I just purchased a brand new Maha C9000 charger and received it today. It worked for about an hour letting me charge 4 AA newer batteries. I then tried to use the Refresh/Analyze option on 2 of my older AA batteries. About 10 seconds into the process, everything went kablooey on the LCD...random characters all over the LCD for about 10 seconds, and then everything disappeared off the LCD. I can still hear the low frequency whistling noise, but it's solid, not pulsating. I unplugged it from the power and waited 5 minutes. Turned it back on without any batteries, and it just showed a bunch of random characters all over the LCD and then...nothing. Inserting a battery still shows nothing on the LCD...but the LCD still gets backlit for a few seconds.
Has this happened to anyone else? Will the manufacturer replace it? I already emailed them and waiting for a response.
