I just purchased a secondhandMaha Powerex MH-C800S ... on eBaywhen the charger arrived. I plugged in for batteries, and the LED screen came on, and I believe the charging mode had started. When I checked on the charges the next day. I noticed two of the batteries had leaked. I cleaned up the charger, but now it does not seem to work. The LED light does not come on. The power supply light is on. Could I have blown this charger out with a bad set of batteries? If so does anyone have any suggestions as to what I can do. Like I said I did not purchase this new.
