1.8 Watt Solar Battery Trickle Charger: [ Ссылка ]

Do you have a car, lawnmower, 4-wheeler, dump trailer, or any other application where you have a battery that sits for long periods and always goes dead just when you need it? A Simple $20-$30 solar trickle charger might be a way to avoid these inevitable headaches. I will test out a 7-watt panel to see if this will actually work without the need for a charge controller between the panel and the battery.
