I got that also with my charger. However, the indicator LED's don't follow the published sequence. I contacted Zero engineering and they said they were aware of that and were working with Delta-Q to straighten it out. They said to go ahead and use the charger even though it continues to do a full current charge for awhile after the green LED indicates that it is at full charge. The charge current level bar-graph LED's don't ramp down, it just stays at the top one and then goes dark while the current is still at high level as indicated by my Wh meter. After about five minutes, with the green indicating full charge that whole time,, it starts ramping down as indicated only by my Wh meter on the AC input, since no current bar-graph LED's are lit. At no time during the charge does the 80% LED come on.
I explained all of this to Zero and they said it was OK, they are aware (as I said earlier). They think that Delta-Q has set the full charge indicator to come on at 90% so it stays on high charge current for awhile.
The chargers on my earlier bikes followed the published LED indicator sequence.
Has anyone else observed this change in the chargers LED patterns?
BTW- The paperwork that came with the charger said it was algorithm #99, 48v output, lead acid. The label on the charger said 96v output, lead acid battery. Zero said that was OK and to use it and it worked, but with the odd LED sequence I reported. I notice that your paperwork says algorithm 123, Emoli, Li ion. Very strange stuff!
I measured my battery no load voltage, after the charge ended, and it read 113v so it doesn't seem to have overcharged my battery but the label and the incorrect paper are worrisome.
