4. If you re-charge your discharged 12v battery using a 48watt
(power: watts = volts x amps) solar panel, you should get 4
amps out of it (48/12), and if it keeps up its 4a (which it
won't) you'll get 4 x (the number of hours) of AH back into the
battery.

A 100 amp hour battery. 100/5amps = 20 hours. Yes. 100/50 = 2
hours.
NO! Maybe 20 minutes.

Meltdown!

Well, he was talking in the context of solar panel re-charging.
