Charging time 16 hours

I for over a year now use the device for charging my eneloop batteries. The unit recharges the batteries reliably. The charging time is approximately 16 hours. The end of charging is indicated by the green lights go out. This will only work if you do not interrupt the charging process. Other brands of batteries should not be loaded with the device in principle, because otherwise they possibly leak. But Energizer batteries also work. There is also a slightly more expensive fast charger, which I have not tried.
