Property unfortunately the manual is no longer, but it can not be acceptable but that a charger starts to burn when you put into it 4 batteries of the brand Eneloop. I had not seen it on the side of a switch 2/4 has previously stood always on 2 and put this on 4 order 4 batteries to charge what did not work before. A few seconds on AC power acknowledged the device with a lot of smoke, and then fire from the inside out, the part could still throw in the bath. 2 The batteries could I remove it from the device were piping hot and the other two cold !!!
