lawn mower battery ready to go, all winter long and does it all
