Newbie with battery charger question

[net wurker]

Just got my first E-bike. Shimano STEPS E8000 system. B8035 battery, and BC 6002. I can't find a clear answer by looking at Shimano's web site, or Googling.

Once the battery is fully charged, the LED light goes out on the charger. Does this mean the charger has actually shut off and not still putting a charge into the battery?

I usually ride at night and when I get home, I put the charger on the bike. If it goes out around, say, 2:00 am. does the charger actually stop charging at that point? I don't want to fry my expensive battery by over charging it, but it would suck to have to get up in the middle of the night to remove the charger.

Thoughts on this? Thanks in advance.

You are correct with all your thoughts. Once the battery is charged, it stops pulling power and shuts itself down.

Thanks! Now I can sleep easy at night.

Remember that you do not charge the battery immediately after riding, but let it cool down first

Thanks, good thought. Mostly I drive to the trailhead, about half an hour, so I guess that is sufficient cool-down time? I'll have to keep this in mind after neighborhood blasts, though.

Yeh I think I nuked a battery after whacking it on charge after a very demanding climb

You'd think the controller would inhibit the charging under those circumstances, it knows the battery temperature. I know my tool batteries will refuse to charge when they're still too hot from just being used hard, even the cheap copy ones. The charger throws up an error state and you have to let them cool off.
