I have optima batteries in a lot if the cars- they have a pretty good warranty and can usually be brought back from the dead with a deep charge.
I’ve had Schumacher chargers before with success, but this one just gave it up early, I bought it on Amazon and we’ve had a few things from Amazon that obviously were knock offs. I doubt it but maybe.
Thing is there are not many other options. I used to buy. Craftsman chargers but they aren’t too readily available and no idea who is actually making it.
