Hi All,
I've been having a bit of a problem charging my 12V 7Ah SLA battery using my Maplins 13W fold up solar panel connected to a small LED light in the bathroom. The first battery was ok for a few months, but then the light suddenly died and thought that the battery wasn't charging because of the faulty controller that came with the panel. So I changed the controller and put in a new battery.
This again worked for a short while before it stopped working again. When I measured the voltage across the battery it was around 18V!!! I have no idea why this is.
I made the LED light myself, 3xCREE XPG emitters in parallel on an aluminium heatsink.
Can anyone offer some advice on this?
Thanks
