4 AA's, thus a nominal voltage of 6v. Putting a solar panel might blow re-chargeables without some sort of controller/voltage limiter. But I have limited knowledge about these things.

I do have solar panels on the boat, and they go through a controller....


Edit...I see on Ebay you can buy a 6v solar panel...……………..:-)

Solar cells have a high impedance whereas re-chargeable cells have low. In that case the solar cell voltage will be 'pulled' down to that of the cells'. I'm uncertain what would happen when the cells become fully charged, though.

Re: Best AA Batteries

Could you not run a 6v mains power supply to it? just plug it in to the mains then.

Nor me...……

I do live in Wales though, we did see the sun recently...………:-)

Yes full on sun will certainly charge up the batteries, I reckon from zero they take about 4 hours from the wall charger. But not sure if the batteries just don't take anymore umph, or the charger slows down to a trickle....not an electrician nor electronic engineer. Just an old git now,,,....

Make sure the mains bit is indoors though and just run the 6v feed outside!

Jax, you really do need to modulate the width of your pulses.

Mark, I will come back to you about charging the cells. Just on my way out now.

I didn't say that because I thought it was just too obvious .... but happy you said it anyway.

Re: Best AA Batteries

It should be obvious of course but having worked with electronics and customers for years one can never be too sure what is and isn't obvious! Over the years several people have complained that their enlarger timer must be faulty because the enlarger lamp is not coming on when in fact the reason is the bulb has blown .

Always assuming the washing line pole isn't 200 feet from the nearest indoor mains socket.
