Hi Linda,
The only thing I would add to your excellent summary is that it's best to wait about a half hour after riding bike, before charging, in order to let the battery cool down. This is more important after a long or hard ride. If you don't let the battery cool down, you can get a "false green" response where the charger thinks the battery is fully charged because of its temperature, and you'll get the green light (and the charger stops charging). In this case, the false green will happen within the first 15 minutes of charging, and if you just turn the charger off and turn it back on again the light will go to amber and the battery will charge like normal.
This is true for Li-ion and NiMH batteries, but not lead acid.
best,
Sarah

Subject: [ebikes] Lithium battery chargingI have been asked a question about how I am charging the battery on my
Ezee Quando II. I looked up the proper way to charge the lithium ion
battery on the web because I thought it would be very different from
the metal halide or other batteries. I was right, the references say
that we should recharge the batteries frequently and not let them get
too discharged. The charger that comes with the bike is set up to
charge at the correct rate, so using it is very important. If you're
going to store the battery for long periods, just leave it partially
discharged and put it in a cool place, even the refrigerator.
Does anyone have more information?
