This charger is an overnight type of charger, something the description hinted at, but I didn't read it well enough(no fault of the charger, so no loss of stars by me). It does charge the batteries I use well, though, with the one fault being that it doesn't shut itself off after it finishes charging, which can harm your batteries if not monitored properly. There are better on Amazon for the same amount of cash, though, so do a better job than me and search for them on here.
