I am not using these anymore since I got the 40D for fast AF applications so they have to go. I have owned them for 2 years and recharged them maybe 10 times only. The Delkin RCR-V3 pair was recently purchased and used once only. The chargers are auto-detected 110/220V and take about 3 hours to charge an empty set. These RCR-V3 are safe with "loaded" voltage less than 3.1V (I measured them individually myself) despite the "open" voltage is about 3.6V. I am asking CAD/USD$50 for the lot + $10 shipping in Canada or to the US. Will take Paypal.
