Maplin Solar Battery Charger - Anyone got one?

I just bought one => http://www.maplin.co.uk/Module.aspx?...rger&doy=18m11

Now, the manual says that the LED will flash when charging is taking place. However, the LED on mine flashes when it's not connected to anything, but as soon as I connect it to a battery the LED goes out. Does anyone know what the story is here? Or have one that the same thing happens to?

I suspect the LED flashes to indicate when there is an excess of voltage present - in other words maybe it will only flash when the battery is fully charged? Often these manuals are totally wrong - transalation from Chingrish doesn't help!!!

I have come to the conclusion that;

Power generated by the solar charger today (dull day) < Power already in the battery

Hence no charge, hence no flashing LED!

Alt, Ive just seen your link. Do these work reasonably well??? I have a dual battery setup so when I leave the boat, I switch it to run off 1 battery only, but that battery can drain if I leave it for a while, particularly with the auto bilge pump working overtime in this weather.

Are there any other similar products available which people can recommend for a budget of < 50.00??

regards

Don't have it long enough to comment, but a guy at my boat club has one on his RIB and his battery never went dead, even with an auto bilge pump. Caused a bit of the oul electrolisis (sp?) though

as i said mine is left on all year. boat just been lifted out but has worked all season with auto bilge pump working and been left for long periods with lots of rain, battery always has plenty of power for starting and the opti takes a bit of power to turn. i give it a 10 out of 10 and it was very cheap from maplin. i just remove it before using the boat.

Solar panel and charging

My apologies for the unintended last thread, pushed the button at the wrong time!!!
Regarding this solar panel, I have used one on a fuel bowser to constantly top up a golf cart battery which in turn operates my small 12V electric fuel pump. The fuel bowser dispenses fuel for my boat and other ground equipment. It has been totally successful and after a period of approx 4 years bolted to the top of my bowser is still suppyling excellent service.
I also have a much larger solar panel fitted to my boat at approx 35W output which for a good number of years has been topping up my dual batteries through a regulator, supplying an anchor light and small interior light. I am a great believer in solar power for the correct applications. Don't expect miracles however good efficient service in the correct mode. I hope this is useful.

just ordered one at 9.99, can't go to wrong at that price, will place on top of A-frame, out the way.

Do you think it would be ok to keep it continously connected to battery??
