None of these have within an order of magnitude of the needed current to charge these batteries. Hmm, letssee... typical deep discharge 12 volt battery is 100 amp-hours. At 1.8 amps charging, one would need about 55 hours of sunlight a day (assuming 100% effeciency) to recharge the thing. Funny, I misplaced my collection of 72 hour days. All I have now are 24 hour one. Won't work. -- John De Armond, WD4OQC | Manual? ... What manual ?!? Sales Technologies, Inc.
