Must be the turbocharged version.I have never seen a women's toy that uses huge and heavy D-cells. It must be very powerful..
radio Shack and Digi-Key both used to sell the "full power" NI-CAD cells in both C and D size (not the fakes with a little cell inside). Surprising how heavy they are.Energizer sells C and D Ni-MH rechargeable cells that have a little AA cell inside.
If I understand right, since my solar panel puts out around 433 mA/hour, it would take about 2.5 hours to charge one AAA battery at 1000 mAs.
400 mA x 2.5 = 1000
The 9000 mA battery should take about 22.5 hours to charge.
400 mA x 22.5 = 9000
Only problem is that you're assuming that the charging process is 100% efficient. Add 20-30% (probably don't need to add that much honestly) and you'll be fine. And don't worry about overcharging those D cells with only a 400mA charger, it won't hurt em.
While charging your battery with the solar panel, how will you stop the sun (the earth) at the noon position?
The current might be 400mA at noon in summer but will be much less at other times.
I have many solar garden lights. They work fine in the middle of summer and glow all night long.
But now in the fall the sunshine is weak and not for long. They glow for about 2 hours following a sunny day and for only half an hour or less following a cloudy day.
I don't see them glow in the winter.
They are cheap (many were free) so their light output is almost nothing.
There are no poor people in my city. All the American criminals are in jail. So there is no stealing. Even school kids do not steal solar garden lights.How do you keep people from stealing them?
Well years ago in chat all da gals said they had major trouble keeping their BOB's fully charged. I simply suggested to them to use re-chargables and stop buying new batteries everyday. The things thrown back at me were from marriage proposals to you dirty ol' bugger. By the way a BOB is known as a Battery Operated Boyfriend......
