I've just found a solar battery
maintainer on a 'green' website. This is the description
'DZ Energy's 170mA solar battery
charger is a 2.6W solar powered car battery
maintainer that will trickle charge a 12V car battery
, keeping it topped up. It's weatherproof, and ideal for cars, small boats, tractors and other vehicles'
Any idea if its a good gadget? - just thinking about those campsites & festivals that don't have hook up
I know the chances of enough sunshine
could make it useless but .......
