The 808 is a quirky charger. I'd just stop the discharge and recharge the cells and try another conditioning cycle after the cells have a couple of cycles on them. Also, a UPS with a filtered power supply may reduce some of the 808's eratic behavior in some locations. For a charger often touted as 'Professional' it seems somewhat intolerant of dirty AC and it goes into amnesia if it loses power for even a half second. Either of these faults would seem to pretty much rule it out for professional use in most Third World countries -- and at least a few First World cities like New Orleans.I recently purchased about a dozen of the powerex 11,000 mah D cell and proceed to condition 8 of them in the 808. after 5 days. the 808 seems to get stuck at the discharge cycle with 1 bar blinking on all slots without going into the final charging cycle. The 808 seems to be overwhelm by the capacity of the D cell :thinking: and their algorithm get mixed-up because of the time needed to discharge those D-cells????
