Hmmm. I would have thought "connected in parallel" not series.
If it can do 86 amps for 5 seconds then it can do 20mA for about six hours...but that's to discharge to half voltage so your LED would be dim. If you run at 10mA you might be OK but it would take two connected in series to keep your LED at 20mA all night.
In practice, to drive any LED other than a red one, you would need to use a boost converter.

Yes, but then you would have the problem of making sure that they charge equally.

I found this 1 legged transistor with arms.
